+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+
+This directory ("Binary") is part of the RomWBW System Software 
+distribution archive.  It contains the completed binary outputs of 
+the build process.  As described below, these files are used to 
+assemble a working RetroBrew Computers system.
+
+The files in this directory are created by the build process that is 
+documented in the ReadMe.txt file in the Source directory.  When 
+released the directory is populated with the default output files.  
+However, the output of custom builds will be placed in this directory 
+as well.
+
+If you only see a few files in this directory, then you downloaded 
+just the source from GitHub.  To retrieve the full release download 
+package, go to https://github.com/wwarthen/RomWBW.  On this page, 
+look for the text "XX releases" where XX is a number. Click on this 
+text to go to the releases page.  On this page, you will see the 
+latest releases listed.  For each release, you will see a package 
+file called something like "RomWBW-2.9.0-Package.zip".  Click on the 
+package file for the release you want to download.
+
+ROM Firmware Images (<plt>_<cfg>.rom)
+-------------------------------------
+
+The files with a ".rom" extension are binary images ready to program 
+into an appropriate PROM.  These files are named with the format 
+<plt>_<cfg>.rom. <plt> refers to the primary platform such as Zeta, 
+N8, Mark IV, etc.  <cfg> refers to the specific configuration.  In 
+general, there will be a standard configuration ("std") for each 
+platform.  So, for example, the file called MK4_std.rom is a ROM 
+image for the Mark IV with the standard configuration. If a custom 
+configuration called "custom" is created and built, a new file called 
+MK4_custom.rom will be added to this directory.
+
+Documentation of the pre-built ROM Images is contained in
+"RomWBW User Guide.pdf" in the Doc directory.
+
+ROM Firmware Update Images (<plt>_<cfg>.upd)
+-------------------------------------
+
+The files with a ".upd" extension are binary images identical to the
+.rom files, but they only have the first 128K bytes.  The first 128K
+is the system image without the ROM disk contents.  These files can be
+used to update the system image without modifying the ROM disk
+contents.  Refer to the RomWBW User Guide for more information.
+
+ROM Executable Images (<plt>_<cfg>.com)
+---------------------------------------
+
+When a ROM image (".rom") is created, an executable version of the 
+ROM is also created.  These files have the same naming convention as 
+the ROM Image files, but have the extension ".com".  These files can 
+be copied to a working system and run like a normal CP/M application.
+
+When run on the target system, they install in RAM just like they had 
+been loaded from  ROM.  This allows a new ROM build to be tested
+without reprogramming the actual ROM.
+
+WARNING: In a few cases the .com file is too big to load.  If you get 
+a message like "Full" or "BAD LOAD" when trying to load one of the 
+.com files, it is too big.  In these cases, you will not be able to 
+test the ROM prior to programming it.
+
+VDU ROM Image (vdu.rom)
+-----------------------
+
+The VDU video board requires a dedicated onboard ROM containing the 
+font data.  The "vdu.rom" file contains the binary data to program 
+onto that chip.
+
+Disk Images (fd_*.img, hd_*.img, psys.img)
+------------------------------------------
+
+RomWBW includes a mechanism for generating floppy disk and hard disk 
+binary images that are ready to copy directly to a floppy, hard disk, 
+CF Card, or SD Card which will then be ready for use in any 
+RomWBW-based system.
+
+Essentially, these files contain prepared floppy and hard disk images 
+with a large set of programs and related files.  By copying the 
+contents of these files to appropriate media as described below, you 
+can quickly create ready-to-use media.  Win32DiskImager or
+RawWriteWin can be used to copy images directly to media.  These
+programs are included in the RomWBW Tools directory.
+
+The fd_*.img files are floppy disk images.  They are sized for 1.44MB 
+floppy media and can be copied to actual floppy disks using 
+RawWriteWin (as long as you have access to a floppy drive on your 
+Windows computer).  The resulting floppy disks will be usable on any 
+RomWBW-based system with floppy drive(s).
+
+Likewise, the hd512_*.img and hd1k_*.img files are hard disk images.  
+Each file is intended to be copied to the start of any type of hard 
+disk media (typically a CF Card or SD Card). The resulting media will 
+be usable on any RomWBW-based system that accepts the corresponding 
+media type.
+
+NOTE: The hd512_*.img files are equivalent to the hd_*.img
+files in previous distributions.  The hd1k_*.img files
+contained a revised file system format that increases the
+maximum number of CP/M directory entries from 512 to 1024.
+Refer to the ReadMe.txt in the Source/Images directory
+for details.
+
+Documentation of the pre-built disk images is contained in the 
+DiskList.txt file in this directory.
+
+The contents of the floppy/hard disk images are created by 
+the BuildImages.cmd script in the Source directory.  Additional 
+information on how to generate custom disk images is found in the 
+Source\Images ReadMe.txt file.
+
+The psys.img file contains a full implementation of the UCSD p-System 
+for the Z80 running under RomWBW.  This image file must be placed on 
+disk media by itself (not appended or concatenated with hd*.img files.  
+Refer to the Source/pSys/ReadMe.txt file for more information on the 
+p-System implementation.
+
+Propeller ROM Images (*.eeprom)
+-------------------------------
+
+The files with and extension of ".eeprom" contain the binary images 
+to be programmed into the Propeller-based boards.  The list below 
+indicates which file targets each of the Propeller board variants:
+
+	ParPortProp	ParPortProp.eeprom
+	PropIO V1	PropIO.eeprom
+	PropIO V2	PropIO2.eeprom
+
+Refer to the board documentation of the boards for more information 
+on how to program the EEPROMs on these boards.
+
+Apps Directory
+--------------
+
+The Apps subdirectory contains the executable application files that
+are specific to RomWBW.  The source for these applications is found
+in the Source\Apps directory of the distribution.

-Building a Custom ROM
----------------------
-
-At present, the build environment assumes you are running
-a current version of Microsoft Windows (either 32-bit or
-64-bit).
-
-If you are using Linux, David Giles has contributed a Linux
-makefile that should work for you.  Please read the
-LinuxBuild.txt file for more information.
-
-All required tools are included in the distribution.  You
-should not need anything other than what comes as part of
-Windows or as part of the distribution.
-
-In summary, the process involves the 4 steps below:
-
-  1) Create/update configuration file
-
-  2) Update/Add/Delete any files you want incorporated in
-     the ROM Disk
-
-  3) Run the build script (or makefile if you prefer) and
-     confirm there are no errors.
-
-  4) Burn the resultant ROM image and try it.
-
-The process is really very simple.  In fact, you can
-essentially skip steps 1 & 2 if you want to try simply
-building one of the existing configurations.
-
-Each of the 4 steps above is described in more detail
-below.
-
-1. Create/Update Configuration File
------------------------------------
-
-The settings for a build are primarily controled by
-a configuration file that is included in the build
-process.  In order to customize your settings, you
-need to modify an existing configuration file or
-create your own.
-
-If you look in the Source directory, you will see
-a series of files named config_xxxx_yyyy.asm.  Each of
-them corresponds to one of the standard configurations
-listed in the ROMList.txt file.
-
-You have two choices.  You can simply modify the existing
-configuration file that is closest to your situation, or
-you can copy it to a new config_xxxx_yyyy.asm file and modify
-that.  I recommend that you copy one to your own name so
-that you will always have the unmodified standard configuration
-files left in place.  So, for example, you could just
-copy config_ZETA_std.asm to config_ZETA_wayne.asm.  You MUST
-name your config file as config_xxxx_yyyy.asm.  The xxxx's
-must match your platform (N8VEM, ZETA, N8, S2I, or S100).
-The yyyy's can be whatever you want.
-
-The config files are simply text files with various
-settings.  Open your target config file with your
-favorite text editor and modify the settings as desired.
-
-Unfortunately, I have not yet documented each of the
-settings in detail; that will be a separate document
-provided in the future.  However, there are comments
-in the config file that will probably be sufficient
-for the most part.
