Magnetic-core memory was the go-to RAM platform for computer systems from the mid-’50s to the mid-’70s. Core uses tiny magnetic rings with interwoven wires (three per core) to read and write information, with each core storing 1-bit of data that can be switched from 0 to 1 based on the magnetic orientation. While core memory hasn’t been used in any significant or minor computer systems for over 40 years, some just love playing with retro tech, including Andy Geppert, who created an Interactive Core Memory Shield for Arduino.
