I think this machine was the diskless sibling (possibly the predecessor)
(and maybe even the predecedent) of the Intertec _Superbrain_ cp/m systems
we had at Scientific-Atlanta in about 1980-82. My memory is that the system
had a single motherboard, very few options, the usual dumb-terminal cursor
addressing and character attributes (but no graphics), and came in three
disk configurations: one 5.25" DD/DS, two 5.25" DD/DS, and one diskette plus
one internal hard disk. I could be wrong about the last. My two-drive
model routinely burned out the disk drives, since they had rubber-band
drive and ran _all_the_time_.
The Superbrain looked like a reasonably smooth Adds terminal. If your
Compustar looks like a terminal, it may _just_be_ a terminal. If it
looks like a chassis, it may be a multiuser cp/m of some kind. What
does it look like? Any connectors which might be fast enough data
paths for a shared-disk transfer?
I have some old disks from my Superbrain, but don't at the moment have
any way to read them. The sector size is too large for the BIOS of my
SD-Systems boat anchor, and I never got a 5.25" drive to work convincingly
with it, anyway.
Maybe this will jog someone's memory on the _Compustar_.
