Introduction: Demonstration of an Old School TTL Logic Coin Counter in Action

This video is a demonstration of a coin counter I built from TTL logic. You would probably never do this nowadays. I started designing this around 1991 and finally finished getting it working around ~ 2000+ due to lack of a work space, business travel etc. Enjoy the video. If you really, really want the pain of building this you can find the instructable here:
