No, the ARPAnet one was a Unix system in the advanced computer center, the
building that was originally built to house Illiac-IV. The one I'm talking
about was standalone, a DOS system in the computer science building.
It was pretty weird in that it ran a PDP-11 simulator (on the PDP-11) so
students could write something approximating bare-metal software but get some
debugging help if things go wrong.
They moved that course to CDC, and I helped write the analogous thing for our
Cyber (a Cyber emulator on Cyber).
