The Soviet 1801VM2 LSI-11 processor

The Soviet-made 1801VM2 CPU (a binary-compatible implementation of the PDP11 instruction set and QBUS interface) was developed in 1982. The 1801VM2 is a further development of the earlier 1801VM1 doubling the original 5MHz clock speed. From a constructive standpoint this CPU is a completely independent development.

There's a wealth of interesting computer technology in the former USSR, and it's great to see more of it make its way online.
