Title: Electronic control and test circuit for pinball type games
Abstract:
An electronic test circuit is disclosed for pinball type games. A microprocessor is programmed to provide scoring responsive to detecting the actuation of the various switches located on the game surface. A sequencing device controls operation of the microprocessor to perform a test routine whereby the microprocessor will sequentially operate every light, ball ejector and switch position to permit testing of these devices for possible repair or replacement. The sequencing device can cause the microprocessor to continuously cycle through all of the test positions or can cause the microprocessor to single step through each test position and repeat testing of a given position as often as necessary to correct a located defect.
