Without trying to be too exhaustive, the whole so-called 'R' series in the East Block are 360/370 clones (I was an operator on a R-35 which was supposedly the equivalent of an IBM 370/145 - is there such IBM model? - and on a R-40 which was some System 360 equivalent). In Hungary we had the TPAs which were PDP clones (I believe PDP-8). The Soviets had some decent PDP-11 clones (can't recall the name). But the best were the East Germans They were making the Zilog 80 chip (I don't know under which arrangement). So they had this Z-80 @ 2.5MHz - it was HOT! I mean, you had to divert some cool air onto it; it run very hot (at least in that machine I was working with). But they had a machine which had this Z-80 int it and emulated (I believe) the PDP-11 instruction set! I recall that the programmer ladies(!) were afraid to change anything in their COBOL programs 'cause a recompilation on a ~200 line source took ~30 minutes... (Do you know that I can pick up a 40MB hard disk at Budapest for less than here in Ottawa? Hungarians are hot for high tech and we started to make IBM PC clones around 1985...)
