If you like this kind of stuff I highly recommend CuriousMarc on YouTube - excellent humor, guest appearances from Ken Shiriff (his silicon-die reverse engineering posts are frequently on the front page here) and other smart folks, a fleet of logic analyzers and high tech diagnostic equipment, etc. Much fun while repairing vintage computers. The restoration on the Apollo guidance computer is a classic.
