It was the 1960′s, and people were building some very interesting digital computers. One of them was the Digi-Comp II, which we have written about extensively: a binary mechanical computer based on rolling marbles and flip-flop gates.
For an entirely different approach, look no further than How to Build a Working Digital Computer (1967) by Edward Alcosser, James P. Phillips, and Allen M. Wolk. You can download it as a free e-book (PDF, EPUB, Kindle) at Archive.org, thanks to the BitSavers PDF Document archive.
