+# 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-May-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.
+
+ - 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.
+
+### 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

-   
-   "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 only 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.
-   
- - Files written are not verified.
- 
- - Wildcard matching in FAT filesystems is a bit unusual as
-   implemented by FatFs.  See FatFs documentation.
-
-BUILD NOTES:
- - Source is maintained on GitHub at https://github.com/wwarthen/FAT
-
- - Application is based on FatFs.  FatFs source is included.
-
- - SDCC compiler is required to build (v4.0.0 known working).
-
- - ZX CP/M emulator is required to build (from RomWBW distribution).
-
- - See Build.cmd for sample build script under Windows.  References
-   to SDCC and ZX 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.
- 
- - Handle wildcards in destination, e.g.:
-     "FAT REN 2:/*.TXT 2:/*.BAK"
- 
- - Do something intelligent with R/O and SYS files on FAT
- 
- - Support UNA
-
