-***********************************************************************
-
-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)

-Partitioning of RomWBW media is **only** required if you want to add a

+

+Since MS-DOS does allow some of these characters, you can have

+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.

+# 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
+| AY-3-8910 |  2nd    | not set  | stereo
+| YM2612    |  1st    | 0c0h     | stereo
+| YM2612    |  2nd    | 0c4h     | stereo
+| SN76489   |  1st    | 0c8h     | mono/left
+| SN76489   |  2nd    | 0c9h     | mono/right
+| YM2151    |  1st    | 0cah     | 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.
+
+VGMPLAY is still under development. The source code is provided in the

+# 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
+
+    A> wdate hr min sec
+
+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.
+

+
+Return the count of Characters Pending (A) in the input buffer of the 
+DSKY.  If the unit has no input buffer or the 
+buffer utilization is not available, the function may return simply 0 or
+1 where 0 means there is no character available and 1 means there is at
+least one character available.
+
+The value returned in register A is used as both a Status (A) code and 
+the return value. Negative values (bit 7 set) indicate a standard HBIOS 
+result (error) code.  Otherwise, the return value represents the number 
+of characters in the buffer.
