-
-This directory ("Binary") is part of the RomWBW System Software 
-distribution archive.  Refer to the ReadMe.txt file in this 
-directory for more information on the overall contents of the 
-directory.
-
-RomWBW includes a set of disk images that are ready to copy onto
-a floppy or hard/CF/SD disk.  You can use your modern computer
-(Windows/Linux/Mac) to copy the disk image file onto your disk
-media.  The disk media will then be ready to use in your RomWBW
-System.
-
-WARNING: The hdnew_*.img disk images are part of a new disk
-format that is a work in progress.  Do not use these disk
-images without knowing exactly what you are doing!  The
-hd_*.img disk images continue to be the images you should
-be using under normal circumstances.
-
-A description of the disk images is provided later in this file.
-For more information on the creatioin of these images including
-instructions for customizing them or creating your own, refer to
-the ReadMe.txt file in the Source\Images directory.
-
-Installing Images
------------------
-
-The following instructions apply to Windows computers.  Alternatively,
-you can use the "dd" command on Linux or Mac.
-
-First of all, a MAJOR WARNING!!!!  The tools described below are 
-quite capable of obliterating your running Windows system drive.  Use 
-with extreme caution and make sure you have backups.
-
-To install a floppy image on floppy media, you can use the tool 
-called RaWriteWin.  This tool is included in the Tools directory of 
-the distribution. This tool will write your floppy image (fd_xxx.img) 
-to a floppy disk using a raw block transfer.  The tool is GUI based 
-and it's operation is self explanatory.
-
-To install a hard disk image on a CF card or SD card, you must have 
-the appropriate media card slot on your computer. If you do, you can 
-use the tool called Win32DiskImager. This tool is also included in 
-the Tools directory of the distribution.  It will write your 
-hard disk image (hd_xxx.img) to the designated media card.  This tool 
-is also GUI based and self explanatory.
-
-The use of the SIMH emulator is outside of the scope of this document.  
-However, if you use SIMH, you will find that you can attach the hard 
-disk images to the emulator with lines such as the following in your 
-SIMH configuration file:
-
-  | attach hdsk0 hd_cpm22.img
-  | set hdsk0 format=HDSK
-  | set hdsk0 geom=T:2048/N:256/S:512
-  | set hdsk0 wrtenb
-  
-Making Disk Images Bootable
----------------------------
-
-The Operating System disk images below are ready to boot by the
-RomWBW Boot Loader.  However, if you update your RomWBW ROM, then
-you should also update the system tracks of your bootable disk
-images.  You would use SYSCOPY to do this.  SYSCOPY can also be
-used to make a disk bootable if it is not already bootable.
-
-You would use a command like the following to make drive C bootable:
-
-  | B>SYSCOPY C:=CPM.SYS
-
-The system file to use depends on the operating system you are trying
-to boot from the slice you are initializing with SYSCOPY:
-
-  CP/M 2.2 - cpm.sys
-  ZSDOS 1.1 - zsys.sys
-  CP/M 3 - cpmldr.sys
-  ZPM3 - cpmldr.sys
-  
-Slices
-------
-
-A RomWBW CP/M filesystem is fixed at 8MB.  This is because it is the 
-largest size filesystem supported by all common CP/M variants. Since 
-all modern hard disks (including SD Cards and CF Cards) are much 
-larger than 8MB, RomWBW supports the concept of "slices".  This 
-simply means that you can concatenate multiple CP/M filesystems (up 
-to 256 of them) on a single physical hard disk and RomWBW will allow 
-you to assign drive letters to them and treat them as multiple 
-independent CP/M drives.
-
-With the exception of the hd_combo image, each of the disk images
-includes a single CP/M file system (i.e., a single slice).  However,
-you can easily create a multi-slice disk image by merely concatenating 
-multiple images together.  For example, if you wanted to create a 2 
-slice disk image that has ZSDOS in the first slice and Wordstar in 
-the second slice, you could use the following command from a Windows 
-command prompt:
-
-  | C:\RomWBW\Binary>copy /b hd_zsdos.img + hd_ws.img hd_multi.img
-
-You can now write hd_multi.img onto your SD or CF Card and you will 
-have ZSDOS in the first slice and Wordstar in the second slice.
-
-The hd_combo disk image is an example of this.  It contains several
-slices in one image file.  The contents of this special disk image
-are described below.
-
-The concept of slices applies ONLY to hard disks.  Floppy disks are 
-not large enough to support multiple slices.
-
-Disk Image Contents
--------------------
-
-What follows is a brief description of the contents of the
-disk images automatically provided in the RomWBW distribution.
-Note that all of the OS images include the RomWBW custom
-support apps.
