Do you know if they run on 6502s and other Western chips of the time? Were they cloned, or imported? Or were there Soviet ISA's?

I remember reading years ago about how Russian computer scientists in the cold war were more honed in algorithm design, because they basically had to squeeze as much as they could out of their processors to compete with faster Western hardware.

Morskoi Boi/Sea Hunter has no computer, or chips for that matter. It's 1960s tech.

Some computer based arcades started to appear in late 1980s, but more like Pong clones and similarly simple "racing" games with 2600-like sprites. At this point the "coops" started popping up, offering pay per minute experience on Atari 800 and ZX Spectrum.

There was no Soviet 6502 or Z80 clone; there were however 8080A clones and DEC LSI-11 inspired designs. There were a bunch of creative programmers sure, although there hardly was a real "school" and CS remained largely backwaters to the West.

> The U880 is an almost identical copy of Zilog's 8-bit Z80 microprocessor.

I wrote my first machine-level programs on that chip (I didn't have an assembler, only a dis-assembler, so I hand-translated the code and then used the dis-assembler to check if I had made typos).

There were Soviet and East German Z80s, Bulgarian 6502s, etc.

If you mean the T34 one, yeah it was in USSR in the sense there was tenderloin in the shops. I.e. we knew the name but I never met anyone who could get hold of it. Even then not sure it was even heard of until 1990s.

Bulgarian 6502s were probably shipped with their Apple II clones. Those were hard to come by.
