The story of the CT-650, a computer built out of paperclips and other household items. It includes directions on how to construct old-school technologies like core and drum memories and front panel displays. The book, How to Build a Working Digital Computer, gave away all the secrets to nerdy schoolboys in the late 1960s. It’s inspiring to think about. Maybe a hobby project in the works?
The parts list for core memory (see below) include paperclips, scrap wood, a tin can and adhesive tape. Before there was Make, there was paperclip computer!