-
-cpm22 - DRI CP/M 2.2 (Bootable Floppy and Hard Disk)
-
-  Standard DRI CP/M 2.2 distribution files along with a few commonly
-  used utilities.
-
-zsdos - ZCPR1 + ZSDOS 1.1 (Bootable Floppy and Hard Disk)
-
-  Contains ZCPR1 and ZSDOS 1.1.  This is roughly equivalent to the
-  ROM boot contents, but provides a full set of the applications
-  and related files that would not all fit on the ROM drive.
-
-nzcom - NZCOM (Bootable Floppy and Hard Disk)
-
-  Standard NZCOM distribution.  Note that you will need to run the
-  NZCOM setup before this will run properly.  You will need
-  to refer to the NZCOM documentation.  
-
-cpm3 - DRI CP/M3 (Bootable Floppy and Hard Disk)
-
-  Standard DRI CP/M 3 adaptation for RomWBW that is ready to run.
-  It can be started by running CPMLDR.
-
-zpm3 - ZPM3 (Bootable Floppy and Hard Disk)
-
-  Simeon Cran's ZCPR 3 compatible OS for CP/M 3 adapted for RomWBW and 
-  ready to run.  It can be started by running CPMLDR (which seems 
-  wrong, but ZPMLDR is somewhat broken).
-
-ws4 - WordStar 4 (Floppy and Hard Disk)
-
-  Micropro Wordstar 4 full distribution.  This image is not bootable
-  and is intended to be added as an additional slice to an OS image.
-
-bp - BPBIOS (Hard Disk only)
-
-  Adaptation of BPBIOS for RomWBW.  This is NOT complete and NOT
-  useable in it's current state.
-
-combo - Multi-Boot Combination (Bootable Hard Disk)
-
-  A pre-created combo image that contains the following slices.  The
-  slices are identical to the individual images listed above.
-
-    Slice 0: cpm22 (bootable)
-    Slice 1: zsdos (bootable)
-    Slice 2: nzcom (bootable)
-    Slice 3: cpm3 (bootable)
-    Slice 4: zpm3 (bootable)
-    Slice 5: ws4 (not bootable)

-***********************************************************************
-
-This directory ("Binary") is part of the RomWBW System Software
-distribution archive.  Refer to the ReadMe.txt file in this
-directory for more information on the overall contents of the
-directory.
-
-When distributed, RomWBW contains a set of pre-built ROM images that
-are ready to program onto the EEPROM of any of the Z80/Z180 based
-RetroBrew Computers CPU boards.  Additionally, any custom built ROM
-images will be placed in this directory.
-
-All of the pre-built ROM images are 512KB.  This size is compatible
-with all of the Z80/Z180 systems.  Some systems can accept different
-size ROM images.  Creating alternative sizes requires a custom ROM
-build (see ReadMe.txt in the Source directory).
-
-It is critical that the right ROM Imgae be selected for the target
-platform being used.  The table below indicates the correct ROM
-image to use for each platform:
-
-	SBC V1/V2	SBC_std.rom
-	SBC SimH	SBC_simh.rom
-	Zeta V1		ZETA_std.rom
-	Zeta V2		ZETA2_std.rom
-	N8		N8_std.rom
-	Mark IV		MK4_std.rom
-	RC2014 w/ Z80	RCZ80_std.rom
-	RC2014 w/ Z180	RCZ180_nat.rom	(native Z180 memory addressing)
-	RC2014 w/ Z180	RCZ180_ext.rom	(external 512K RAM/ROM module)
-	SC-series	SC126, SC130, SC131
-	Easy Z80	EZZ180_std.rom
-	Dyno		DYNO_std.rom
-
-You will find there is one additional ROM image called
-"UNA_std.rom". This ROM image is an UNA-based RomWBW ROM image.  As
-such, this ROM image can be used on any Z80/Z180 platform supported
-by John Coffman's UNA BIOS.  Refer to RetroBrew Computers Wiki for
-more information on UNA hardware support.
-
-For each of the ROM Images (".rom"), there are corresponding files
-with the extensions of ".com" and ".img".  The .com variant can be
-copied to a functional RomWBW-based system and executed like a
-normal application under CP/M or Z-System. This will load the new
-ROM on-the-fly.  It is an excellent way to test a ROM Image before
-actually burning it.  Similarly, the .img files can be loaded using
-the UNA FAT loader for testing.
-
-All of the standard ROM Images are configured for:
- - 512KB ROM Disk
- - 512KB RAM Disk
- - 38.4Kbps baud serial console (*)
- - Auto-discovery of all serial ports
-
-* RC2014 and Stephen Cousins' kits run at 115,200Kbps baud
-
-All hard disk type devices (IDE, PPIDE, CF Card, SD Card) will be
-automatically assigned at least two drive letters per device.  The
-drive letters will refer to the first 2 slices of the device. The
-ASSIGN command can be used to display and reassign drives to disk
-devices and slices as desired.
