ABSTRACT:
Disclosed is a data entry and display system for loading any one of N digits into any position of an M position data bus where N and M are integers. The system includes a set of N pushbutton switches each of which is representative of one of the digits; and a set of M pushbutton switches each of which corresponds to one of the M positions on the data bus. The system is operated simply by first pushing one of the N pushbutton switches which corresponds to the digits to be loaded; and by subsequently pushing one of the M pushbutton switches which corresponds to the desired digit position. This sequence is repeated for each digit to be loaded. A total of M identical circuits, one circuit for each digit positions in the data bus, operate in parallel to sense the pressed pushbuttons and to take the appropriate bus loading and bus displaying action.
