Abstract
Solid state circuitry for a coin operated terminal adapted to be located remotely from a data base is described. The circuitry includes timing devices for limiting the duration during which the terminal can be used upon receipt of a coin and for returning a coin to the customer in the event no data is received from the data base. The terminal is provided with a communications modem and interrogator for accessing the data base. During the interval in which communications is being initiated, the terminal keyboard is locked out of operation so that the customers cannot accidentally disrupt or scramble the interrogator signals.
