Purdue EE had I think 2 Gould PowerNode 9080s. I don't know anything about
the internals, but Purdue EE was doing development or testing for them. It
might have been a port of 4.3 BSD. As an undergraduate you could get an
account on for the asking and it was significantly faster
than the overloaded Dual VAXen. It also crashed from time to time.
