<p>The system has a data input unit (10, 11), a data storage unit (13a, 13b) and a data transfer unit (12) to take data from the storage unit when the input unit is not operating and to take data from the input unit when the latter is operated. The data input unit pref. has a keyboard (10). Pref. there are two storage units and a decision unit which determines from which storage unit the data should be taken. For use with e.g. a cash register, the system may have input registers for presetting and storage of classified articles, a memory for infrequently occurring articles, and accumulators with selectors and an instruction sequence circuit.</p> |
