Help identifying Mostek machine

  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.
