Abstract
An electronic counting system with a solid state chip circuit having a multiple purpose counting and control system with an input signal operated control circuit selectively operable by input control signals from external circuitry for providing multiplication, division and rate computation functions and counting and two-stage predetermining functions, and also selectively operable by input control signals for selectively operationally partitioning a BCD RAM of the chip circuit into two separate RAM sections having selected numbers of BCD decade sets and operable to provide independent functions or interrelated functions. Data may be entered into each BCD decade of each of two BCD decade registers of the RAM directly by BCD and entry select signals applied to the chip circuit or by push button and entry select signals applied to the chip circuit.
