@sos yes, that works too
I should dig more into post-89 stuff too because I only know what developments have happened in Russia, I don't know what the rest of the Warsaw Pact did (I live in Romania and from my perspective and from what I've seen, development essentially stopped around 1991, we actually got a huuuuge head start in IT compared to the USSR, but this deserves a post of its own (which will definitely happen))
