Oh my, that is an oldie.

The core memory I've got is planar on a PCB.

The one I have/had is/was a PCB a bit more than a foot square with
thousands of tiny ferrite rings suspended by a matrix of wires and a
third wire that zig-zagged through every core.

It either got shoved behind the book shelf in the beddroom or slung out -
I can't remember which.
It should be 4 wires through each core. One each X and Y, and two the
zig zag through them all. One of the latter is sense, the other is write.

Its decades since I set eyes on it.


Can you imagine sitting and wiring those things all day long? I'd
rather glue the hair on tennis balls.
