Hello. So I've been trying to make CCP/M-86 3.1 run on QEMU.
I've been using the source files to build it.
 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.

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.
