My fuzy memory on the subject seems to remember that Timesharing was Multiprossing whereas Multitasking was required for realtime processing. The distinctions started getting rather vague when the PDP-11 and proper interrupts came along -- before that the major concerns were over how you handled polling devices. (I wonder if IBM's mainframes still poll devices...:) (Note: I think Dec had some CPU with interrupts before the 11, and that with the 11 they went to a consistent interrupt scheme.) -- Jim Williams.
