RT-11 is a fine system. We had an 11/05 in the WPI computer science lab
that I was an operator in that could run Unix and RT-11 (I always picked
RT-11). Modeling was done on a connected Tektronix four thousand
something, but it wasn't zippy fast due to the 9600 baud maximum speed
of the serial interfaces.
The mechanical engineering lab had an 11/45 running exclusively RT-11
with a GT40, which was a completely reasonable machine. Updates were
just wonderful, but you'd get flicker if your display list got too
long. That usually meant you needed to get clever about coalescing
display commands to shorten the list.
This was never as straightforward as I thought it should be; eventually
in another class I discovered that the problem was NP-complete in
certain cases.
