I recently came across a book published in 1968 entitled “How to Build a Working Digital Computer” by Edward Alcosser, James P. Phillips, and Allen M. Wolk. Believers in the “learn by doing” philosophy, they show how to construct such a computer using “simple inexpensive components usually found around the house or in a neighborhood electrical parts store”. This is often called the “paperclip computer” book since they use paperclips to create switches throughout the design.
