ABSTRACT:
There is provided a micro-computer driven random data selection system. The processor of this system is arranged to read a matrix of switches to determine a range of numbers and to establish a software controlled sequencing routine corresponding to this range. The interrupt terminal of the micro-computer is used to sense the activation of the system and causes the number selection. The software of the present invention presets the internal counters to the requisite range in response to the status of the switch matrix and displays that range in one of the two LED displays. Following sensing of the range, the computer starts the sequencing or counting and continuously sequences until deactivated. When the "roll" switch is operated, the computer samples and displays the last number in the sequence. Data for controlling the displays and loading the counter is stored in memory locations and the address for this data is developed from an index generated from the switch matrix inputs.
