摘要
A sparemaker display for operation in conjunction with automatic pinspotters is provided in which control signals characteristic of particular standing pin combinations are stored in a read only memory and addressed to control a ball path display upon the occurrence of a corresponding standing pin combination on the machine table of the pinspotter. This control signal is outputted from the read only memory through a decoder/demultiplexer to drive a corresponding group of indicator lamps in defined ball path display configurations.
