I would imagine that home computers did not fit particularly well into the Marxist-Leninist ideology. Computers are means of work, therefore they belong in factories and research institutes. The State and the Party would not gain anything if members of the working class wasted their time and energy on hacking computers at home instead of striving to serve the glory of Communism. That would be perceived as decadent and frivolous, and therefore was probably frowned upon by the Party officials in a similar way to production of sport cars and other such stuff.

In Hungary and Poland, harsh as it was, the communist regime was peanuts compared to the Soviet Union. The Party had much more control over people's lives there and so I guess that's why of the reasons they got home computers so late.

I had the same idea about non-precision sockets, I will try them as soon as I unpack.

So, we have Soviet CPUs and peripherals, Soviet SRAMs and EPROMs, but how about glue logic? Did they also make 74xx parts?
