This paper describes the development of a microprogrammed, dual processor minicomputer system. The architecture of the special processor developed for the system is also described. The use of multiprogramming techniques with the microcode stored in a read/write memory together with a high speed context switching arrangement, gives rise to a powerful processor. A modular operating system based on a message/event system for a dual processor system is described. (Received October 1976)
