Trial Core Plane ready

A project log for ED-64: A discrete 8-bit computer

ED-64 will be an 8-bit computer built with discrete components, and will feature a ferrite core memory (documented as a separate project).

I've populated one of the core planes to experiment with. I've discovered it's quite tough getting that 4th wire threaded, so I will try a 3-wire system i.e. the sense and inhibit circuitry with share the same wire.

The next step is to put together some current drivers and sensing circuitry.

3-wire systems tend to be later generation. I've got a pretty good idea how to go about it.

Most core memories I know of have only 3 wires...

Good luck with the electronics !
