VAX Simulator Configuration

The VAX was the most popular 32-bit minicomputer. Introduced by DEC in 1977, it remained in active production until 1999. The VAX family included many processor designs:

While the relationship between processor designs and system models is obvious for TTL and ECL processors, the VAX microprocessors were used in many different types and models of systems. For example, CVAX was the basis for the MicroVAX 3500, the VAX and VAXstation 3100, and the VAX 6200. A complete chart of the VAX processors and their instruction sets and system implementations can be found here.
