ABSTRACT:
A device that produces a first response when its operator has successfully matched a pair of specific stimuli from a plurality of stimuli available for matching, and a second response when the selected stimuli are not a match. The stimuli available for matching are grouped into two (2) separate and distinct groupings, and one of said groupings is sub-divided into a plurality of sets. Both groups of stimuli are encoded in BCD form. All of the sets in said sub-divided group of stimuli are stored in the memory of a PROM, and a selector switch re-calls a specific one of the sets from the memory of the PROM when it is desired to attempt to match the stimuli in such selected set with stimuli from the first, unsub-divided group of stimuli. A comparator means performs the matching function to determine whether the device operator has successfully matched the stimuli from the first and second groups.
