There was a CP/M+ for it (the M4 could officially take 128K of RAM, I

Mind you, I am not sure why you'd _want_ to run CP/M on it. The 'native'
TRS-DOS 6.x (aka LS-ODS) is a much nicer OS, with loadable device
drivers, some (limited) I/O redirection, a better scripting facility, etc.
If you don't want 'the first', try to
get a Model 4, original
(non-gate-array) CPU board versions. It's got a couple of features not
found on the earlier machines, including an 80*24 text mode display and
selectable memory mapping allowing RAM at location 0 so you can run
normal CP/M as well as TRS-DOS, LDOS, etc.
Ooh... didn't know that the M4 could run CP/M. When I was in High School, our "Computer Math" class was done
with a M3 and M4 running
TRS-DOS. If I'd known I could have gotten CP/M for it at the time (c.
The Model 4 will run all Model 3 software, including booting all Model 3
OSes. If you were running Model 3 TRS-DOS (TRS-DOS 1.x) I can understand
why you'd want to run something else :-)
