There were no home computers in ussr till late 90ies. Then clones of zx spectrum started to appear but nobody wanted them as they were useless to an average citizen. They booted straight into Basic language interpreter. Useful only for kids that learn programming. Just to highlight the gap at those times some organizations already had imported ibm X286 pcs when an average citizen had only a dick in his hand.
Yes I know some retards will now bring up wiki pages saying that comrade Sralin wrote unix himself and engineered at least 66 pcs with 6 cores and similar bullshit. I don't care. I'm talking about everyday life of a usual ussr citizen. There were no home computers. I can tell you even more. In the late 80ies not everyone even had a color tv yet and those who had had to repair it a lot and suffer shitty image quality.
For most of the people the first computerish thing they got as ussr collapsed was the chinese clone of NES called Dandy and then even cheaper noname clones of Dandy. Only after that real pcs from the west started to appear at homes.
