Magnetic Core Memory Circuit

A project log for Magnetic Core Memory The Dr Cockroach Way

My not so fancy example of Magnetic Core Memory using fairly cheap cores and free parts from my junk box.

This is about as basic/bare bones of a circuit that I think will work and still give solid Read results. The stringing of the core wires using number 38 enameled wire was not as much of an issue as I was fearing.

The Sense circuit starts off with the Transformer and feeds into a very basic Differential Op Amp. The detected read pulse then triggers a Nand gate and switch that then sets the S-R Latch. This circuit is adapted from the Casio AL-1000 calculator from 1967/1968.
