ABSTRACT:
An automatic scoring system for the game of bowling utilizing 30 scratch memories arranged in 10 successive groups of three, corresponding to the three possible score additions in each of ten successive bowling frames. Input information in the form of successive ball pin scores is sequenced on a common input line to each of the scratch memories. Thirty logic gating circuits, associated with respective individual scratch memories, and operating in time synchronism with the sequenced input information, determine, from the number of ball scores presented and the values of sequential scores, into which one or ones of the scratch memories successive ball scores are entered as a score addition in that place at that time. The system collates consecutive ball scores into the scratch memories such that summation of entries into from one to three of the three scratch memories for a logically determined complete frame represents the score in that frame.
