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.

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.
