til: engineers in the USA knew that soviet engineers were reverse-engineering their CPUs, so they etched a russian message into one of the lower layers of the MicroVAX 78032 (you can't see it on the die, you'll only find it if you dissassemble layer after layer - like you'd do for reverse-engineering) that basically said "stop stealing our stuff". and sure enough, the message was found some months/years later (it takes time to smuggle that stuff) in a lab in Erfurt and led to awkward moments. 😁

they eventually succeded in (re)creating the first 32-bit cpu in the eastern block, the U80701, and in building a whole factory (by smuggling in machinery from all over the world). the first working samples were produced in october 1989...the gdr collapsed in november 1989 and nobody was interested in 5+ years old hardware anymore, so they never started serial production.
@aurora Oh huh, that's my town! I don't think any newspapers reported on it though :s
