The first prototype used some very small cylindrical magnets, with wood pins glued at each end.

They were put inside a paper cylinder with a coil wrapped around.

Steel plates with a hole in the middle were glued at each end. Powering the coil moved the pin up or down, and the steel plate were keeping the pin in position, so it can be "read" without pushing the pin down.
