OH cool, he's already stolen the core memory.

Never heard of that brand or machine.

Not sure stolen is the right word. The company seems to be involved in instrumentation rather than computers. It's probably not a general purpose computer of any sort. They seem to be mainly involved in radiation detection. Makes sense for where it was found.

It is probably a pulse-height analyzer, try digging around for that term and Nuclear-Chicago

http://www.versci.com/

has a general description of the technique and why there is core memory in there.

Nuclear-Chicago, Nuclear Data, and Nicolet were all in that business

GD Searle is (was) a large medical instrumentation company in Chicago.

There was a better picture of the front panel around and it doesn't look like a computer.
