ABSTRACT OF THE DISCLOSURE A control circuit for vending and other coin controlled devices including a first accumulator for accumulating the price of each vend, said accumulator having a first input where signals that represent each vend price are entered, a second input where signals for initiating a vend operation are entered, a third accumulator input, and an accumulator output, a pulse generator having an input connected to the third accumulator output, said pulse generator having an output operatively connected to the third accumulator input, said pulp generator producing outputs to enter into the accumulator whenever a vend operation is initiated and until the amount entered into the first accumulator equals the vend price also entered therein, a second accumulator having an input operatively connected to the output of the pulse generator and including means to accumulate the total of all vend prices entered in the first accumulator, and a readout device associated with the second accumulator where the running total being accumulated in the second accumulator is indicated. The present control circuit may optionally include a reset control to periodically reset the second accumulator so that total net sales over any desired time period can be accumulated. The subject circuit can also include various types of accumulators including multi- stage binary circuits, adder circuits, shift registers, and ring counters to mention a few.
