+INTTEST
+=======
+
+RomWBW includes an API allowing applications to "hook" interrupts.
+The `INTTEST` utility allows you to test this functionality.
+
+
+** Syntax **
+
+`INTTEST`
+
+
+** Usage **
+
+`INTTEST` is an interactive application.  At startup, it will display
+a list of the interrupt vector slots in your system along with the
+current vector address for each of them.
+
+It then prompts you to enter the slot number (in hex) of a vector to
+hook.  After entering this, the application will watch the hooked
+vector and countdown from 0xFF to 0x00 as interrupts are noted.
+
+When the counter reaches 0x00, the interrupt is unhooked and the
+application terminates.  The application can also be terminated by
+pressing <esc>.
+
+
+** Notes **
+
+If your system is running without interrupts active, the application
+will terminate immediately.
+
+All slots have vectors even if the corresponding interrupt is not
+doing anything.  In this case, the vector is pointing to the "bad
+interrupt" handler.
+
+If you hook a vector that is not receiving any interrupts, the
+down-counter will not do anything.
+
+
+** Etymology* *
+
+The `INTTEST` command is an original product and the source code is
+provided in the RomWBW distribution.

+# RomWBW Release Notes
+
+This file contains information useful to those upgrading to a new
+release of RomWBW.
+
+## All Versions
+
+- **Please** review the "Upgrading" Section of the RomWBW User Guide.
+
+- The RomWBW ROM and the RomWBW disk images are intended to be a
+  matched set.  After upgrading your ROM, it is important to update
+  the OS boot tracks of your disks as well as the RomWBW-specific
+  applications.  This is discussed in the "Upgrading" section of the
+  RomWBW User Guide.
+
+## Version 3.5
+
+### Upgrade Notes
+
+- RomWBW is now more strict with respect to hard disk partition
+  tables.  If your hard disk media was created using any of the
+  pre-built disk image files, this will **not** affect you.  Otherwise,
+  you may find you are unable to access slices beyond the first
+  slice.  If so, use `FDISK80` to reset the partition table on the
+  disk.  This will restore normal access to all slices.  **Only** do
+  this if you are having an issue.
+
+- For those building custom ROMs that are overriding `DEFSERCFG`, note 
+  that this setting has been moved to a `#DEFINE` instead of an equate 
+  (`.SET` or `.EQU`).  You will find this `#DEFINE` at the top of all
+  standard config files.  You will need to change your setting to a
+  `#DEFINE` at the top of your config file and remove any `.SET` or
+  `.EQU` lines for `DEFSERCFG`.
+
+- Combining config settings `AUTOCON` and `VDAEMU_SERKBD` causes issues
+  at the boot loader prompt.  So, all config files have been changed to
+  consistently enable `AUTOCON` and disable `VDAEMU_SERKBD` (`$FF`).  If
+  are want to use `VDAEMU_SERKBD`, you need to set it in your config
+  file as well as disabling AUTOCON.
+  
+### New Features
+
+- RC2014 Front Panel and LCD Screen support.
+
+- Console "takeover" support at Boot Loader prompt by pressing the
+  <space> key twice on an alternate console device.
+
+- Cowgol disk image based on the work of Ladislau Szilagyi.
+
+- TMS video is automatically reset after an OS warm boot which
+  allows OS to recover from applications that reprogram the TMS
+  video display controller.
+
+- Implemented "application" RAM banks that can be discovered via
+  the HBIOS API.
+
+- Documentation improvements (Mark Pruden), including:
+
+  - Reorganization into multiple directories.
+  - Improved Disk Management section in User Guide.
+  - Overhaul of Disk Catalog.
+  
+- Disk image for Z3PLUS (Mark Pruden).
+
+- `REBOOT` application added (Martin R).  Also, reboot capability
+  added to `CPUSPD` utility.
+
+- `COPYSL` slice copy application (Mark Pruden).
+
+- Improved disk slice management and protection (Mark Pruden).
+
+- Initial NVRAM configuration support (Mark Pruden).
+
+- Enhancements to ASSIGN command to automatically assign drives
+  (Mark Pruden).
+
+
+### New Hardware Support
+
+- NABU w/ RomWBW Option Board.
+
+- EF9345 video display controller driver (Laszlo Szolnoki).
+
+- Duodyne Disk I/O (CP/NET) and Media boards.
+
+- PS/2 keyboard interface on RCBus systems.
+
+- S100 FPGA-based Z80 including console, SD Cards, and RTC.
+
+- Support for 16C550-family UART support on additional platforms.
+
+- Genesis STD Bus Z180 platform (Doug Jackson).
+
+- Support for Dinoboard eZ80 CPU board provided by Dean Netherton.
+
+- Added interrupt support to PS/2 keyboard driver by Phil Summers.

