Dumpster Find... USSR Computer Tech!
Look, Mum! Soviet Computer!
A look at tens of Soviet computer boards from the '60s/'70s found in a e-waste dumpster. All germanium diode & transistor logic, nicely hand-routed single layer boards, way looser than those in the Soemtron, easy to follow... with some interesting twists too.
The modules might come from early generation of the ES EVM "Ryad" a.k.a. "Unified Series" mainframe computers, based on reverse-engineered IBM System/360. It's worth noting that apart from components from all over the Eastern Bloc (e.g. GDR transistors and capacitors, Polish capacitors), Western capacitors and semiconductors are there too.
