Method and means of sequentially observing player positions in predetermined game plays

A device for sequentially observing player positions in predetermined game plays comprising:

• a player position matrix comprising a plurality of indicia means designating a plurality of player positions for each of two teams and a plurality of ball positions;
• a memory means operatively connected to said matrix and comprising a micro-processor, a timer, a fixed memory and a replaceable memory, said fixed memory including a plurality of play sequences of predetermined time some combinations of which result in a score being achieved, an offensive play sequence group which contains at least one distinct offensive play sequence for each of a plurality of offensive team players and further including separate play sequence groups for each of said teams and various ball positions for each play sequence, and wherein said replaceable memory is adapted to temporarily store play sequences, the total playing time and the cumulative score for each team;
• a control means comprising a keyboard including a plurality of keys corresponding to said play sequences and a keyboard decoder, said keyboard and keyboard decoder being operatively associated with said fixed memory means to permit selection of one of said play sequences from each of said play sequence groups and both operatively associated with said replaceable memory to temporarily and simultaneously store said selective play sequences, and wherein said control means is adapted to permit the selection of any of said offensive play sequences;
• and whereby the changing positions of the players of each team and the ball will be visually, simultaneously and sequentially imposed on said matrix through said memory means, and
• an elongated support means, means for supporting said player matrix on said support means and means for moving said matrix longitudinally on said support means and means for moving said player matrix transversely of said support means.
