The PDP-11/40 in the University of Toronto's
Computer Research Facility
(CRF) had a GT-40, and the lead EE prof there loved the screen editor RT-11
provided for it. I never used it, but I was intrigued. (I did land the LM a
few times, though. More than a few.)
Across the raised floor aisle was the PDP-11/45, which ran Unix from 5PM
to 8AM if I remember right, RT-11 the rest of the time, until some date
around 1976 or 1977 (?), when Unix became an unstoppable force for
innovation.
Also the approximate date of the rt11 emulation being viable on Unix...

Oops; reverse gravity (for the Sun) was implemented
for Space Wars (or
whatever it was called; this was ~40 years ago, so don't expect my
memory
to be the best).
I wonder how many GT40 Spacewar implementations there were?
I have seen two: one from MIT, the other from Stanford.
