Abstract
A digital toy which produces a random response to an audible inquiry. During the time of the audible inquiry, a switch is depressed. During that switch depression time a random response of the yes or no type is determined and at the same time an enabling signal is generated so long as an audible inquiry has been detected. Upon release of the switch the enabling signal causes binary coded decimal lights to flash and simultaneously tones to be sounded for a time period followed by a buzzer sound after which the predetermined response is displayed.
