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 5V Arduino. When you have completed building this kit you have your very own piece of computing history in your hands.
I designed this kit because I am interested in retro computing and saw the memory shield project built by Ben North and Oliver Nash. However, sourcing all the components was quite painful; I had to order the cores from Bulgaria, check their characteristics and tune the construction based on my findings. I also wanted to fit all the components onto one PCB with through-hole construction. The project turned out so nice that I wanted to make it into a kit to make this interesting piece of vintage technology accessible for everyone. The kit uses almost exclusively through hole components and anyone is able to put it together.
