        Sounds like an early Datamaster to me. I have a Datamaster (5123), but it has
a green-screen, not a B&W one. Otherwise the description matches.

        As I understand the Datamaster, it really was the predecessor to the PC. It
was desktop based, although you needed a large desk <g>. It had an ISA-like
bus into which you could plug-in cards. My guess, from talking to someone who
worked on the project, that it was a business machine (A/P, billing, word
processing, etc.) that fell out of favor when IBM introduced the PC in 1981.
The PC was 1/3 the size, probably 1/4 the weight, much faster, and used 5-1/4"

        There are several Datamaster owners here who can fill in more about the
actual specs. I don't use mine much because I have a blown ROM chip that
prevents me from booting...
