Peter's statements are incorrect. Our MC500 has only one CPU, a 68010,
and does real-time processes with very little extra programmer effort.
Indeed, Masscomp's solution was to incorporate real-time facilities
into their version of Unix. That means special memory management, high-speed
interrupt service, RAM locking, etc.