-
-2. Update/Add/Delete ROM Disk Files
------------------------------------
-
-The files that are included on the ROM Disk of your
-ROM are copied from a set of directories during the
-build process.  This allows you to have complete
-flexibility over the files you want included in your
-ROM.
-
-If you look at the RomDsk directory, you will see
-a variety of subdirectories.  These subdirectories
-contain the files that will be included in the
-ROM disk.  The build process will determine
-which subdirectories to include files from based
-on the following rules:
-
-First, all files from either std_512 or std_1024 will
-be incuded depending on on the size of the ROM you
-are building.  If you are building a 512KB ROM, then
-all the files from std_512KB will be included.  If you
-are building a 1MB ROM, then all the files from std_1024KB
-will be included.  Essentialy, the files in std_1204KB are
-a superset of the ones in std_512KB because there is more
-space available for the ROM drive.
-
-Second, all files from the directory that corresponds to
-your configuration file will be included.  If you build
-the "ZETA_std" configuration, all files in cfg_ZETA_std will
-be added.  Note that these files will be in addition
-to the files from the std_XXXKB directory.
-
-If you created your own config file (like config_ZETA_wayne.asm
-described above), you MUST create a subdirectory within
-the RomDsk directory and populate it with the files
-you want added.  Normally, you would include the
-files from the original standard config.  So, if
-you created config_ZETA_wayne.asm from config_ZETA_std.asm,
-then you would create a subdirectory in RomDsk called
-cfg_ZETA_wayne and copy all the files from cfg_ZETA_std to
-cfg_ZETA_wayne.
-
-3. Run the Build Process
-------------------------
-
-NOTE: The process described here is the more commonly
-used build script.  If you wish to use a makefile
-instead, refer to the comments in the makefile in
-the Source directory as an alternative to the
-process described here.
-
-The build involves running commands at the command
-prompt.  From a Command Prompt window, you will need
-to change to the high level directory for the build.
-Normally, you would be changing to the RomWBW directory
-unless you renamed it.
-
-First, you will need to build the components that are
-common to all configurations.  These components do not
-require any configuration.  To build these, use the
-following commands and ensure that they complete
-without error:
-
-	BuildZCPR-DJ
-	BuildApps2
-
-To run the main build and be prompted for required information,
-just enter "Build".  You will be prompted for the information
-described below and the build should run.  If an error is
-encountered, the build should stop and display an error
-in red text.
-
-If you immediately receive the error "the execution of 
-scripts is disabled on this system", then you will need to 
-change the PowerShell Execution-Polcy to "RemoteSigned".
-To do this, you need to right-click on FixPowerShell.cmd and
-choose "Run as Administrator" to make the change.  If is
-critical that you right-click and use "Run as Administrator"
-or the change will not work (you will get an error
-indicating "Access to the registry denied" if you fail to
-use "Run as Administrator".
-
-The build script will prompt you for the following information
-which you will need to provide (don't worry, it is simple):
-
-Platform:
-
-Respond with the name of the platform that you are targeting.
-It must be one of N8VEM, ZETA, N8, S2I, or S100.
-
-Configuration:
-
-Respond with the name of the configuration you wish to build.
-A list of all available configurations is displayed for your
-convenience.  For example, if you are building the provided
-ZETA_std configuration, just enter "std".  If you have created a
-custom configuration as described above, you would enter
-"wayne".
-
-ROM Size [512|1024]:
-
-Respond with either "512" for a 512KB ROM build or "1024" for a
-1MB ROM build.  Only the two choices are possible at this time.
-It is important that you choose a ROM size that is no larger than
-the szie of the ROM you will ultimately be burning.  This is 
-dependant on your hardware.
-
-At this point, the build should run and you will see output related
-to the assembler runs and some utility invocations.  Just review
-the output for any obvioius errors.  Normally, all errors will
-cause the build to stop immediately and display an error message
-in red.
-
-You will see some lines in the output indicating the amount of
-space variouis components have taken.  You should check these
-to make sure you do not see any negative numbers which would
-indicate that you have included too many features/drivers for
-the available memory space.  Here are examples of the lines
-showing the space used:
-
-	DATA space remaining: 39 bytes.
-	BOOT LOADER space remaining: 3503 bytes.
-	CBIOS space remaining: 161 bytes.
-	DBGMON space remaining: 860 bytes.
-	ROMX space remaining: 8191 bytes.
-	BOOT LOADER space remaining: 3503 bytes.
-
-4. Deploy the ROM
------------------
-
-If you look in the Output directory.  You should find the following files:
-
-     <config>.rom - binary ROM image to burn to EEPROM
-     <config>.sys - system image that can be written to the start of a
-                    disk to enable boot from disk functionality
-     <config>.com - executable version of the system image that can be
-                    copied via xmodem to a running system to test
-                    the build.
-
-The actual ROM image is the file ending in .rom.  It should be exactly
-512KB or 1MB depending on the ROM size you chose.  Simply burn the .rom
-image to your ROM and install it in your hardware.
-
-Specifying Build Options on Command Line
-----------------------------------------
-
-If you don't want to be prompted for the options to the "Build"
-command, you can specify the options right on the command line.
-
-For example:
-
-	Build ZETA std 512
-
-In this case, you will not be prompted.  This is useful if you
-wish to automate your build process.

 This file is a log of the work done to adapt the ZSDOS distribution to the N8VEM platforms under RomWBW.  I strongly recommend reviewing the zsdos.pdf file in the Doc directory.

 The remainder of this document details the changes I made as I went along.  In all cases, my goal was to keep the result as close to the original distribution as possible.  I started by copying all of the files from the distribution (contained in zsdos2.zip) into Support\ZSDOS.  From there I tested, modified, updated, and customized as documented below.  Finally, I cherry picked files that made sense to include on the ZSystem ROM disks.

-================================================================
-FDTST v3.1 for N8VEM DISKIO / DISKIO V3  / ZETA / DIDE / N8
-================================================================
-
-Updated JuLY 1, 2012
-by Wayne Warthen (wwarthen@gmail.com)
-
-Application to test the hardware functionality of the Floppy Disk
-Controller (FDC) on the ECB DISK I/O, DISK I/O V3, ZETA SBC, 
-Dual IDE w/ Floppy, or N8 board.
-
-The intent is to provide a testbed that allows direct testing
-of all possible media types and modes of access.  The application
-supports read, write, and format by sector, track, and disk as
-well as a random read/write test.
-
-The application supports access modes of polling, interrupt, 
-INT/WAIT, and DRQ/WAIT.  At present, it supports 3.5" media at DD (720KB) and
-HD (1.44MB) capacities.  It also now supports 5.25" media (720KB and 1.2MB)
-and 8" media (1.11MB) as well.   Additonal media will be added when I have
-time and access to required hardware.  Not all modes are supported
-on all platforms and some modes are experimental in all cases.
-
-In many ways this application is merely reinventing the wheel and
-performs functionality similer to existing applications, but I have
-not seen any other applications for DISK I/O that provide this range
-of functionality.
-
-While the application is now almost entirely new code, I would like to
-acknowledge that much was derived from the previous work of Andrew Lynch
-and Dan Werner.  I also want to credit Sergio Gimenez with testing the 5.25"
-drive support and Jim Harre with testing the 8" drive support.  Thanks!
-
-General Usage
--------------
-
-In general, usage is self explanatory.  The main menu allows you to set
-the unit, media, and mode to test.  These settings MUST match your
-situation.  Read, write, format, and verify functions are provided.  A sub-menu
-will allow you to choose sector, track, disk, or random tests.
-
-The verify function requires a little explanation.  It will take the contents
-of the buffer, save it, and compare it to the selected sectors.  So, you
-must ensure that the sectors to be verified already have been written
-with the same pattern as the buffer contains.  I typically init the buffer
-to a pattern, write the pattern to the entire disk, then verify the entire
-disk.
-
-Another submenu is provided for FDC commands.  This sub-menu allows you to
-send low-level commands directly to FDC.  You MUST know what you are doing
-to use this sub-menu.  For example, in order to read a sector using this
-sub-menu, you will need to perform specify, seek, sense int, and read 
-commands specifying correct values (nothing is value checked in this menu).
