This is just remarkably uninteresting. Interesting fact however is that there is no CP/M simulator for Linux. Only MSDOS has. So you have to first run DOSBOX and then CP/M. -- I recently found copy of MUMATH from 1979 and it was as good as I remember it was.

There are plenty of CP/M simulators for Linux, but they're very niche and hard to find (and use).

I used to do C development for the Z80 using one; it translated CP/M syscalls to Linux ones, and would let me run the CP/M version of Hitech C more or less as if it were native. It worked all right. Hitech C was only a K&R C compiler and didn't produce great code, but it was entirely self-hosted.

The script and emulator I used came from here (look for 'Hitech C on Linux'):

...but while searching for that I found this other emulator, which looks a bit more maintained:

Do you mean the text? I was writing the text for me, as some kind of project log. Actually, I found a couple of errors in the design while writing which I wouldn't have found if I haven't written the text.

The text may only be interesting for people building or thinking about building a retro microcomputer.
