Abstract: A moving goalie circuit is disclosed herein. The moving goalie circuit includes a first operational amplifier, having a linear feedback. A second operational amplifier is connected to the first operational amplifier. The second operational amplifier is an integrator. A relay is connected to the output of the second operational amplifier. The relay is selectively connectable to a timer for controlling position of a cursor or goalie image on a video screen. The first and second operational amplifiers produce a triangular wave which causes the timer to sweep repetitively the goalie image back and forth across a playing screen.

Abstract: A handicapping circuit for handicapping electronic visual games is disclosed herein. The handicapping circuit includes a plurality of input NAND gates, connected to a pair of counters. Each counter of the pair is connected to a logic gate. Each of the logic gates is connected to other portions of the game circuit. A first counter of said pair is incremented upon a first player's leading score differential. A second counter of the pair is incremented upon a second player's leading score. The logic gates are activated when either of their respective counters reaches a count of four or eight. The count of four or eight at either counter indicates that one of the players is leading the other player by four points or eight points. The signal received from the NOR gate is channeled to other portions of the game circuit, which increase the size of a paddle image controlled by whichever player is trailing.

Abstract: An amusement device, the subject matter herein, includes a support, which is particularly adapted for mounting on a floor. A hollow housing is secured to the support. The housing has a continuous bottom and side walls, and is open at its upper end. A table top is hingedly secured to the housing and is releasably locked thereto. The top has a screen opening in its center. A cathode ray tube is secured to the top, with the screen of the tube adjacent to the screen opening substantially parallel to the upper surface of the top. Electronic circuitry is mounted on the interior surface of the top and electrically connected to the cathode ray tube. A logic board is mounted in the housing and is connected to the electronic circuitry to generate the image of a ball moving across the screen and images of a plurality of paddles to give the appearance of a paddle striking the ball and returning it. A plurality of control knobs is mounted on the top for controlling the paddle images.
