Well, there's the self service card reader out in the hall
of the computer science building (upper left corner).
Many of the other pictures look like a Pace TR-48 analog
computer (or similar model). I remember one of those in the
basement of the EE building. Yes, I saw these computers in
the basement of EE. The middle row, right frame shows two
of them sitting side by side, I remember them being like
that. I did poke around inside, seems they ran off
unusually high DC rails (maybe 12 or 24 V) and had HUGE
collector load resistors, like 2 W, and the boards were
burned below these resistors. 12-bit machine, I sort of
vaguely thought they were made by SEL or one of the
predecessors of SEL. But, that is now a 40+ year old memory.
