Further, If you can’t remember ring core magnetic memory then you ain’t old school. :0)

yah in the air force i worked on a system that used iron ferrite core memory...wires with a little pieced of ferrite to store the state. Hard to convey that to anyone today.

An earlier Freeper had it right. A read wire and a re-write wire and one to blank it. Once you read it, you had to rewrite to it to keep the state.
