Polymatt has created a USB drive using hand-threaded magnetic core memory, salvaging parts from an old Russian computer. This device represents a DIY response to the current semiconductor shortage, showcasing an ancient memory technology.
Polymatt's project stands out as part of a larger trend among PC enthusiasts seeking alternative solutions amid the ongoing memory shortage, termed the 'RAMpocalypse.' The DIY community is increasingly turning to outdated yet fascinating technology to meet their needs.
The USB device is constructed from 64 hand-threaded iron rings, each capable of storing one bit, totaling 64 bits of storage. The use of magnetic core memory, which was famously utilized in Apollo spacecraft, signals a creative and nostalgic approach to memory solutions.
The project incorporated components salvaged from an old Russian computer, highlighting a resourceful use of available materials. Although it features only a small storage capacity, the drive's aesthetic appeal is noted, as it is submerged in silicon oil and could accommodate an LED for each bit, though this feature was ultimately abandoned.
Polymatt tested the DIY memory device, which allows users to edit a single persistent file named core.txt. The project not only showcases the durability of this old technology but also reflects on the possibilities of modern applications for retro components.
