Hmmm, thats getting pretty close but I guess I'm thinking of for if-then-else logic at least. Or a simple adder. Must be literature on making machines out of simple stuff (non-IC) for adding.

Well I guess we are using the term "computer" a little loosely. But if it could play tic-tac-toe then it made decisions based variable input, thats kind of like a computer. And using an RCX would definitely NOT count. Bob (...) (25 years ago, 30-Jan-01, to lugnet.robotics, lugnet.general)