-
-Required Hardware/BIOS
-----------------------
-
-Of course, the starting point is one of the support hardware platforms.
-You need to start with either an N8VEM SBC, backplane, and ECB DISK I/O
-card or a Zeta SBC.  Additionally, a floppy drive connected via an
-appropriate cable:
-
-DISKIO - no twist in cable, drive unit 0/1 must be selected by jumper on drive
-ZETA - cable with twist, unit 0 after twist, unit 1 before twist
-DIDE/N8 - cable with twist, unit 0 before twist, unit 1 after twist
-
-
-It is preferable that the BIOS you use does not have DISK I/O support
-enabled since the application assumes it has complete control of the
-DISK I/O hardware.
-
-The DISK I/O should be jumpered as follows:
-
-J1: depends on use of interrupt modes (see interrupt modes below)
-J2: pins 1-2, & 3-4 jumpered
-J3: hardware dependent timing for DMA mode (see DMA modes below)
-J4: pins 2-3 jumpered
-J5: off
-J6: pins 2-3 jumpered
-J7: pins 2-3 jumpered
-J8: off
-J9: off
-J10: off
-J11: off
-J12: off
-
-Note that J1 can be left on even when not using interrupt modes.  As
-long as the BIOS is OK with it, that is fine.  Note also that J3 is
-only relevant for DMA modes, but also can be left in place when
-using other modes.
-
-The DISK I/O V3 should be jumpered at the default settings:
-
-JP2: 3-4
-JP3: 1-2 for int mode support, otherwise no jumper
-JP4: 1-2, 3-4
-JP5: 1-2
-JP6: 1-2
-JP7: 1-2, 3-4
-
-Zeta does not have any relevant jumper settings.
-
-DIDE should be jumpered as follows:
-
-K3 (DT/R or /RD): /RD
-P5 (bd ID): 1-2, 3-4 (for $20-$3F port range)
-
-There are no specific N8 jumper settings, but the default
-I/O range starting at $80 is assumed in the published code.
-
-
-Modes of Operation
-------------------
-
-You can select the following test modes.  Please refer to the chart
-that follows to determine which modes should work with combinations
-of Z80 CPU speed and media format.
-
-Polling: Traditional polled input/output.  Works well and very reliable
-including timeouts and good error recovery.  Also, the slowest performance
-which precludes it from being used with 1.44MB floppy on a 4MHz Z80.
-This is definitely the mode you want to get working before any others.
-It does not require J1 (interrupt enable) on DISK I/O and does not care about
-the setting of J3.
-
-Interrupt: Input/output is interrupt driven.  Works pretty well, but
-is not able to recover from some errors.  For example, if there is
-no disk in the drive, this mode will just hang until a disk is inserted.
-This mode REQUIRES that interrupts be enabled on the DISK I/O via
-jumper at J1.  On Zeta it requires the INT/NMI jumper be set for
-INT.  Mode not supported on DIDE or N8.  Some BIOS variants will not 
-handle interrupts during boot.
-
-Fast Interrupt: As above, but sacrifices additional reliability for
-faster operation.  This mode will allow a 1.44MB floppy to work
-with a 4MHz Z80 CPU.  However, if any errors occur (even a transient
-read error which is not unusual), this mode will hang.  As above
-you MUST have the appropriate jumpers for DISKIO and Zeta.  DIDE
-does not support this mode.
-
-INT/WAIT: Same as Fast Interrupt, but uses CPU wait instead of
-actual interrupt.  Subject to all the same issues as Fast
-Interrupt, but does not need J1 shorted.  J3 is irrelevant.
-This mode is available on only on DISKIO (and not DISKIO V3).
-
-DRQ/WAIT: Uses pseudo DMA to handle input/output.  Does not require that
-interrupts (J1) be enabled on the DISK I/O.  However, it is subject to
-all of the same reliability issues as "Fast Interrupt".  This
-mode is known to not work on N8VEM DISKIO!!!  It is included
-for testing only.  It is dependent on setting of J3.  This
-mode is NOT available on Zeta, DIDE, N8, or DISKIO V3.
-
-The chart below attempts to describe the combinations that
-work for me.  By far, the most reliable mode is Polling,
-but it requires 8MHz CPU for HD disks.

-Y = Yes, works
-N = No, does not work
-X = Experimental, probably won't work
-
-Tracing
--------
-
-Command/result activity to/from the FDC will be written out
-if the trace setting is changed from '00' to '01' in setup.
-Additionally, if a command failure is detected on any
-command, that specific comand and results are written
-regardless of the trace setting.
-
-The format of the line written is:
-<OPERATION>: <COMMAND BYTES> --> <RESULT BYTES> [<RESULT>]
-
-For example, this is the output of a normal read operation:
-READ: 46 01 00 00 01 02 09 1B FF --> 01 00 00 00 00 02 02 [OK]
-
-Please refer to the i8272 data sheet for information on the
-command and result bytes.
-
-Note that the sense interrupt command can return a non-OK
-result.  This is completely normal in some cases.  It is
-necessary to "poll" the drive for seek status using
-sense interrupt.  If there is nothing to report, then
-the result will be INVALID COMMAND.  Additionally,
-during a recalibrate operation, it may be necessary to
-issue the command twice because the command will only step
-the drive 77 times looking for track 0, but the head may be
-up to 80 tracks away.  In this case, the first recalibrate
-fails, but the second should succeed.  Here is what this
-would look like if trace is turned on:
-
-RECALIBRATE: 07 01 --> <EMPTY> [OK]
-SENSE INTERRUPT: 08 --> 80 [INVALID COMMAND]
-	...
-	...
-	...
-SENSE INTERRUPT: 08 --> 80 [INVALID COMMAND]
-SENSE INTERRUPT: 08 --> 71 00 [ABNORMAL TERMINATION]
-RECALIBRATE: 07 01 --> <EMPTY> [OK]
-SENSE INTERRUPT: 08 --> 21 00 [OK]
-
-Another example is when the FDC has just been reset.  In
-this case, you will see up to 4 disk change errors.  Again
-these are not a real problem and to be expected.
-
-When tracing is turned off, the application tries to be
-intelligent about error reporting.  The specific errors
-from sense interrupt documented above will be suppressed
-because they are not a real problem.  All other
-errors will be displayed.
-
-Error Handling
---------------
-
-There is no automated error retry logic.  This is very
-intentional since the point is to expose the controller
-and drive activity.  Any error detected will result in 
-a prompt to abort, retry, or continue.  Note that some
-number of errors is considered normal for this
-technology.  An occasional error would not necessarily
-be considered a problem.
-
-CPU Speed
----------
-
-I distribute the binary version of the application optimized for
-20MHz CPUs.  There is a configuration variable called CPUFREQ
-at the top of the source file.  Ideally, you should build
-with that set appropriately.  However, I have found that the
-default build setting of 20MHz seems to work for 4-20MHz CPUs.
-
-Interleave
-----------
-
-The format command now allows the specification of a sector
-interleave.  It is almost always the case that the optimal
-interleave will be 2 (meaning 2:1).
-
-360K Media
-----------
-
-The 360K media definition should work well for true 360K
-drives.  However, it will generally not work
-with 1.2M drives.  This is because these drives spin at 360RPM
-instead of the 300RPM speed of true 360K drives.  Additionally,
-1.2M drives are 80 tracks and 360K drives are 40 tracks and, so
-far, there is no mechanism in FDTST to "double step" as a way
-to use 40 track media in 80 track drives.
-
-With this said, it is possible to configure some 1.2M 5.25" drives
-to automatically spin down to 300RPM based on a density select
-signal (DENSEL).  This signal is asserted by FDTST for 360K
-media, so IF you have configured your drive to react to this
-signal correctly, you will be able to use the 360K media defintion.
-Most 1.2M 5.25" drives are NOT configured this way by default.
-TEAC drives are generally easy to modify and have been tested by
-the author and do work in this manner.  Note that this does not 
-address the issue of double stepping above; you will just be 
-using the first 40 of 80 tracks.
-
-Support
--------
-
-I am happy to answer questions as fast and well as I am able.
-Best contact is wwarthen@gmail.com or post something on the
-N8VEM Google Group https://groups.google.com/forum/#!forum/n8vem.
-
-Changes
--------
-
-WW 8/12/2011
-
-Removed call to pulse TC in the FDC initialization
-after determining that it periodically caused the FDC to write
-bad sectors.  I am mystified by this, but definitely found it
-to be true.  Will revisit at some point -- probably a timing
-issue between puslsing TC and whatever happens next.
-
-Non-DMA mode was being set incorrectly for FAST-DMA mode.
-It was set for non-DMA even though we were doing DMA.  It is
-interesting that it worked fine anyway.  Fixed it anyway.
-
-DIO_SETMEDIA was not clearing DCD_DSKRDY as it should.  Fixed.
-
-WW 8/26/2011: v1.1
-
-Added support for Zeta.  Note that INT/WAIT and DRQ/WAIT are
-not available on Zeta.  Note that Zeta provides the ability
-to perform a reset of the FDC independent of a full CPU
-reset.  This is VERY useful and the FDC is reset anytime
-a drive reset is required.
-
-Added INT/WAIT support.
-
-WW 8/28/2011: V1.2
-
-All changes in this version are Zeta specific.  Fixed FDC reset
-logic and motor status display for Zeta (code from Sergey).
-
-Modified Zeta disk change display to include it in the
-command output line.  This makes more sense because a command
-must be issued to select the desired drive first.  You can
-use the SENSE INT command id you want to check the disk
-change value at any time.  It will also be displayed with
-any other command output display.
-
-WW 9/1/2011: V1.3
-
-Added CPUFREQ configuration setting to tune
-delays based on cpu speed.  The build app
-is set for 8MHz which also seems to work well
-for 4MHz CPU's.  Faster CPU speeds will
-probably require tuning this setting.
-
-WW 9/5/2011: V1.4
-
-Changed the polling execution routines to utilize CPUFREQ
-variable to optimize timeout counter.  Most importantly,
-this should allow the use of faster CPUs (like 20MHz).
-
-WW 9/19/2011: V1.5
-
-Zeta changes only.  Added a call to FDC RESET after any
-command failure.  This solves an issue where the drive
-remains selected if a command error occurs.  Also
-added FDC RESET to FDC CONTROL menu.
-
-WW 10/7/2011: V2.0
-
-Added support for DIDE.  Only supports polling IO and it
-does not appear any other modes are possible given the
-hardware constraints.
-
-WW 10/13/2011: V2.1
-
-Modified to support N8.  N8 is essentially identical to
-Dual IDE. The only real change is the IO addresses.  In
-theory, I should be able to support true DMA on N8 and
-will work on that.
-
-WW 10/20/2011: v2.2
-
-I had some problems with the results being read were
-sometimes missing a byte.  Fixed this by taking a more
-strict approach to watching the MSR for the exact
-bits that are expected.
-
-WW 10/22/2011: V2.3
-
-After spending a few days trying to track down an
-intermittent data corruption issue with my Dual IDE
-board, I added a verify function.  This helped
-me isolate the problem very nicely (turned out to
-be interference from the bus monitor).
-
-WW 11/25/2011: V2.4
-
-Preliminary support for DISKIO V3.  Basically just
-assumed that it operates just like the Zeta.  Needs
-to be verified with real hardware as soon as I can.
-
-WW 1/9/2012: V2.5
-
-Modified program termination to use CP/M reset
-call so that a warm start is done and all
-drives are logged out.  This is important
-because media may have been formatted during
-the program execution.
-
-WW 2/6/2012: v2.6
-
-Added support for 5.25" drives as tested by
-Sergio.
-
-WW 4/5/2012: v2.7
-
-Added support for 8" drives as tested by
-Jim Harre.
-
-WW 4/6/2012: v2.7a
-
-Fixed issue with media selection menu to remove
-duplicate entries.
-
-WW 4/8/2012: v2.7b
-
-Corrected the handling of the density select
-signal.
-
-WW 5/22/2012: v2.8
-
-Added new media definitions (5.25", 320K)
-
-WW 6/1/2012: v2.9
-
-Added interleave capability on format
-
-WW 6/5/2012: v3.0
-
-Documentation cleanup
-
-WW 7/1/2012: v3.1
-
-Modified head load time (HLT) for 8" media based on
-YD-180 spec.  Now set to 50ms.

-                          http://sowerbutts.com/8bit/
-
-= Warning =
-
-FLASH4 has been tested and confirmed working on:
- * SBCv2
- * N8-2312
- * Mark IV SBC
-
-However it remains somewhat experimental. If it works for you, please let me
-know. If it breaks please also let me know so I can fix it! Until it is more
-widely tested please ensure you have some other means to reprogram your flash
-ROM before exclusively trusting FLASH4.
-
-
-= Introduction =
-
-FLASH4 is a CP/M program which can read, write and verify Flash ROM contents to
-or from an image file stored on a CP/M filesystem. It is intended for in-system
-programming of Flash ROM chips on N8VEM Z80 and Z180 systems.
-
-FLASH4 aims to support a range of Flash ROM chips. Ideally I would like to
-support all Flash ROM chips that are in use in Z80/Z180 N8VEM machines. If
-FLASH4 does not support your chip please let me know and I will try to add
-support.
-
-When writing to the Flash ROM chip, FLASH4 will only reprogram the sectors
-whose contents have changed. This helps to reduce wear on the flash memory,
-makes the reprogram operation faster, and reduces the risk of leaving the
-system unbootable if power fails during a reprogramming operation. FLASH4
-always performs a full verify operation after writing to the chip to confirm
-that the correct data has been loaded.
-
-FLASH4 is reasonably fast. Reprogramming and verifying every sector on a 512KB
-SST 39F040 chip takes 21 seconds on my Mark IV SBC, versus 45 seconds to
-perform the same task using a USB MiniPro TL866 EEPROM programmer under Linux
-on my PC. If only a subset of sectors require reprogramming FLASH4 will be
-even faster.
-
-FLASH4 works with binary ROM image files, it does not support Intel Hex format
-files. Hex files can be easily converted to or from binaries using "hex2bin" or
-the "srec_cat" program from SRecord:
-
-  $ srec_cat image.hex -intel -fill 0xFF 0 0x80000 -output image.bin -binary
-  $ srec_cat image.bin -binary -output image.hex -intel
-
-FLASH4 can use three different methods to access the Flash ROM chip. The best
-available method is determined automatically at run time. Alternatively you may
-provide a command-line option to force the use of a specific method.
-
-The first two methods use bank switching to map sections of the ROM into the
-CPU address space. FLASH4 will detect the presence of RomWBW or UNA BIOS and
-use the bank switching methods they provide.
-
-If neither RomWBW nor UNA BIOS is detected and the system has a Z180 CPU,
-FLASH4 will use the Z180 DMA engine to access the Flash ROM chip. This does not
-require any bank switching but it is slower and will not work on all platforms.
-
-Z180 DMA access requires the flash ROM to be linearly mapped into the lower
-region of physical memory, as it is on the Mark IV SBC. The N8-2312 has
-additional memory mapping hardware, consequently Z180 DMA access on the N8-2312
-is NOT SUPPORTED and if forced will corrupt the contents of RAM; use bank
-switched access instead.
-
-Z180 DMA access requires the Z180 CPU I/O base control register configured to
-locate the internal I/O addresses at 0x40 (ie ICR bits IOA7, IOA6 = 0, 1).
-
-
-= Usage =
-
-The three basic operations are:
-
-  FLASH4 WRITE filename [options]
-
-This will rewrite the flash ROM contents from the named file. The file size
-must exactly match the size of the ROM chip. After the write operation, a
-verify operation will be performed automatically.
-
-  FLASH4 VERIFY filename [options]
-
-This will read out the flash ROM contents and report if it matches the contents
-of the named file. The file size must exactly match the size of the ROM chip.
-
-  FLASH4 READ filename [options]
-
-This will read out the entire flash ROM contents and write it to the named
-file.
-
-If your ROM chip is larger than the image you wish to write, use the "/PARTIAL"
-(or "/P") command line option. To avoid accidentally flashing the wrong file,
-the image file must be an exact multiple of 32KB in length. The portion of the
-ROM not occupied by the image file is left either unmodified or erased.
-
-One of the following optional command line arguments may be specified at the
-end of the command line to force FLASH4 to use a particular method to access
-the flash ROM chip:
-
-  /ROMWBW
-  /UNABIOS
-  /Z180DMA
-
-If no option is specified FLASH4 attempts to determine the best available
-method automatically.
-
-
-= Supported chips and features =
-
-FLASH4 will interrogate your flash ROM chip to identify it automatically.
-FLASH4 assumes that you have a single flash ROM device and it is located at the
-bottom of the physical memory map.
-
-FLASH4 does not support setting or resetting the protection bits on individual
-sectors within Flash ROM devices. If your Flash ROM chip has protected sectors
-you will need to unprotect them by other means before FLASH4 can erase and
-reprogram them.
-
-AT29C series chips employ an optional "software data protection" feature. This
-is supported by FLASH4 and is left activated after programming the chip to
-prevent accidental reprogramming of sectors.
-
-The following chips are supported:
-
-  AT29F010
-  AT29F040
-  M29F010
-  M29F040
-  MX29F040
-  SST 39F010
-  SST 39F020
-  SST 39F040
-  AT29C512
-  AT29C040
-  AT29C010
-  AT29C020
-
-The following chips are supported but have unequal sector sizes; FLASH4 will
-only erase and reprogram the entire chip at once rather than its normal
-sector-by-sector operation:
-
-  AT49F001NT
-  AT49F001N
-  AT49F002N
-  AT49F002NT
-  AT49F040
-
-If you use a flash ROM chip that is not listed above please email me
-(will@sowerbutts.com) and I will try to add support for it.
-
-
-= Compiling =
-
-The software is written in a mix of C and assembler. It builds using the SDCC
-toolchain and the SRecord tools. A Makefile is provided to build the executable
-in Linux and I imagine it can be easily modified to build in Windows.
-
-You may need to adjust the path to the SDCC libraries in the Makefile if your
-sdcc installation is not in /usr/local

-Assembling the RomWBW firmware under Linux.
-
-Note: Updated on 6/25/2013 to eliminate the need for the separate Linux
-makefile.  The standard makefile now has conditionals to allow it to be
-used under Windows or Linux (I hope) --WW
-
-This method has been used under Ubuntu Linux and may have to be adapted for
-other distributions.  It is a bit more involved than the Windows procedure.
-
-What you need
-You will need the TASM assembler, make, dos2unix and cpmtools.
-
-The TASM assembler is shareware and the Linux version is only available as
-source code from the Author.  I found one bug during compiling version 3.2 for
-Ubuntu.  In /src/tasm.c change the reference CLK_TIC to CLOCKS_PER_SEC.
-After compiling install the tasm executable to /usr/local/bin and the table
-files to /usr/local/lib.  If you choose to place them somewhere else you will
-have to edit the "makefile.linux" file to suit.
-
-The make, dos2unix and cpmtools packages are found in the Linux repository and
-installed as for any other package.
-
-Before assembly
-Some changes need to be made to cater for the differences between Linux and the
-DOS/Windows environments.  The examples below refer to the /RomWBW/current
-directory, you'll have to allow for the stable or branches directories if used.
-These are all done from a terminal.  (: is end of the command prompt)
-
-1. Go to the RomWBW Source directory.e.g.
-:cd /n8vem/RomWBW/current/Source
-

+A Personal Note
+===============
+
+Somehow, I've managed to get by for the last 14 years using just ZCPR.
+But like some of you, I have fiddled with the standard ZCPR and
+modified it to suit my tastes.  As I added new commands or enriched old
+ones, I've always remained compatible with existing programs, all the
+BDOS replacements, and, most important of all, stayed within the 800H
+space allocation of the original Digital Research CCP.  Here are the
+fruits of my labors, I hope you enjoy this CCP replacement as much as I
+do.
+
+        Don Kirkpatrick
+        17595 S.W. Pheasant Lane

+        <Donald.C.Kirkpatrick@tek.com>
+
+
+Introduction
+============
+
+This console replacement is designed to run under CP/M 2.2 or any of
+the 2.2 BDOS replacements.  It requires a Z80 or better.  If you are
+running DRI's CCP or older versions of ZCPR1, this program is a
+significant improvement.  If you are running ZCPR3, CP/M 3.0, CP/M
+Plus, or MP/M, this will probably be a disappointment.
+
+If you are familiar with ZCPR3, you will recognize many of the
+enhancements here: comments on a command line, search path for the .com
+file, drive/user change with simple du:, CLEVEL3 command processing,
+proper SUBMIT file facility, and so on.  Nothing has been removed from
+DRI's CCP, only new features added.  AND IT ALL STILL FITS IN THE
+ORIGINAL 800H, THE SAME SPACE AS THE DIGITAL RESEARCH FIVE COMMAND
+CCP.
+
+Many of the standard commands have been enhanced.  For example, TYPE
+and LIST now have options to turn on or off page breaks.  Moreover, the
+console check for abort has been improved.
+
+Two commands have been added for use in submit files - SAK and BELL.
+These commands allow you to pause or ring the bell during submit file
+execution.
+
+Before you install this version of ZCPR onto your boot disks, try it by
+running it as a .com file.  Just edit the few customizing options and
+assemble the source.  After you decide it really is better, load it
+onto your boot track and make it your standard.  Complete instructions
+are located at the end of this document.
+
+The complete built-in command list is:
+
+    DIR - directory command enhanced to list optionally all user areas
+    REN - standard rename command
+    USER- move to new user number area on same drive
+    SAVE- save specified number of TPA pages or records in a file
+    TYPE- display a file on the console with optional page break pauses
+    LIST- print command plus optional form feed insertion
+    PAGE- send form feed to list device
+    ERA - standard file erase command
+    ERAQ- file erase with confirmation query at each file
+    DFU - set default user number for .com search path
+    BELL- send a bell character to the console
+    SAK - pause until a key is struck on the console (Strike Any Key)
+    SCL - toggle multiple commands per line (Single Command on a Line)
+    GET - load a file into the TPA at any specified location
+    JUMP- process command tail and execute program at specified address
+    GO  - process command tail and execute program loaded at 100H
+    PEEK- display hexadecimal byte string starting with specified address
+    POKE- load hexadecimal byte string starting with specified address
+    BOOT- execute BIOS cold boot routine
+
+
+Filename Processing
+===================
+
+The standard ZCPR3 du: drive/user file specification has been
+implemented.  Any filename can be in the du:fn.ft form.  For example:
+
+       A>era c4:junk*.*
+
+erases files on the C drive, user area 4 without leaving drive A user
+0.  When a user number is found in a filename, that user number is
+placed in S1 of the default FCB.  Bit 7 of S1 is set to inform the
+program using the FCB a user number was found.
+
+The * in an ambiguous file name has been improved.  Now a trailing *
+causes the remainder of the ambiguous name to be filled with '?', not
+just the fn field.  For example:
+
+       A>era c4:junk*
+
+is the same as the example above.  Previously, junk* was defined as
+'junk????.   '.  If you need the ft field blank, type 'junk*.'.  The
+question mark still works as a single character wild card.
+
+
+Command Line Processing
+=======================
+
+The  current user number is included as part of the command prompt for
+all non-zero user numbers.  The prompt is of the form du>, for example
+A2> or B10>.  If the SUPRES equate is true, the user number is
+suppressed for user 0 only.
+
+Multiple commands are typed on a single line separated by a command
+separator character.  Occasionally, you need to type the separator
+character in a command tail.  The SCL command toggles the multiple
+command enable.  The CMDCHR equate determines the command separator
+character.  A ';' has been chosen as the separator character in this
+distribution version.
+
+Comments are allowed on a command line.  When the comment separator
+character is encountered as the first character of a command, the
+remainder of the line is ignored.  The COMCHR equate determines the
+comment separator character.  A ';' has been chosen as the separator
+character in this distribution version.  Here is an example containing
+comments and multiple commands on a single line:
+
+   A>get 100 junk;peek 100;;this is a comment.
+   A>;this is also a comment.
+
+There exists a built-in search path for transient commands.  First, the
+current drive/user is searched.  Next, the current drive/default user
+is searched.  Last, drive A/default user is searched.  The DEFUSR
+equate determines the default user number, currently set to user 0 in
+this distribution version.  The default user is temporarily changed
+with the DFU command.  If a drive is specified in the transient
+command, the current and default user areas on the specified drive are
+searched.  If a user number is specified, that user area on the current
+and default drive are searched.  If both the drive and user number are
+specified, no search is performed.  The same drive/user area is never
+searched twice.
+
+Transient commands are always "called."  If a program terminates via a
+return rather than a warm boot, subsequent multiple commands on the
+command line are executed.  Any program exiting by a warm boot reloads
+ZCPR and the subsequent commands lost.
+
+A default command can be placed in the command buffer and control
+passed to ZCPR for processing.  The only thing required, besides
+placing the command in the buffer and jumping to CPRLOC, is to
+initialize the command character counter at the start of the buffer.
+The procedure is compatible with the original DRI CCP default command
+processing.  If ZCPR is entered at CPRLOC+3 jump, default command
+processing is suppressed.  Either way, register C must contain a valid
+drive/user, just like the original CCP.
+
+
+Submit File Processing
+======================
+
+A basic design choice had to be made in the design of ZCPR concerning
+the execution of submit files. The original CCP had a problem.  It
+ALWAYS looked for the $$$.SUB file on drive A and the submit program
+would place it on the current default drive.  When the you were logged
+onto drive B and you issued a submit command, the $$$.SUB was placed on
+drive B and not executed.
+
+After much debate it was decided to have ZCPR perform the same type of
+function as CCP (look for the $$$.SUB file on drive A), but the problem
+with SUBMIT.COM still exists.  Hence, RGF designed SuperSUB and RLC
+took his SuperSUB and designed SUB from it; both programs are set up to
+allow the selection at assembly time of creating the $$$.SUB on the
+default drive or on drive A.  If you don't have one of these newer
+submit programs, a procedure for patching the standard SUBMIT.COM has
+been included at the end.
+
+The fixed drive choice permits a submit file to contain a series of
+commands exactly as they would be entered from a CP/M console.  This
+permits things like:
+
+    A>dir
+    A>b:
+    B>dir
+
+to be executed, even though the currently default drive is changed
+during execution. If the $$$.SUB file were present on the default
+drive, the above series of commands would not work.  ZCPR would be
+looking for $$$.SUB on the default drive, and switching default drives
+without moving the $$$.SUB file would cause processing to abort.  Note
+that the same problem occurs if the user number of the $$$.SUB file is
+not predefined. ZCPR assumes that the $$$.SUB file is located on user 0
+of drive A.
+
+The trick of using the $ flag returned by the BDOS disk reset is used
+to speed the search for a $*.* file on drive A. This trick will not
+work if the $$$.SUB file were located on another drive.
+
+The '>' prompt character is replaced by a special character while a
+submit file is in execution.  The SPRMPT equate defines this special
+character, currently set to '$' in this distribution version.
+
+
+Command Syntax
+==============
+
+Multiple commands can be placed on one line.  If the comment character
+is encountered where a command should start, the rest of the line is
+ignored.  Any command can be renamed by editing the command table.
+Command names can be up to eight characters long and are terminated by
+bit 7 high.  If there is a conflict between an internal ZCPR command
+and a transient program of the same name, the internal command is
+executed.  Type the command with the du: included if the external
+transient command is the one desired.  Here is a complete alphabetized
+list of all the resident commands with their syntax:
+
+=============================================================================
+
+Command:  BELL
+
+Function: To ring terminal bell.
+
+Forms:    BELL
+
+Options:  None.
+
+Uses:     This command is designed to be placed in a submit file to
+          ring the bell to indicate significant checkpoints.
+
+=============================================================================
+
+Command:  BOOT
+
+Function: To execute BIOS cold boot routine.
+
+Forms:    BOOT
+
+Options:  REBOOT equate controls the inclusion/exclusion of this command.
+
+Uses:     Reboots the system without pushing the reset button.  The
+          cold boot entry point in the BIOS must be supported for this
+          command to work.
+
+=============================================================================
+
+Command:  DFU
+
+Function: To set the Default User Number for transient commands.
+
+Forms:    DFU <usrnum>
+
+Options:  DEFUSR equate defines the default user choice until this
+          command is entered.
+
+          NUMBASE equate defines the character that specifies a
+          hexadecimal number.  The distribution version is set to 'H'.
+
+Uses:     The default user area is searched after a transient command
+	  cannot be found in the current user area.  If the transient
+	  command still has not been found, the default user on the
+	  default drive is searched last.  The new default user number
+	  is in decimal, but hexadecimal numbers are entered by
+	  appending an 'H'.  The next warm boot will restore the
+	  original default user number.
+
+=============================================================================
+
+Command:  DIR
+
+Function: To display a directory listing of the files on a drive.
+
+Forms:    DIR <afn>       Display the DIR files
+          DIR <afn> S     Display the SYS files
+          DIR <afn> B     Display both DIR and SYS files
+          DIR <afn> A     Display both DIR and SYS files for all user areas
+
+Options:  TWOCOL equate controls the number of columns in the display.
+          Forty-column terminals are limited to two-column displays.
+
+          WIDE equate controls the spacing between the columns and
+          change the horizontal width of a directory display.
+
+          FENCE equate specifies the character separator between the
+          directory columns.
+
+          USRDLM equate specifies the character between the user number
+          and the filename.
+
+          USRFLG, SYSFLG, and SOFLG equates specify the command line
+          tail character that control the display of system and
+          non-system files.
+
+Uses:     Displays a directory listing of files in specific drive/user
+          area.
+
+=============================================================================
+
+Command:  ERA
+
+Function: To erase files.
+
+Forms:    ERA <afn>
+
+Options:  None.
+
+Uses:     Deletes files.  Names of erased files are displayed.
+
+=============================================================================
+
+Command:  ERAQ
+
+Function: To erase files with individual query.
+
+Forms:    ERAQ <afn>
+          <afn>? y          File erased
+          <afn>? <CR>       File not erased
+
+Options:  None.
+
+Uses:     Deletes a subset of a set of ambiguously specified files.
+          Any answer other than 'Y' (either case) will cause the file
+          to be skipped and not erased.
+
+=============================================================================
+
+Command:  GET
+
+Function: To load the specified file from disk to the specified address.
+
+Forms:    GET <hexadr> <ufn>
+
+Options:  None.
+
+Uses:     Loads a file into the TPA for patching purposes.  This command
+          searches for the specified file along the same search path as
+          the transient command loader.
+
+
+=============================================================================
+
+Command:  GO
+
+Function: To call the program in the TPA without loading from disk.
+
+Forms:    GO <command tail>
+
+Options:  None.
+
+Uses:     Most useful to rerun a program already loaded into the TPA.
+          Saves time and wear on disk drives.  The command tail is
+          entered exactly as it would appear if GO were replaced by the
+          program name.  Same as JUMP 100H, but more convenient,
+          especially when used with parameters for programs like STAT.
+
+=============================================================================
+
+Command:  JUMP
+
+Function: To call the program at a specified address.
+
+Forms:    JUMP <hexadr> <command tail>
+
+Options:  None.
+
+Uses:     Executes code not located at 100H.  For example, JUMP 0
+          warm boots.  The code must already reside at the specified
+          address.

+
+Command:  LIST
+
+Function: To print specified file on list device.
+-
+Forms:    LIST <ufn>      Print file
+          LIST <ufn> P    Print file without default paging
+
+Options:  NLINEP equate determines the number of lines per page.
