Any idea what this is?

It always wonders me how they managed to make work these things, with so many hand-soldered cables...
Can you identify some of the part numbers on the chips? That might help determine the exact function.
Hmm, definitely not repetitive enough to be a RAM array.
I'm gonna go with a paleolithic ancestor to modern FPGAs, where the "field programable" part means soldering all those jumper wires between different logic gates.

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.
