A portable battery-powered golf analyzing device includes a keyboard usable in an input mode to insert data describing each golf shot made by a player. The data is formed into a digital word and stored in memory. The memory is of a type which is not erased unless a specific signal is intentionally applied thereto. In an output mode, the keyboard is used to form a digital word describing desired data. The memory is then searched and each stored word is compared with the inserted word. Correspondence between the inserted and stored words is counted and the results displayed. A receptacle for the portable unit includes a power supply for recharging batteries in the portable unit and circuits for applying an erasing potential to the memory. Indicators instruct the operator through the sequence of steps in entering a description.

An apparatus for storing and retaining data describing a plurality of events and for selectively displaying cumulative descriptive information about those events comprising the combination of a keyboard having a plurality of keys; first logic means coupled to said keyboard for forming a digital word having a predetermined bit length in response to operation of at least one key; an addressable memory; a clock for producing a sequence of timing pulses; a mode switch having an input position and an output position; input logic means coupled to said memory for permitting successive parallel storage of each word formed by said first logic means when said mode switch is in said input position; output logic means connected to said clock, said memory and said mode switch for responding to pulses from said clock only when said mode switch is in the output position to sequentially read out each word from said memory; comparator means coupled to said first logic means and to said memory for comparing each word read out of said memory with a word formed in said first logic means and for producing an output signal when correspondence between the compared words exists; and means for accumulating a count of said output signals and for displaying symbols representative of said count.
