The embodiment of the invention disclosed herein is directed to a solid state monetary accumulator, credit storage, and selector logic circuit which includes a plurality of flip-flop memory circuits for registering information corresponding to the value of coins inserted into a coin receiving mechanism, and for totaling the accumulated value of such coin accumulation to a predetermined maximum amount. Selector memory circuits are incorporated to enable a number of selections from a vending machine, such as a tape player juke box, so that selections can be made corresponding to the total value of coins inserted. Each of the flip-flop memory circuits is formed by a pair of crosscoupled logic circuits of the NOR type and have capacitors connected between the output terminals thereof and ground potential.
