Motorola had some investment in the region. 6800 class CPU fab. Maybe made under licence. I remember my dad touring Poland, Hungary discussing vlsi conference stuff with people there in the 80s.

The UK maths/compsci circuit had good links with Poland's because of Marian Rejewski and cryptography history. Well.. good and not good, he didn't always get recognition for what he'd done.

UK was involved in (in)famous story of production of K-202. The story that to these days is a highly controversial topic due to various groups blaming different people (from Jacek Karpiński to communist government) for it's failure tho it was pretty impressive and innovative architecture at the moment it was presented to the world, tho prolonged problems with production deleyed it's arrival so much it was no longer able to keep up with western rivals especially integrated CPUs as K-202 was a TTL based architecture.
