The functional objective of the Supermarket System is to provide complete shopper checkout and store support facilities and to capture vital operational data at the point-of-sale. The system consists of a store controller and point-of-sale terminals that communicate with the controller through two store loops (maximum of 12 terminals per loop). The controller is capable of batch communication with a System/370 host computer on a switched line. The controller can also provide back-up foar companion (remote) store whose controller has failed. Communication with the terminals in the remote store is through the store loops in the remote store and a switched line (for a detailed description of the system, see the paper by McEnroe, Huth, Moore, and Morris; and of the scanner, see Dickson and Soderstrom).
