Xts CP/M

( just an unoffical fork of the excelent RunCPM that was did by MockbaTheBorg )

You should rather take a look @ official implementation.

Xtase - fgalliat version @ Apr2109

Initial Aim : run interpreters on Teensy 3.6 (& even a small OS)

WANTED :

Additionals Hooks to execute some Hardware Native functions

in order to add CP/M - impossible behaviors :

• send files to/from SDCard (emulated DRIVEs or other ex. /Z/0/WALLPAPER.BMP ) (take a look @ XMODEM.COM anyway but uses LST: ? unsuable for now) -> now copy via Serial -or- WiFi

• activate / disactivate WiFi in STA & AP modes

• start / stop a telnet server

• some of these behaviors could be emulated by spe-memseg-addr to be used in other CP/M programs

  • or BASIC or Pascal own-written softwares (ex. play buzzer tunes, WiFi control, acceed to DFPlayer...)
  • working way : BdosCall + VT-EXT

• see ./ArduinoInterface/ samples (.BAS, .PAS, .ASM) that can deal w/ digital/analog arduino pins and some other BDOS improvements ...

• from Pascal BdosCall :

  • Hooked interrupt [225..229], that can receive an address of a String of 255 chars. wide ! (done)

Current/Initial compilation : On a Teensy 3.6 Sketch uses 73184 bytes (6%) on 1048576 bytes (+1MB). Global vars uses 72436 bytes (27%) of RAM, still 189708 free for local vars. max is 262144 bytes (~262KB).

• enough RAM & Flash remaining to add some hardware supports

• debug @ 9600bps / default => setted to 115200bps for YATL now

• with VT100 console & BUZZER support & BMP, PAK image format, MP3, WiFI, Keyboard support Sketch uses 138932 bytes (13%) on 1048576. Global vars uses 7124344 octets (47%) of RAM,

Layer impl.

• video
  • builtin TFT ILI9341 320x240x64K
    • inMem console (6x8 -> 53x30chars) // (3+1x5+1 -> 80x40chars)
    • the TinyFont mode is enough (80x25chars required)
    • VT100 emulation ( for colors + clrscr cmd + locate cmd ) to finish
    • EXT : can have gfx (even if OS itself is text based only)
      • currently have .BMP wallpaper support working
      • currently have .BMP sprites support working
      • currently have .PAK image support working
    • EXT : could have native-animated-gfx routines (Starfield, Raycast frame, 3D-Balls, ....)
  • EXT : HobbyTronics Serial-To-VGA (text-only) board
  • EXT : Teensy ++2 (5v) as TVOut device (gfx + text w/ enough RAM to handle descent resolutions)
• keyboard(s)
  • Vetch Mobigo console builtin keyboard see docs here
  • XBOX 360 Chatpad Serial builtin keyboard
  • HobbyTronics USB Host board for Keyboard (fr layout)
  • ZX Spectrum+ builtin keyboard (by Arduino MICRO)
• audio
  • PCSpeaker-like to play tunes (ex. play "MONKEY.T5K", play "aa#cd" ) done
  • MP3 tracks playback via DFPlayer (w/ pause, volume settings, ...) done
• WiFi
  • start / stop AP/STA (done)
  • manage a telnet server (done)
  • manage a simple webIDE (may use builtin SDCARD to store resources...)
  • wget some URLs (~done)
• fond a way to call ext. hardware
  • currently working : BdosCall (usable in Pascal, Basic, ...)
    • 225 to 229 are free (able to send a Pascal String[255] to a Bdos interrupt)
  • specific virtual FDD for assets, Z: (as original CP/M ends to P:), to store .BMP, .T5K, ...
  • CP/M itself could have additionals intrinsic commands
  • may could by poke() on specific mem address
  • Current CCP uses 60KB of RAM -> 4KB remains to make the stuff !?
    • 'cause if uses 60KB that means that mem pointers are 16bit long
    • so could address 64KB of mem ( /!\ BEWARE of BIOS & BDOS location /!\ )
  • look @ 2x PseudoFiles that can deals w/ Printers&Devices (PUN: & LST:) ....

Software

• Pascal IDE (text)
  • tpas30.zip
  • http://www.z80.eu/pas-compiler.html
  • online compiller : https://rextester.com/l/pascal_online_compiler
  • another one : https://www.jdoodle.com/execute-pascal-online
• mBASIC
  • 40KB RAM available when launched
  • https://archive.org/stream/BASIC-80_MBASIC_Reference_Manual/BASIC-80_MBASIC_Reference_Manual_djvu.txt
• Google Search
  • https://www.google.com/search?q=program+for+cp%2Fm&oq=program+for+cp%2Fm

Runs on

• Teensy 3.6 (Yatl)
• Teensy 4.0 (Yat4l)
• ESP32 (Yael + Yaeh)
• RPI0w (zxs)
• 'nux (ARM64 - Android's chrooted kali - native cpp) / (PC x64 ubuntu Linux)
• Android (Dalvik nor NDK : Not yet Ported)

How to run

• Teensy 3.6
  • copy CCP/* @ sdcard:/
  • unzip DISK/A.zip to sdcard:/A/
  • then boot (each DISK letter is a folder of ONE letter)
  • 
• 'Nux Box
  • make posix build (or posix_fb / posix_sdl for GFX versions)
    • needs libreadline-dev + ncurses-dev
  • make a ./distro/ directory
  • copy CCP/* to ./distro/
  • unzip DISK/A.zip to ./distro/A/0/
  • copy YatlCPM executable ELF to ./distro/
  • then boot : cd ./distro && ./YatlCPM (each DISK letter is a folder of ONE letter)

Usefull commands :

• EXIT
• XMODEM
• TYPE READ.ME
• SUBMIT TOTO.SUB (to run a ~batch script)
• FORMAT D: (will create & format a virtual disk w/ user 0)
• DIR *.BAS
• REN
• ERA *.TMP (delete one or more files)
• SCHED (to run a program later...)
• LOAD (run a .HEX file or compile it as a .COM file)
• Z80ASM TITI.ASM (to compile a .ASM to a .COM, see INFO.ASM & other samples on DISK A:)
• TE TOTO.TXT (text editor)
• PIP save.txt=orig.txt (to copy a file)
