Logic learning apparatus

Claim 1

A logic teaching game comprising: a housing having a plurality of two position switches mounted thereon and operable to generate combinations of logic ones and logic zeros, a plurality of discrete electronic logic circuits connected in parallel to one another, each of said switches connected to the input of at least one of said plurality of discrete electronic logic circuits to supply said combinations of logic ones and logic zeros, each of said logic circuits being unique relative to the other logic circuits and generating a predetermined output signal only upon proper operation of said switches connected to the input thereof, a plurality of light generating devices each connected to receive said predetermined output signal from one of said logic circuits in order to be illuminated to indicate a successful operation of said switches associated with said logic circuits, a plurality of cards each bearing a visual diagram representation of a different one of said logic circuits and each having a single output line, wherein said output line points to a single position adjacent a selected one of said light generating devices when said card is positioned on said housing, and means in said housing for receiving, aligning and storing said plurality of cards during both operation and non-use of the logic teaching game, such that input terminal representations on said cards are positioned adjacent said switches and said output line on said cards is located adjacent a selected one of said light generating devices.
