My dad had a 256bit memory module on his desk. Made out of sandwich of two pieces of glass and 16 vertical and 12 horizontal wires. Each intersection had a small ferrous ring.
Around that time he was programming and early computer and you could actually hear the memory bits changing. He was excited listening to it, figuring each click was a loop. Then her heard a different sound and realized he as hearing instructions and not loops.
