OSM ZEμS ISA passive backplane PC

Circa 1984

The only way I know that this is a ZEμS is from reading the BIOS

I suppose I can try to get it working, I do have 8-bit memory and multi-I/O cards, but in the end I'll have an 8088 based PC clone that's not really PC compatible (note the 6881 DUART). Rest of the lineup is 8237 DMA Controller, 8259 Interrupt Controller and 8254 Programmable Timer.