+
+          FFKILL equate controls the suppression of form feeds before
+          printable text.
+
+          PGDFLG equate determines the command line tail character that
+          toggles the default form feed insertion every NLINEP lines.
+
+          NOSTAT equate controls the use of the BIOS list status call.
+
+Uses:     Prints files with/without pagination on LST: device.  A
+          listing is aborted by a console ^C.  Any submit file in
+          process is terminated and control is returned gracefully to
+          the console prompt.
+
+=============================================================================
+
+Command:  PAGE
+
+Function: To eject a page on list device via a form feed.
+
+Forms:    PAGE
+
+Options:  NOSTAT equate controls the use of the BIOS list status call.
+
+Uses:     Sends a form feed to the LST: device.  The page eject can
+	  be aborted by a console ^C if the system hangs because the
+	  printer is not ready.  If aborted, any submit file in process
+	  is terminated and control is returned gracefully to the
+	  console prompt.
+
+=============================================================================
+
+Command:  PEEK
+
+Function: To display hex values beginning at a specified address.
+
+Forms:    PEEK <hexadr> [<hexcnt>]
+
+Options:  None.
+
+Uses:     Displays hexadecimal values anywhere in the entire address
+          space.  The maximum value for <hexcnt> is 0FFH, but the
+          default <hexcnt> is 256.
+
+=============================================================================
+
+Command:  POKE
+
+Function: To poke a string of hex values into a set of consecutive
+          addresses.
+
+Forms:    POKE <hexadr> <hexval> [...<hexval>]
+
+Options:  None.
+
+Uses:     Modifies values anywhere in the entire address space.  Each
+          <hexval> represents one byte and is separated from the next
+          by a space.  The number of <hexval> are limited only by the
+          size of the command line buffer. The address is incremented
+          for each <hexval>.  Excellent for hand patching code.
+
+=============================================================================
+
+Command:  REN
+
+Function: To change the name of an existing file.
+
+Forms:    REN <newufn>=<oldufn>
+          REN <newufn>=<oldufn>     Existing <newufn>
+          Delete? y                 File deleted
+
+Options:  None.
+
+Uses:     Changes the names of files.  Any du: on <oldufn> is ignored;
+          the optional du: is on <newufn>.  If there already exists a
+          <newufn>, the console is queried for conformation.  Any
+          response except 'Y' (either case) aborts the command, kills
+          any submit file in process, and returns gracefully to the
+          command prompt.
+
+=============================================================================
+
+Command:  SAK
+
+Function: To pause until a key is struck.
+
+Forms:    SAK
+          ? <any key>
+
+Options:  None.
+
+Uses:     Pauses a submit file until a keystroke is entered.  Any
+	  character other than a ^C will resume execution.  A ^C kills
+	  the submit file, any commands remaining on the command the
+	  line are ignored, and control returns gracefully to the
+	  prompt.
+
+=============================================================================
+
+Command:  SAVE
+
+Function: To save the contents of TPA onto disk as a file.
+
+Forms:    SAVE <Number of Pages> <ufn>
+          SAVE <Number of Records> <ufn> R
+
+Options:  RECFLG equate determines the command tail character that
+          specifies records rather than pages.
+
+          NUMBASE equate defines the character that specifies a
+          hexadecimal number.  The distribution version is set to 'H'.
+
+Uses:     Saves the TPA to a file.  Records are 128 bytes long, pages
+	  are 256 bytes long.  Number of pages or records is in
+	  decimal, but a hexadecimal number is entered by appending an
+	  'H'.  Saved area begins at 100H.
+
+=============================================================================
+
+Command:  SCL
+
+Function: To force ZCPR to parse only a single command per line.
+
+Forms:    SCL
+
+Options:  MULTPL equate determines the inclusion/exclusion of this
+          command and whether or not multiple commands are allowed.
+
+          CMDCHR equate determines the character separating multiple
+          commands.
+
+Uses:     Some transient commands require the command separator in the
+          command tail.  This command turns off multiple command
+          parsing so the entire command tail is sent to the transient
+          program.  Multiple command format is reset at the next warm
+          boot. SCL toggles.
+
+=============================================================================
+
+Command:  TYPE
+
+Function: To display specified file on console.
+
+Forms:    TYPE <ufn>      Display file
+          TYPE <ufn> P    Display file without default paging
+
+Options:  NLINES equate determines the number of lines per screen.
+
+          FFKILL equate controls the suppression of form feeds before
+          printable text.
+
+          PGDFLG equate determines the command line tail character that
+          toggles the default form feed insertion every NLINEP lines.
+
+Uses:     Displays files with/without pagination on CON: device.  A
+          display is aborted by a console ^C.  If aborted, any submit
+          file in process terminates and control returns gracefully to
+          the console prompt.  When page breaks are enabled, any
+          console character except ^C will display the next page of
+          text.
+
+=============================================================================
+
+Command:  USER
+
+Function: To change current user number.
+
+Forms:    USER <usrnum>
+
+Options:  SUPRES equate controls the display of the user number in the
+          prompt when the user number is zero.
+
+          MAXUSR equate controls the maximum allowable user number.
+
+          NUMBASE equate defines the character that specifies a
+          hexadecimal number.  The distribution version is set to 'H'.
+
+Uses:     This command changes the current user number.  The new user
+          number is in decimal, but a hexadecimal number is entered by
+          appending an 'H'.  This command has been retained for
+          compatibility purposes only.  It is far easier to change
+          disk/user by typing du:.

+Error Messages
+==============
+
+If any error is encountered as a command line is being parsed, a
+message will be printed and, for serious errors, the remainder of the
+line is ignored.  Below is a complete list of all ZCPR error messages.
+Any error message encountered that is not on this list came from some
+program other than ZCPR.
+
+"?"
+
+   An error was detected in the command.  The an item on the command
+   line was not what was expected.  The command line is echoed up to
+   the position where the error was detected, as close as can be
+   determined, and the "?" printed.  Any commands remaining on the
+   command the line are ignored and any $$$.SUB file erased.
+
+"Full"
+
+   If ZCPR was attempting to load a transient program, one of two
+   things has gone wrong: either the program is so large that it won't
+   fit into the TPA or a read error was returned from the BDOS.  If
+   ZCPR was attempting to save a file, the BDOS write call returned
+   failure. Either the disk or the directory is full.  Any commands
+   remaining on the command line are ignored and any $$$.SUB file
+   erased.
+
+"No File"
+
+   No file could be found matching the filename specified in the
+   command.  This message is also be printed if the BDOS read command
+   returns failure.  If ZCPR was looking for a transient command, any
+   commands remaining on the command line are ignored and any $$$.SUB
+   file erased.
+
+"Name Error"
+
+   The specified filename has a user number larger than the allowable
+   maximum or an ambiguous filename was entered where only an
+   unambiguous filename is permitted.  Any commands remaining on the
+   command line are ignored and any $$$.SUB file erased.
+
+"Delete?"
+
+   Not really an error, but there already exists a file with the same
+   name as the requested new name in the REN command.  Any response
+   except 'Y' (either case) aborts the command, any commands remaining
+   on the command line are ignored, and any $$$.SUB file erased.
+
+"All?"
+
+   Not really an error, but a check to verify that all files on the
+   drive/user area are to be erased.  Any response except 'Y' (either
+   case) aborts the command and any commands remaining on the command
+   line are ignored.
+
+
+Installation Instructions
+=========================
+
+1) The first task is to determine the location of your BDOS because you
+   MUST set the P2DOS equate to this value.  If you do not know the
+   location of your BDOS, use ZCPRDEMO to find it.  If you do not
+   already have ZCPRDEMO.COM, assemble ZCPR with the TEST equate true
+   to make it.  A bootstrap loader will be included and you can run the
+   .com file.  This program assembles without errors using Microsoft's
+   M80/L80:
+
+   A>m80 =zcpr
+   A>l80 zcpr,zcprdemo/n/e
+
+   Other assemblers can be used, but ZCPR.MAC will probably require
+   editing to convert it to a form compatible.  The major decision in
+   converting is to determine how the .PHASE pseudo is to be handled.
