About ten years ago, we designed and made an Arduino shield implementing “core memory,” a technology that was sixty years old even then. Our shield stored 32 individual 1s or 0s using magnetic fields going either clockwise or anticlockwise around 32 tiny doughnuts of magnetisable ‘ferrite’ material. This kind of memory, invented in the 1950s, […]
