I'd wager a guess that most of the countries in the Eastern Block did have their own computers. In Poland, for example, there were the 8-bit Meritums [1], the Elwro 800 Juniors [2], the Bosman 8s [3], the Mazovia PC clones [4] complete with their own Polish characters encoding that has the peculiarity of containing one character that had never existed in Unicode [5], to name but a few, not to mention the Odra mainframes [6].

Communists had 1 positive obsession: exact sciences. See all that focus on math, physics, etc. They probably thought they could solve all the world's problems as equations, with the head of state as the "master variable manipulator".

  This was a necessary instrument for the arms race.

    Of course. Someone in the Politburo read 1984.

> I'd wager a guess that most of the countries in the Eastern Block did have their own computers. There's this beauty from Sweden: https://en.wikipedia.org/wiki/ABC80 https://en.wikipedia.org/wiki/ABC80 I'm guessing a lot of countries overall had their own computers, not just eastern block. We don't usually hear much about them because we base our computer history mostly on the canon of the US. I was surprised to read in "The Architecture of Open Source Applications" that my former university's computer science department made a very prominent sendmail version back in the day (IDA sendmail) and that this was noteworthy in that context. This field has been international for a very long time.

  You are aware that Sweden was not a member of the "Eastern Block"?
  - 59nadir 11y ago
    That was exactly my point. Most likely every country (overall) had their own computer. It wasn't an "Eastern block thing". The degree of separation was obviously higher, but not all "western" manufacturers were American. (Also: danskjävel...)

      I get it now. The context was ambiguous, though, so I don't quite get the downvote. Yes, we danskjävels made som as well. https://en.wikipedia.org/wiki/Regnecentralen https://en.wikipedia.org/wiki/Regnecentralen

Few people decapped MCY7880, and you mostly find russian dies inside.
