Funnily enough, the 1801 microprocessor [1] wasn't stolen from DEC. Or rather, the instruction set was the only thing stolen. The 1801 was a new Soviet design originally with its own instruction set. It was later adapted to the PDP-11, probably because of the popularity of the PDP-11 and its software in the USSR. DEC never manufactured anything like the 1801, targeted more as a microcontroller than as a microprocessor. (Soviet military and aviation industries were the original intended use.)
