Hi all, I bet somebody has some documents from this toy. I am starting to think about christmas, and all sorts of mechanical computers and toys. One of the other fun computer tricks I recall, is using 3x5 cards. You can punch a row of holes in the top edge, and selectivley cut slots thru to the top. So, a deck of cards with numbers on them, and appropriately cut slots, you can sort the deck with a pen, a binary sort by lifting the cards (its a bubble sort) What other kid ideas do you guys have? I'm going to bring a stepper controlled etch a sketch.
