Any idea what this is?

It looks like mini-computer memory modules to me. Available at a local auction. If I bid on it, I'll likely get it for less than $3. I have no idea if it would be useful as is or for parts.

Well, the thing was bid on by several people and the price was higher than my curiosity. It will remain a mystery.

There are some really ancient NC (or CNC if they actually had a microprocessor) machinetools from the early-mid '70's that were built on cards like that. Way before my time so I've only seen pictures on other forums, but each card would serve a specific purpose, like a linear interpolator or a resolver counter or whatever, and the machine would have a whole cabinet full of them on a wirewrapped backplane.

Apparently there are some of these dinosaurs out there still running too, which if those sold for real money, might explain why.

So that's my guess.
