Univac Somethingorother


I have the option to buy an old bit of Univac machinery. The main problem is, I have no idea what it is. Parts of the enclosure are missing, and I've only seen it lying on its side on a pallet in a warehouse. Can you help ID it?

It looks to be about the size of a washing machine, but maybe a little taller.


Top

The top surface was mounted on hinges, so it could lift up like the hood of a car. It had a metal rod bent into a "V" that could swing up to hold the top up, very much the way a metal rod holds up the hood of my car while I'm cursing at the engine.


Labels

It had several boilerplate type labels, but I think they were each for the internal component that they were stuck to, not for the machine as a whole. I wrote down the info from a few of them.

This one might be for the whole machine. Unfortunately the "Type No" was very hard to read. It almost looked as if part of it had been intentionally rubbed away.
UNIVAC
Serial No 1973
Type No 700 0? 10
Volts 208/240
Phase Single
Amps 32
Freq 60
NFPA Type II
32 amps at 220 volts! Ay caramba! At least it doesn't want 3-phase power.

These two were stuck right next to each other, and there was a spot of dried glue that looked like it used to hold a third one.
Type 7151-00
Part 4102760-00
Serial F3734

Type F0890-03
Part 4102758-00
Serial F3734


Front(?)

On the side under those hinges were three electromechanical counters, tallying hours for "PRINTER", "READER", and "PUNCH". These are the sort that so many web-page hit-counters mimic, with a bunch of little cylinders with digits on them, so that the digit showing depends on the the position to which the cylinder is rolled.

Below that were a large number of circuit boards in a card cage. Two numbers from those circuit boards are 4101494-0108 (there were about ten of these!) and 4033728-02 (three of them). The few boards that I pulled out to look at all had discrete transistors, with quite a few resistors too. One board had a tiny control panel with switches labelled as follows:
Switch Settings
Up Down
MEM EN JAM NORM
BIT INT NORM
STACK INT NORM
SIDE INT NORM
ADRS JAM NORM
TIMING WIDE NORM
WR EN JAM NORM


Left(?) Side

On the side to the left of the one showing circuit boards were controls to (several?!) power supplies. The upper panel had some switches grouped in pairs,
MOTOR BLOWER PRINTER
PUNCH READER PROC/PRINT MEMORY H.V. PWR MOTORS
on/off on/off on/off on/off on/off on/off

It also had other switches with more generic-sounding labels that I didn't write down.

The lower control panel had six switches:
+6V +48V +3V -3V +12V -12V
CB1 CB2 CB3 CB4 CB5 CB6


Bottom

At the bottom were two seperate blowers, one in front and one in back, each mounted to pull air in through its own angled air filter.


If you can tell me what this thing is, or are interested in laying claim to it, kindly write to me at yakowenk@cs.unc.edu

          Thanks!
