GENIAC


An interesting kit builds circuits that solve problems and play games.
"Electric brains" that work in much the same manner as giant computers can now be built quickly and cheaply by the novice using the new Geniac Construction Kit.
One of the most remarkable kits ever introduced to the public, the Geniac kit provides material and instructions for building 125 separate circuits for operating as many "brain machines." Among the devices that may be built are logic machines for comparing and reasoning; cryptographic machines for coding and decoding; games such as tic-tac-toe and nim; arithmetic machines for both decimal and binary computations; puzzles such as "the space ship airlock," "the fox, hen, corn, and hired man;" and miscellaneous devices such as a burglar alarm, an automatic oil furnace circuit, etc.
