Core Memory

Core Memory Shield for Arduino

This is a DIY kit for building a 32-bit ferrite core memory. Magnetic-core memories were the predominant form of computer memory from the mid-50s until the mid-70s. They work by storing information into the magnetic field of a ferrite core. It is non-volatile, meaning that it preserves its contents even when power is turned off. However, this type of memory is power-hungry, requires a lot of space and needs to be protected from strong magnetic fields. Also the process of reading the memory destroys its contents so that every read must be followed with a write. To make a long story short, this is a hilariously impractical memory extension shield for your 3.3V / 5V Arduino. When you have completed building this kit you have your very own piece of computing history in your hands.
