Nova Simulator Configuration

Introduced in 1969, the Nova was Data General's first architecture and one of the first 16-bit minicomputers. Its elegant and simple instruction set architecture prefigured today's RISC processors. The Nova family remained in production until the mid 1980's.  There were eight processor designs:
