ABSTRACT:
An electronic device for calculating, storing and indicating the scores and related information for a game of tennis is described. The circuit provides for the special requirements of tennis and similar games by recognizing the existence of an endgame condition such as "deuce" in tennis and registering each new score as a function of the previous score and the point most recently won. Both up-down counters and decoders using non-volatile memory, including "read-only memory" (ROM) are disclosed for the point-calculation function, and a display encoder is described which efficiently provides for the display of alphanumeric scores, including "deuce" and "advantage" conditions. The invention includes features for indicating court change requirements, elapsed time, time of day, and display emphasis when a game is won. All score calculations are subject to a clear-entry feature to rectify operating error.
