Sounds kinda like a motherboard for a Heath/Zenith...
Z100? Was that the
designation? Those two processors were on the Z100 mobo... if you need to
see a picture, I can dig the mobo of one out of the crypt^Wbasement tonite...
Z-110/H-110 without built-in monitor; Z-120/H-120 with. 4 S-100
slots. Completely incompatible with IBM 5150, but fairly popular
when it first came out. The "H" models are the Heathkit "make your
own cold solder joints" form, but otherwise the same as the Zenith
units.
Unlike the Rainbow, the use of the 8085 was probably not such a great
idea after Heath/Zenith had been producing Z-80 systems.
