Abstract
A portable, battery operated storage device for analyzing performances in athletic events, such as tennis, includes an electronic random access memory controlled by a keyboard, and a digital display. The memory contains individual storage locations corresponding to points earned and points lost for each play. In addition, up/down counters in the device accumulate total points gained and lost for all plays. The player or spectator keyboard enters data identifying each play and indicating whether a point was gained or lost. Points lost and points gained data for each play are stored in corresponding storage locations in the memory. Total points gained and lost are stored in the counters. After the game, the numbers of points gained and lost for each play are determined by accessing the memory and displaying the contents of each of the storage locations on the digital visual readout. Total points gained and lost are determined by displaying the contents of the counters.
