I don't think the 11/750 could have handled that many users on DZ-11s.
With DZ-11s no. But it is impressive what could be done with the
"good" hardware. In the mid 80s I was an occasional user on a 11/750
that at its peak had 80 (eighty!) terminals connected across a
university campus. Mostly terminals that could be switched between
different host lines (sometimes with a mechanical switch box) so the
750 was never 100% utilized, but even with ~40 people logged in,
responsiveness was bearable.
The interfaces as I recall were DHU-11s and DMZ-32s. The DMZ-32s were
weird beasts; the Unibus module connected to a distribution panel via
a 4-wire T1 line and could be kilometers away. The distribution panel
(which needed its own power supply) had 24 lines. I suspect the thing
was aggressively optimized for low CPU overhead.
