Title: Rare, er, controller thing, cheap
Post by: ander on Tue, 06 March 2018, 21:41:04
It has + and = keys and a digital display. But it's not a calculator, is it? (It's not an IBM product, either; don't know where the seller got that idea.) Some kind of video control panel?

I doubt it's usable for anything. But since it's cheap, seems high-quality, and has nice vintage keys (and is thus a potential fetish object), I thought you'd like to know.

The best kind of fetish. Also please be kind and rewind.

TL/DR it's a controller for a machine to read check MICR lines at high speed.

It would be sweet if there were beamspring switches inside there.

I am such a sucker for spherical keycaps with weird ass legends on them. Must resist.

Of course, I knew that... I was just trying to be modest.
