+## 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.

+# VGMPLAY
+
+This application will allow you to play Video Game Music files. VGM 
+files contain music samples from a range of different sound chips 
+that were used in arcade games, game consoles and personal computer 
+systems.
+
+Video Game Music files have a .VGM file extension and each file 
+contains an embedded header that identifies the hardware it is 
+intended for and also the title of the music.
+
+All RomWBW operating system boot disks include a selection of sound
+files in user area 3. Additional music files can be found at:
+
+[VGMRIPS website](https://vgmrips.net)
+
+[PROJECT2612 website](https://project2612.org/)
+
+Sound files are loaded into memory for playback, so the maximum size
+file that can be played is around 52Kb.
+
+Sound chips currently supported are:
+
+* AY-3-8190 (and equivalent YM2149)
+* YM2612 (and equivalent YM3848)
+* SN76489 (single chip mono and dual chip stereo)
+* YM2151 
+
+VGMPLAY supports playback of files with multiple combinations of these
+chips.
+
+## Syntax
+
+`VGMPLAY `*`<filename>`*
+
+*`<filename>`* is the name of a sound file ending in .VGM
+
+## Usage
+
+VGMPLAY does not automatically detect the hardware platform or sound
+hardware that you are using. This means a version customized for your
+system must be assembled before use.
+
+To play a sound file, just use the VGMPLAY command and specify the file
+to play after the command. So, for example, `VGMPLAY TEDDY` will load
+the TEDDY.VGM sound file into memory and begin playing it.
+
+Playback can be stopped by pressing a key. There may be a delay before
+playback stops.
+
+## Notes
+
+The default build configuration for VGMPLAY is:
+
+CPU speed: Autodetected
+
+| chip      | number  | port     | notes
+| --------- | ------- | -------- | ----------
+| AY-3-8910 |  1st    | 09ah     | stereo

+| YM2151    |  2nd    | 0cbh     | stereo
+
+Inconsistant, garbled or distorted playback can be an indication that
+your CPU clock speed is too high for your sound chip. In this case, if 
+your platform supports speed switching, then the CPUSPD application 
+can be used to reduce your processor speed.

+# WDATE
+
+`wdate` is a utility for CP/M systems that have Wayne Warthen's
+ROMWBW firmware. It reads or sets the real-time clock, using function
+calls in the BIOS. It should work on any RTC device that is supported by
+ROMWBW, including the internal interrupt-driven timer that is is available
+on some systems. 
+
+`wdate` differs from the `rtc.com` utility that is provided with the
+ROMWBW version of CP/M in that it only gets and sets the date/time. 
+`rtc.com` can also manipulate the nonvolatile RAM in certain clock
+devices, and modify the charge controller. However, `wdate` is (I would
+argue) easier to use, as it takes its input from the command line, which
+can be edited, and it's less fussy about the format. It doesn't require
+the date to be set if you only want to change the time, for example.
+ In addition, `wdate` has at least some error checking.
+
+`wdate` displays the day-of-week and month as English text, not 
+numbers. It calculates the day-of-week from the year, month, and day.
+RTC chips usually store a day-of-week value, but it's useless in this
+application for two reasons: first, the BIOS does not expose it. Second,
+there is no universally-accepted way to interpret it (which day does
+the week start on? Is '0' a valid day of the week?)
+
+## Syntax
+
+| `WDATE`
+| `WDATE ` *`<hr> <min>`*
+| `WDATE ` *`<hr> <min> <sec>`*
+| `WDATE ` *`<year> <month> <day> <hr> <min> <sec>`*
+
+## Usage
+
+    A> wdate
+    Saturday 27 May 13:14:39 2023
+
+With no arguments, displays the current date and time. 
+
+    A> wdate hr min
+
+With two arguments, sets the time in hours and minutes, without changing date
+or seconds
+

+
+With three arguments, sets the time in hours, minutes, and seconds, without
+changing date
+
+    A> wdate year month day hr min sec
+
+With six arguments, sets date and time. All numbers are one or two digits.  The
+two-digit year starts at 2000. 
+
+    A> wdate /?
+
+Show a summary of the command-line usage.
+
+## Notes
+
+I've tested this utility with the DS1302 clock board designed by Ed 
+Brindly, and on the interrupt-driven timer built into my Z180 board. 
+However, it does not interact with hardware, only BIOS; I would expect 
+it to work with other hardware.
+
+wdate checks for the non-existence of ROMWBW, and also for failing 
+operations on the RTC. It will display the terse "No RTC" message in 
+both cases.
+
+The ROMWBW functions that manipulate the date and time operate on BCD 
+numbers, as RTC chips themselves usually do. wdate works in decimal, so 
+that it can check that the user input makes sense. A substantial part of
+the program's code is taken up by number format conversion and range 
+checking.
+
+## Etymology
+
+The `WDATE` application was written and contributed by Kevin Boone.

+## Front Panel
+
+RomWBW supports the concept of a simple front panel.  The following 
+image is a conceptual view of such a front panel.  If your system has a 
+front panel, it should look similar to the [RomWBW Front Panel](#panel).
+
+![RomWBW Front Panel](Graphics/Panel){#panel width=50% }
+
+The LEDs in the top row of the panel are used for multiple purposes.
+They are initially used to display the progress of the
+system boot.  This may help in diagnosing a hardware or configuration
+issue in a system that does not progress far enough to display text
+output on the console.  The meaning of the LEDs is:
+
+|            |                              |
+|------------|------------------------------|
+| `O-------` | System Boot has started      |
+| `OO------` | Common RAM bank activated    |
+| `OOO-----` | HBIOS transitioned to RAM    |
+| `OOOO----` | Basic initialization done    |
+| `OOOOO---` | CPU detection complete       |
+| `OOOOOO--` | System timer configured      |
+| `OOOOOOO-` | Pre-console device init done |
+| `OOOOOOOO` | Console activation           |
+
+Once the system has booted, the LEDs are used to indicate disk device
+activity.  Each LED numbered 7-0 represents disk units 7-0.  As each
+disk device performs I/O, the LED will light.
+
+The second row of the front panel is composed of switches that allow
+you to control a few aspects of the system startup.
+
+The first two switches affect the device used as the console initially.
+Setting the CRT/Serial switch will cause the system to boot directly 
+to an attached CRT device (if available).  Setting the Pri/Sec switch 
+will cause the system to boot to the secondary Serial or CRT device 
+(depending on the setting of the first switch).
+
+The final six switches allow you to cause the system to automatically
+boot into a desired function.  The Auto/Menu switch must be set to
+enable this, otherwise the normal ROM Loader prompt will be used.
+If the Disk/ROM switch is not set, then you can use the last 3
+switches to select a ROM app to auto-start.  If the Disk/ROM switch is
+set, then the system will attempt a disk boot based on the following
+switches.  The Floppy/Hard switch can be used to boot to a Floppy or
+Hard Disk.  In either case, the first Floppy or Hard Disk will be used
+for the boot.  If a Hard Disk boot is selected, then the last three
+switches can be used to select any of the first 8 slices.
