Since it was in and out of the shop so quickly we
didn't get much of a chance
to check out the system (Z200? S200?) but it looked as if the mainboard was
pretty much just a backplane, with the 10MHz AMD 286 CPU on an ISA card.
Sounds like a Z-248, though I guess they could've had others
of that basic type that carried other model numbers which I don't
know about. Lage desktop case with 4 HH drive bays on the right
side. If I remember correctly, both the memory and CPU board were in
proprietary slots.
Anyone familiar with this beast? It looked pretty
cool. Could cards with
faster CPUs be installed in place of the 286 card?
There was a 386SX-16 board made for the machine that replaced
both the CPU board and proprietary Zenith memory card. The SX board
used 30pin SIMMs for the onboard RAM. I no longer remember who
manufactured the board though, but I have installed a few of them in
years past. The Z-248 was used widely by the US Navy and is often
found at surplus sales. As far as compatibility, it did pretty good.
Hope this helps.
