The next is a 'Rex Microcomputer System', model REX-1032, "Manufactured by
Realistic Controls Corporation of Davenport, Iowa". I'm guessing this is a
kit computer that's been put together by this local company, but "Rex
Micrcomputer" gets me nothing via google and breaking it down gives me
screeds of irrelevancies. The machine has a Z80 microprocessor, although
it might have another (ala Rainbow) and I just haven't dug far enough.
REX was late like 1979 to early 80s not later than 1985 time frame.
They were not seen around my travels and I wondered if they were really
vaporware. It's a Z80 CP/M crate. More like Robin not Rainbow.
The last is quite a beasty, weighing plenty thanks to
its significantly
hefty linear power supply. Intersil Development System, ISB 80DS 3020-120.
Got six apparently serial ports on the back with what I think is a console
cable hanging out one side. What I like best is the socket mounted in the
front plate for reading/writing 24 pin DIP chips. Two 8" drives with
diskettes in them, God only knows if they're still good after sitting out
for this long.
Likely a 6100 (PDP-8 in cmos) powered deveopment system though they
sold 1802, 80c85 and 80C88 too.
With some TLC they sould still run if rust or corrosion are not evident.
