Really fascinating construction in this early PC clone (Zenith ZF-151-52).
The whole computer is on 8-bit ISA cards, with just a small ISA backplane in the chassis (where normally a motherboard would be).

@PeterKratz yeah I’m not turning this one on, I’m probably selling it soon as I need to downsize my collection
@thomasfuchs beware, this thing has RIFA caps in the power supply.
@lopta yeah you can see the leftmost two cards are taller than the rest
@thomasfuchs I worked on Z158 and Z159 machines which were the same way. CPU/RAM card was a bit taller than a normal ISA expansion card as I recall. Turbo switch on the back. Pretty sure their 286 machine was also built on a passive backplane.
@thomasfuchs I wrote that from memory before I clicked on the photo. Z286 was the AT version, apparently.
@lopta nice! Such neat machines.
@thomasfuchs I can actually smell the old steel parts on my hands coming through that picture.
@guidoism I mean it’s in pretty clean condition for being 40 years old. Some TLC would make it look almost new. :)
