ABSTRACT:
An apparatus for tallying the finish results of a plurality of racing members includes for each one of the racing members a sensor having properties for providing an electrical signal in response to the arrival of the associated racing member at a finish line. A memory includes a separate plurality of registers for each of a win, place, show and also ran finish position. In accordance with the associated method, information representative of a particular finish position is tallied in an associated plurality of registers and decoded to determine if more than one of the racing members had finished within a predetermined time interval representative of a tie finish state.
If a tie is detected, a particular signal is produced representative of a double, triple or quadruple tie finish state. In response to this particular signal, the address of the registers associated with a different finish position is produced. This address is loaded into an address register in response to an enabling signal which is produced from the particular signal and delayed a period of time greater than the predetermined time interval. The address stored in the address register then activates the associated plurality of registers in the memory to receive the information associated with the next finishing racing member.
