Not Unix but timesharing, and more demanding at that -- the University
of Illinois PLATO system had 1000 terminals and most days hit its
configured limit of 600 active users, in the 1970s, on a 10 MHz
processor.
Its modern day successor serves a lot more terminals than that; some
vague memory says a million connect hours per month...
