Hi and thank You for sharing in advance. I am generally looking for info about Polish computers, and after seeing(legally) released for public papers about EC systems, I think that American or even NRD(GDR)/Stasi Archives can contain some info about vintage Polish computers. Especially would be great finding for example scheme of Elwro 700 Solum, or Elwro 600. Maybe is wrong thinking but Elwro was one of the biggest companies in Poland, sometimes called "Polish IBM", and in country where the whole month salary at late communism times was worth for example 10$ probably were people who were sending info across the iron curtain. Also these computers have less computing power than modern smartwatch, so maybe somebody released it to public, for historic interest.
