ABSTRACT:
A point-of-sale terminal system including one or more keyboard terminals and associated cash drawers in communication with a control chassis having a micro-computer, a printer and power supply. Each keyboard terminal has manually operable keys for designating the various items for sale and associated display devices which, under the guidance of the computer, display the number of each item ordered. Function keys are provided for instructing the computer to total the sales price of each order with automatic tax calculation. Provision is made for the temporary storage of one or more orders with a recall feature that redisplays the order. Numeral keys are provided at the keyboard to give an alternate method of incrementing and decrementing item quantities and to provide means for effecting price and tax changes. Order changes may be effected at any time prior to the total sales price calculation that enters the sales price and item quantities into the computer's permanent memory.
