Interesting that there is no date on that document. The term "RSTS-11" makes
it clear we're talking about RSTS V4 or earlier. For that matter, so does the
hardware configuration: a boatload of DL11s for the user terminals rather than
a DH11 or DZ11 mux, because V4 only supported single line interfaces.
It's not clear if this is V4 or an older version. 24kW memory is a minimal V4
configuration, pretty marginal actually but possibly ok for 8 users max. (In
college I used V4A on a 28kW machine, 16 terminal lines, 16 users max though it
tended to crash at around 12.) The feature list doesn't mention some V4
(optional) features like "record I/O" so it's possible this was actually V3.
I also found the term "PDP-11/21" interesting. Has that been used anywhere
else? It's pretty clearly an 11/20 configuration.
