I was looking thru one of the yearbooks from my time at
University of Missouri, Rolla. I found what I think is a
photo of a GE-200. I "liberated" this system or one of
them to a lab I had, when they were mothballed, and I
could swear that is what the systems were.
If anyone recognizes them, let me know. This is the first
hint of any sort as to what I had. And my memory could be
wrong. The square indicator and switch style is very much
like what I recall for this particular system.
I had gotten handed a couple of very heavy trays of Lambda
power supplies which clearly were for some purpose due to
how they were mounted. I later found the system I think
was a GE-200 neglected in a stockroom in the EE building
and recognized that the interconnnect would fit the power
supply trays I had.
The system was transistorized, not IC I might add. That
was why it took 4 or 5 large Lambda supplies. Luckily we
had not broken the supply tray up and i was able to play
with it.
The other thing i think might be of interest are several
photos of an analog computer that the EE dept had. I know
there was another much larger system in the Physics
department as well, and maybe I'll luck out and find a
photo of it later.
Oh, and the blond at the keypunch. I might add that she
is probably retired now.
thanks

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.
