Early Grocery Store Level Efforts by IBM

The Transaction Recorder was an attempt to develop a mechanical register and is the earliest system I know that IBM worked on. In 1968 or earlier IBM worked on it but it was not sufficiently cost effective to become a product.

1968-1969 The 29SM (SM meant Store Machine) followed this and was developed in the San Jose plant and installed in a Safeway store in Fremont, California in 1969. The test was successful and the marketing division wanted to go to market. That was over ruled by the Development Division and Corporate because of coming store technology. The 29SM was based on an IBM 1130 processor and IBM OPD 632 systems for the keyboards. Products were coded in something similar to PLU numbers used later but tuned to enhance key performance

1969 - 1971 Development of a third store effort, known internally as "Pebble Beach" followed this in the San Jose Plant and was based on a System /3 processor. Unfortunately, development killed this when they learned about new microprocessor technology known internally as the Universal Controller. After this store systems development moved to Raleigh.
