Retro USB drive uses magnetic-core memory for sneakernet file transfers

By PulseAugur Editorial · [1 sources] ·

A Japanese researcher has created a novel USB drive utilizing magnetic-core memory, a technology from the mid-20th century, to transfer files between computers. This retro-modern device, approximately a foot square, can store a mere 128 bytes and erases data upon reading. Despite its severe limitations, the drive successfully transferred a text file and a small bitmap image, with an LED array visualizing the data transfer process. AI
