Is there anything particular you would like to know? I've heard a little about Setun from my parents, but nothing too exciting, I can ask around if you're interested.

For a little context: my mother studied cybernetics and father studied electrical engineering in USSR in 70s. They still have their college textbooks lying around, so I can try to dig something up for you from that era. But keep in mind, even in 70s it was obvious that USSR was decades behind USA. Heck, my first algorithm textbook was my parents' 2nd edition of Knuth's TAOCP (interestingly, my parents combined have 1 copy of 1st volume, 0 copies of 2nd volume, and 2 copies of 3rd volume).
