Soviet 68000 CPU bit slice implementation?
« on: June 25, 2024, 11:31:43 pm »
From what I find about Soviet CPUs and the Motorola 68000:
* The import of 32 bit CPUs (including the Motorola 68000) was restricted under COCOM.
* No Soviet clone of the 68000 is known, but a related part being the Motorola 68881 FPU has a Soviet clone.
* Apollo/Domain used a bit slice implementation (AMD 2900 family) of the Motorola 68000 in some of their workstations.
* A number of members of the AMD 2900 family has Soviet clones.

Does anyone know of a Soviet bit slice implementation of the 68000?
If it runs on Linux, there is some hackability in it.

Well, this doesn't answer your question, but modulates a bit the fact that they never used any 68k: there was the Besta workstation, with a 68020: https://en.wikipedia.org/wiki/Besta_(computer)

WAT? If you are talking about КА1801ВМ4/КН1801ВМ4, then it was an original domestic design. And Л1839ВМ2 reverse engineered VAX-11 FPU.

I used an Apollo DN660 for a short time. As far as I can remember it was a clone of the 68020, or possibly a 68010 not a 68000.
