At some point in the mid to late 1980s, there was a craze in Minsk of seemingly everyone home-building ZX Spectrum clones. Probably the Ленинград design, though I'm not entirely sure. As I recall, all the components were off-the-shelf Soviet parts (K155 TTL series), so no ULA or anything fancy like that.

- varjag 5y agoYes it was, however when the factories started picking up they usually didn't use Leningrad version. Mine was a from scratch design (it came with schematics), and sure all of them emulated ULA with discrete logic - but usually not as half assed as Leningrad did. This was the huge advantage of Spectrum: the whole thing could be built from COTS components and the only imported part in USSR had to be the Z80A. None of those Sid, Frodo, Bilbo etc ASICs.
