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.
Claims10
A control and test circuit for electronic pinball type game devices having lights, ball switches, ball ejectors and score display means responsive to movement of a pinball over the game surface, said circuit comprising
- a. driver means for operating specified lamps and ball ejectors,
- b. a switch matrix means having a plurality of switches connected thereto, said switches being operated by ball contact with various locations on said game surface,
- c. computer means for monitoring said switch matrix means and controlling said driver means and said score display means responsive to detecting switch operation in accordance with a program therefor, and
- d. test sequencing means connected to said switch matrix means for causing said computer means to sequentially operate each light, ejector, and switch position to test said game, said sequencing means including means for repetitively testing a given light, ejector or switch position before proceeding to the next test position.
