But on this list you get but find out other machines than the standard 8080/Z80
6502/6800 crop of cpu chips. Since you can't find the chips any more from other
less common computer systems I don't expect the software is out there at all.

PS. (wish list)Can the Cubix 6809 system run the open source of OS/9? That would make
a nice homebrew with a small IDE drive.