 A dynamic disk drive letter assignment mechanism allows mapping
 operating system drive letters to any available disk media.
 Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.)
 support the use of multiple slices (up to 256 per device). Each slice
 contains a complete CP/M filesystem and can be mapped independently to
 any drive letter. This overcomes the inherent size limitations in legacy

+## ROM Distribution
 
 The [RomWBW Repository](https://github.com/wwarthen/RomWBW)
 (<https://github.com/wwarthen/RomWBW>) on GitHub is the official
-distribution location for all project source and documentation. The
-fully-built distribution releases are available on the [RomWBW Releases
-Page](https://github.com/wwarthen/RomWBW/releases)
-(<https://github.com/wwarthen/RomWBW/releases>) of the repository. On

+
+RomWBW is distributed as both source code and pre-built ROM and disk

+
+The pre-built ROM images distributed with RomWBW are based on the

+file describing the contents in detail. In summary, these directories
+are:
+
+| **Directory** | **Description** |
+|----|----|
+| **Binary** | The final output files of the build process are placed here. Most importantly, the ROM images with the file names ending in “.rom” and disk images ending in .img. |
+| **Doc** | Contains various detailed documentation, both RomWBW specifically as well as the operating systems and applications. |
+| **Source** | Contains the source code files used to build the software and ROM images. |

+By design, RomWBW isolates all of the hardware specific functions in the

 This application allows copying files between CP/M filesystems and FAT 
 filesystems (DOS, Windows, Mac, Linux, etc.).  The application runs on 
@@ -72,6 +72,38 @@ creation.
  - Wildcard matching in FAT filesystems is a bit unusual as
    implemented by FatFs.  See FatFs documentation.
 
+ - The `FAT FORMAT` command will not perform a physical format on
+   floppy disks.  You must use FDU to do this prior to using
+   `FAT FORMAT`.
+
+ - Formatting (`FAT FORMAT`) of floppies does not work well.  The    
+   underlying FatFs library uses some non-standard fields.  The 
+   resulting floppy may or may not be useable on other systems.  It is 
+   best to format a FAT floppy on a Windows or DOS system.  You should 
+   have no problems copying files to/from such a floppy using `FAT`.
+
+### Known Issues
+
+ - CP/M (and workalike) OSes have significant restrictions on filename
+   characters.  The FAT application will block any attempt to create a
+   file on the CP/M filesystem containing any of these prohibited
+   characters:
+
+|         `< > . , ; : ? * [ ] |/ \`
+
+   The operation will be aborted with "`Error: Invalid Path Name`" if such
+   a filename character is encountered.
+
+   Since MS-DOS does allow some of these characters, you can have
+   issues when copying files from MS-DOS to CP/M if the MS-DOS filenames
+   use these characters.  Unfortunately, FAT is not yet smart enough to
+   substitute illegal characters with legal ones.  So, you will need to
+   clean the filenames before trying to copy them to CP/M.
+
+ - The FAT application does try to detect the scenario where you are
+   copying a file to itself.  However, this detection is not perfect and
+   can corrupt a file if it occurs.  Be careful to avoid this.
