Looks like some kind of memory.

It is core store - old fashioned non-volatile memory.

Each little 'ring' of magnetic material at the intersection of the wires is a single bit of memory. The bit is stored as a magnetic field. Because of this, the power can be removed and (because of the remnant magnetic field within the material) the program and/or data is stored and is there when the power is restored again.

What a cute little core plane.

I had a small core stack virtually identical to this with similar number of cores that I saved from a junked 1970's japanese desktop calculator.

Planes that size seem to have been common in industrial controllers until bubble memory became the norm; at least from what Ive seen.

How much memory would that be?
