ABSTRACT:
The present invention provides a portable microcomputer-implemented bowling aid which indicates to the bowler (i) correct starting position and (ii) correct board marker over which to roll the ball after its released so as to maximize pin count with minimum data entry problems.
In accordance with one aspect of the present invention, the bowler first inputs game parameters such as right- or left-handness through I/O elements to a RAM of a microcomputer operationally connected to a bowling alley replica display. The replica display includes representations of (a) triangularly configured pins 1, 2, 3, . . . 10, (b) the bowling lane, (c) the foul line, (d) a series of board markers or spots adjacent to the foul line but on the pin side thereof and (e) a series of foot positions to the start of the bowler's approach to delivery of the bowling ball. The representations related to (a), (d) and (e) are keyed together by programing steps. As a result, control signals are generated by the microcomputer to control a logic driver circuit in series with LEDs of (d) and (e), supra. However, the drive current for the LEDs is not sourced from within the microcomputer. The algorithm for operations is in ROM stepped through operations by the CPU within the microcomputer.
