These sound like standard Mostek STD-BUS cards. The cards were available
separately so it may or may not be a Mostek computer. As luck would have it
(your's not mine!) I found some Mostek manuals for some of the cards today
along with some DRI CPM manuals. I haven't gone trough them yet but I'll
post a list after I do. BTW Steve Robertson is the expert on STD-BUS
stuff. He found one of the system developers that used to work for Pro-Log
and got a TRUCK load of that stuff.
BTW II United Technologies bought out Mostek so Ian's computer could be
considered a Mostek machine.

Mostek Matrix 800, but it has a 1.2meg 5 1/2 drive and an MFM hard
drive. My machine runs CP/M and has a Z-80. I have the system disks,
albeit on 5 1/4, and I can make copies for you if you need them, but
you'll have to find a way to either convert them to 8" or to hook a 5
1/4 drive to the computer, but even then I don't know if the disks
would be compatible.
