The most amazing timesharing system I've seen is PLATO. In 1977: 600 active users,
highly interactive, on a pair of Cyber 73 (CDC 6500) dual CPU machines. Each CPU good for
about 1-2 MIPS, so that's pretty good. Even with a customized workload, that was a
tough lift; typically about half the keystrokes would require "real work". Not
like a command line based system where most keystrokes just get echoed and stuffed into
the current line buffer.

In the mid-to-late 70?s, I was an undergrad at CMU. I had accounts on the
CS department?s systems. When I started, it was 2 KA10s. Eventually a
KL10 was added (all running a *heavily* patched version of TOPS10).
During the day it was nearly impossible to get stuff done with ~200 faculty
and grad students on-line (on each system).