+   Probably the best solution to the .PHASE is to generate a .hex
+   file and load it with an offset using DDT/SID/ZSID.  Consult the
+   "r" command in the DDT/SID/ZSID manaul.
+
+   Run ZCPRDEMO and peek at low memory:
+
+   A>zcprdemo
+   A<peek 0 10
+   0000 C3 03 F2 00 00 C3 06 E4 00 00 00 00 00 00 00 00
+   A<^C
+
+   Notice the prompt character has changed from a '>' to a '<'.  This
+   tells you the special debug version of ZCPR is running.  See the
+   debug section at the end for details.  Address 0 contains a jump 3
+   beyond the start of the BIOS and address 5 contains a jump 6 beyond
+   the start of the BDOS.
+
+   Be careful if you attempt to execute a transient program from
+   ZCPRDEMO.  Some transient programs, like NSWP, return rather than
+   warm boot when done. These programs don't know that ZCPRDEMO is at
+   address 8000H rather than just under the BDOS.  If they overwrite
+   ZCPRDEMO, then the return is to random code. Of course, this is not
+   a problem when ZCPR is installed just under the BDOS.
+
+2) You MUST edit the code to place your BDOS/P2DOS/Z80DOS/ZRDOS start
+   address in the P2DOS equate.  Set COMLD true (and TEST false if you
+   set it true in step 1 above) and make ZCPR.COM.  A bootstrap loader
+   will be included.
+
+   Assuming you successfully assemble it, just type "zcpr" to run it.
+   However, every time there is a warm boot, it will be  replaced by
+   the boot track CCP.  If you like what you see, place a copy on the
+   boot track to make it available all the time.
+
+3) Reassemble, this time with COMLD false to make ZCPRNBLD.COM (ZCPR
+   No Boot LoaDer).  
+
+4) Run SYSGEN to load a copy of the boot track into memory.
+
+   B>; Sample terminal session for integrating ZCPR
+   B>sysgen
+   SYSGEN VER 2.2
+   SOURCE DRIVE NAME (OR RETURN TO SKIP)a
+   SOURCE ON A, THEN TYPE RETURN  <cr>
+   FUNCTION COMPLETE
+   DESTINATION DRIVE NAME (OR RETURN TO REBOOT)  <cr>
+
+
+5) Run SAVE to save a track image to a file (eg: SAVE 32 BOOTFILE).
+   The number on the save command depends on the size of your boot
+   track loader; it can be as small as 31 and as large as 44.  If you
+   have extra disk space or are not sure, play it safe and use 44.
+
+   B>save 44 cpm56.com      <-- We now have a SYSGEN image of CP/M
+
+6) Find the location of the stock CCP by peeking at the boot file. It
+   is normally located at address 980H in the file. Using ZCPR:
+
+   B>zcpr                   <-- Reload zcpr.com version
+   B>get 100 cpm56.com
+
+   and search for the start of the console processor:
+
+   B>peek 980
+   0980 C3 xx xx C3 xx xx 7F 00 43 4F 50 59 52 49 47 48
+   0990 54 20 ...
+
+   If you don't find the start of the CCP at 980H, don't be
+   discouraged. It is there, but at a higher address.  Keep looking.
+
+7) When you find the location of the CCP, patch it with the new ZCPR
+   image.
+
+   B>get 980 zcprnbld.com
+
+8) Place the new file onto the boot track of a test disk, not your
+   original, using SYSGEN, and try it out.
+
+   B>sysgen
+   SYSGEN VER 2.2
+   SOURCE DRIVE NAME (OR RETURN TO SKIP) <cr>      <-- Use memory image
+   DESTINATION DRIVE NAME (OR RETURN TO REBOOT)b   <-- Load onto drive B
+   DESTINATION ON B, THEN TYPE RETURN <cr>
+   FUNCTION COMPLETE
+   DESTINATION DRIVE NAME (OR RETURN TO REBOOT) <cr>
+
+   You should now have a ZCPR system boot disk.  Notice you did all
+   your work on drive B so you wouldn't destroy the original.
+
+
+
+This may seem like a great number of steps, but each is only a single
+CP/M command line, total time is only 5 minutes or so after you get
+ZCPR to run as a .com file.
+
+
+Debugging ZCPR
+==============
+
+Special provisions have been make to ease the debugging of ZCPR.
+Setting the TEST equate true causes the assembler to build a version of
+ZCPR that executes in the TPA.  This allows the use of a debugger like
+DDT, ZSID, or Z8E to load and monitor execution.  To identify the debug
+version, the prompt character is changed from '>' to '<' when it runs.
+
+CPRLOC for the test version is 8000H.  A bootstrap loader is included
+at the beginning to move the image to this address.  Do not try to set
+a breakpoint until after the loader has moved ZCPR.  The easiest way to
+accomplish this is to single-step through the loader and then set your
+breakpoints.  Change the execution address to something lower if 8000H
+does not leave enough space for the debugger.
+
+A small amount of code is also added at the end of the debug version to
+compute the BIOS list status and cold boot entry points at run time.
+This permits the demo version to execute properly without setting the
+BDOS location equate.
+
+Patching SUBMIT.COM
+===================
+
+SUBMIT.COM is patched to run with ZCPR by the following procedure.
+This is recommended if the user does not have one of the newer public
+domain versions of submit.  This patch simply makes SUBMIT.COM always
+place the $$$.SUB file on drive A.  Illustrative terminal session
+follows:
+
+  A>get 100 submit.com;peek 5bb 2
+  05BB 00 24              <-- Patch is at 5BB Hex
+  A>poke 5bb 1            <-- Change 0 (default drive) to 1 (drive A)
+  A>peek 5b0 20           <-- Let's check just to make sure
+  05B0 00 00 00 00 00 00 30 30 31 20 24 01 24 24 24 20
+  05C0 20 20 20 20 53 55 42 00 00 00 1A 1A 1A 1A 1A 1A
+  A>save 5 newsubmt.com   <-- Save new SUBMIT.COM file
+
+Pretty simple, huh?

-' This program runs concurrently in two different COGs.
-'
-' Each COG's program has different values implanted for front-porch lines and
-' back-porch lines which surround the vertical sync pulse lines. This allows
-' timed interleaving of their active display signals during the visible portion
-' of the field scan. Also, they are differentiated so that one COG displays
-' even four-line groups while the other COG displays odd four-line groups.
-'
-' These COGs are launched in the PUB 'start' and are programmed to synchronize
-' their PLL-driven video circuits so that they can alternately prepare sets of
-' four scan lines and then display them. The COG-to-COG switchover is seemless
-' due to two things: exact synchronization of the two video circuits and the
-' fact that all COGs' driven output states get OR'd together, allowing one COG
-' to output lows during its preparatory state while the other COG effectively
-' drives the pins to create the visible and sync portions of its scan lines.
-' During non-visible scan lines, both COGs output together in unison.

-' This program runs concurrently in two different COGs.
-'
-' Each COG's program has different values implanted for front-porch lines and
-' back-porch lines which surround the vertical sync pulse lines. This allows
-' timed interleaving of their active display signals during the visible portion
-' of the field scan. Also, they are differentiated so that one COG displays
-' even four-line groups while the other COG displays odd four-line groups.
-'
-' These COGs are launched in the PUB 'start' and are programmed to synchronize
-' their PLL-driven video circuits so that they can alternately prepare sets of
-' four scan lines and then display them. The COG-to-COG switchover is seemless
-' due to two things: exact synchronization of the two video circuits and the
-' fact that all COGs' driven output states get OR'd together, allowing one COG
-' to output lows during its preparatory state while the other COG effectively
-' drives the pins to create the visible and sync portions of its scan lines.
-' During non-visible scan lines, both COGs output together in unison.
-'
-' COG RAM usage:	$000	= d0 - used to inc destination fields for indirection
-'		 $001-$050 = scanbuff - longs which hold 4 scan lines
