How to build a simple computer from a cardboard box (or 2) and some marbles? Answered
Quite a few years ago (around 36-40) I read about a simple computer, made of a cardboard box, some dividers, and using 2 groups of colored marbles; whereas the object was to tilt the box and one marble would fall through. Depending on which of the 2 colors came through (pretty random) a move was made in the game (a simplified version of tic-tac-to).
Wrong moves were removed and eventually the "computer" learned to win the game every time.
BUT I can find no reference to this, nor the book it was in. I don't remember the title nor author, but it was very much like the book: "1, 2, 3...Indiniry" by Gamow (it is not this book, I have it and have read it through several times looking for it).
I have been looking for this info for about 20+ years, and decided one of the more sciencey readers amongst you all might remember it, the book or something to give me a clue to where to find this.
