Abstract
Abstract A computing device for a multiple product gasoline dispensing system having a cost counter for accumulating the cost of gasoline dispensed, a bank of three price decade switches for each gasoline product settable for establishing the amounts of the three places respectively of a three place unit volume price, and a pulse generator for generating a pulse for each onehundredth of a unit volume of gasoline dispensed. A sequencing circuit is operated by each pulse to sequentially set a binary predetermining counter at the straight binary complement of the amount established by each decade switch for the gasoline product being delivered and an oscillator is gated to index the predetermining counter from such setting to a maximum count and simultaneously index the cost counter to enter such amount into the cost counter at a level corresponding to its order of significance in unit volume price.
