    Here is the link to the project: https://gitlab.com/ccpm-86/ccpm

    It's primarily based on info by Matthias Thumann I found at http://mthu.freeshell.org/tmp/cpm/cpm.htm

    So, for me it builds and runs.
    For real hardware there might be problems with floppies (haven't tested
    it yet).

    I'm also trying to improve some things such as the BDOS c_readstr (allow
    line editing) and t_set (should also modify the internal QEMU date and
    time) functions.

    In order to run it on the floppy, I created my own cpmtools diskdef for
    the 1440K floppy. The hard drive is not supported yet, but I will try to adapt the format used by the Hampa Hug's PCE CCP/M-86 3.1 hard drives.

    Let me know if you tried to test it, and if you have some ideas on how
    to improve or modify it.

    Just curious, what line editing commands will you support on the read
    string function?

    It's an interesting project. I wonder if it could be adapted to port
    CCP/M-86 to the V20-MBC board? It only has one serial port but virtual
    consoles would be cool.

    That brings back memories. Once, long ago, I decided I wanted to add
    simple line editing to CP/M-68K. I started by creating a C source file
    that compiled into a binary identical to the existing consbdos.o. OK,
    not quite identical as there was one thing I couldn't figure out.

    Then I added the editing functions.

    It was interesting reading the DRI source code when that became available.

    Thank you! I think it should be possible to adapt the XIOS module for
    the board. But I'm not familiar with it.


    It uses a V20 CPU and runs CP/M-86 as well as CP/M 2 in 8080 emulation mode.
    It has 16 emulated disks on SD card. More details here

    Did you manage to recreate/compile/assemble also the submit command
    (external program) ?
