4x4 core memory with Fair-Rite 5952020201
I got vintage cores designed for core memory on eBay.
Left: what I have used for core memory.
Center: what I got. It's so small!!
Right: 0603(1608) SMD resistor.

4x4 core memory board with LCD display. The cores are available today in digikey, Laird 25T0135-60P, and are not deadstock ones.
I made the number of turns for a core two for column and row lines because coercive force Hc of the core material is high.
