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.

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.
