Unix variant opens a path to managing multiprocessor systems

The Megaframe is a multiprocessor system composed of separate sets of MC68010 and IAPX-186 processors. One set handles all application-related tasks including process and memory management. Another set takes care of all file management, and the third set handles communications with peripheral devices. The high degree of independence enjoyed by each application processor means that adding extra processors gives an almost linear increase in the processing power of the system. The Unix kernel in each application processor provides user programs with an interface compatible with the Unix system v.