-
-Standard ROM Image Notes
-------------------------
-
-The standard ROM images will detect and install support for certain
-devices and peripherals that are on-board or frequently used with
-each platform as documented below.  If the device or peripheral is
-not detected at boot, the ROM will simply bypass support
-appropriately.
-
-SBC (SBC_std.rom):
- - CPU speed is detected at startup
- - Console on onboard UART serial port at 38400 baud
- - Includes support for PPIDE/CF Card(s) connected to on-board
-   parallel port.
- - Includes support for CVDU and VGA3 boards.  If detected at
-   startup, support for video and keyboard is installed
-   including VT-100/ANSI terminal emulation.
- - Auto detects DiskIO v3 floppy disk controller and installs
-   support for two attached 3.5" floppy disks if found
- - Auto-detects PropIO or PropIO V2 and installs associated
-   video, keyboard and SD Card support if present.
- - If PropIO, PropIO V2, CVDU, or VGA hardware is detected,
-   initial console output is determined by JP2.  If JP2 is
-   shorted, console will go to on-board serial port, if JP2
-   is open, console will go to the detected video and keyboard
-   ports.
- - SBC V1 has a known race condition in the bank switching
-   circuit which is likely to cause system instability.  SBC
-   V2 does not have this issue.
-
-SBC (SBC_simh.rom):
- - SBC variant customized to run under SimH
- - Implments two emulated SimH hard disk images

-   if found
- - Auto detects on-board floppy disk controller and installs
-   support for one attached 3.5" floppy disk if found
- - Auto-detects ParPortProp and includes support for it if it
-   is attached.
- - If ParPortProp is installed, initial console output is
-   determined by JP1.  If JP1 is shorted, console will go to
-   on-board serial port, if JP1 is open, console will go to
-   ParPortProp video and keyboard ports.
-
-ZETA2 (ZETA2_std.rom):
- - CPU speed is detected at startup
- - Console on onboard UART serial port at 38400 baud

-   is attached.
- - Uses CTC to generate periodic timer interrupts.
- - If ParPortProp is installed, initial console output is
-   determined by JP1.  If JP1 is shorted, console will go to
-   on-board serial port, if JP1 is open, console will go to
-   ParPortProp video and keyboard ports.
-
-N8 (N8_std.rom):
- - CPU speed is detected at startup
- - Console on Z180 onboard primary ASCI serial port at 38400 baud

+# Contributing to RomWBW
+
+> **WARNING**: The `dev` branch of RomWBW has been deprecated as of v3.4.  All Pull Requests should now target the `master` branch.
+
+Contributions of all kinds to RomWBW are welcomed and greatly appreciated.
+
+- Reporting bug(s) and suggesting new feature(s)
+- Discussing the current state of the code
+- Submitting a fixes and enhancements
+
+## RomWBW GitHub Repository
+
+The [RomWBW GitHub Repository](https://github.com/wwarthen/RomWBW) is the primary location for developing, supporting, and distributing RomWBW.  Although input is gladly accepted from almost any channel, the GitHub Repository is preferred.
+
+- Use **Issues** to report bugs, request enhancements, or ask usage questions.
+- Use **Discussions** to interact with others
+- Use **Pull Requests** to submit content (code, documentation, etc.)
+
+## Submitting Content
+
+This RomWBW Project uses the standard [GitHub Flow](https://docs.github.com/en/get-started/quickstart/github-flow).  Submission of content changes (including code) are ideally done via Pull Requests.
+
+- Submitters are advised to contact [Wayne Warthen](mailto:wwarthen@gmail.com) or start a GitHub Discussion prior to starting any significant work.  This is simply to ensure that submissions are consistent
+  with the overall goals and intentions of RomWBW.
+- All submissions should be based on the `master` branch.  To create your submission, fork the RomWBW repository and create your branch from `master`.  Make (and test) your changes in your personal fork.
+- Please update relevant documentation and the `ChangeLog` found in the `Doc` folder.
+- You are encouraged to comment your submissions to ensure your work is properly attributed.
+- When ready, submit a Pull Request to merge your forked branch into the RomWBW master branch.
+
+## Coding Style
+
+Due to the nature of the project, you will find a variety of coding styles.  When making changes to existing code, please try to be consistent with the existing coding style.  You may not like the current style, but no one likes mixed styles
+in one file/module.
+
+Be careful with white space.  RomWBW is primarily assembly langauge code.  The use of tab stops at every 8 characters is pretty standard for assembler.  If you use something else, then your code will look odd when viewed by others.
+
+In most cases, the use of `<cr><lf>` line endings is preferred.  This is standard for the operating systems of the era that RomWBW provides.  Also note that CP/M text files should end with a ctrl-Z (0x1A).  This is not magically added by the
+tools that generate the disk images.
+
+## License
+
+RomWBW is licensed under GPLv3.  When you submit code changes, your submissions are understood to be under the same [GPLv3 License](https://www.gnu.org/licenses/gpl-3.0.html) that covers the project.

+# RomWBW HBIOS CP/M FAT Utility ("FAT.COM")
+
+Author: Wayne Warthen \
+Updated: 6-Jan-2024
+
+This application allows copying files between CP/M filesystems and FAT 
+filesystems (DOS, Windows, Mac, Linux, etc.).  The application runs on 
+RomWBW hosted CP/M (and compatible) operating systems. The application 
+also has limited file management capabilities on FAT filesystems 
+including directory listing, renaming, deleting, and sub-directory 
+creation.
+
+### Usage:
+
+```
+  FAT DIR <path>
+  FAT COPY <src> <dst>
+  FAT REN <from> <to>
+  FAT DEL <path>[<file>|<dir>]
+  FAT MD <path>
+  FAT FORMAT <drv>
+```
+
+  CP/M filespec: \<d\>:FILENAME.EXT (\<d\> is CP/M drive letter A-P) \
+  FAT filespec:  \<u\>:/DIR/FILENAME.EXT (\<u\> is disk unit #)
+
+### Notes:
+
+ - Partitioned or non-partitioned media is handled automatically.
+   A floppy drive is a good example of a non-partitioned FAT
+   filesystem and will be recognized.  Larger media will typically
+   have a partition table which will be recognized by the
+   application to find the FAT filesystem.
+   
+ - Although RomWBW-style CP/M media does not know anything about
+   partition tables, it is entirely possible to have media that
+   has both CP/M and FAT file systems on it.  This is accomplished
+   by creating a FAT filesystem on the media that starts on a track
+   beyond the last track used by CP/M.  Each CP/M slice can occupy
+   up to 8MB.  So, make sure to start your FAT partition beyond
+   (slice count) * 9MB.
+
+ - The application infers whether you are attempting to reference
+   a FAT or CP/M filesystem via the drive specifier (char before ':').
+   A numeric drive character specifies the HBIOS disk unit number
+   for FAT access.  An alpha (A-P) character indicates a CP/M
+   file system access targeting the specified drive letter.  If there
+   is no drive character specified, the current CP/M filesystem and
+   current CP/M drive is assumed.  For example:
+   
+   `2:README.TXT` refers to FAT file README.TXT on disk unit #2 \
+   `C:README.TXT` refers to CP/M file README.TXT on CP/M drive C: \
+   `README.TXT` refers to CP/M file README.TXT on current CP/M drive
+   
+ - FAT files with SYS, HIDDEN, or R/O attributes are not given
+   any special treatment.  Such files are found and processed
+   like any other file.  However, any attempt to write to a
+   read-only file will fail and the application will abort.
+ 
+ - It is not currently possible to reference CP/M user areas other
+   than the current user.  To copy files to alternate user areas,
+   you must switch to the desired user number first or use an
+   additional step to copy the file to the desired user area.
+   
+ - Accessing FAT filesystems on a floppy requires the use of
+   RomWBW HBIOS v2.9.1-pre.13 or greater.
+
+ - Only the first 8 RomWBW disk units (0-7) can be referenced.
+   
+ - Files written are not verified.
+ 
+ - Wildcard matching in FAT filesystems is a bit unusual as
+   implemented by FatFs.  See FatFs documentation.
+
+### License:
+
+  GNU GPLv3 (see file LICENSE.txt)
+
+### Build Notes:
+
+ - Source is maintained on GitHub at <https://github.com/wwarthen/FAT>.
+
+ - Application is based on FatFs.  FatFs source is included.  See
+   <http://elm-chan.org/fsw/ff/>.
+
+ - SDCC compiler v4.3 or greater is required to build.  New calling
+   conventions introduced in v4.3 are assumed.
+
+ - See Build.cmd for sample build script under Windows.  References
+   to SDCC must be updated for your environment.
+   
+ - Note that ff.c (core FatFs code) generates quite a few compiler
+   warnings (all appear to be benign).
+
+### To Do:
+
+ - Allow ^C to abort any operation in progress.
+ 
+ - Allow referencing more than the first 8 RomWBW disk units.
+ 
+ - Handle wildcards in destination, e.g.:
+
+   `FAT REN 2:/*.TXT 2:/*.BAK`
+ 
+ - Do something intelligent with R/O and SYS file attributes
+ 
+ - Support UNA
