ABSTRACT:
To permit multiple use of data entry keys, and to effect different circuit connections by a single key, operation of any one of the keys is associated with time slots, or time windows so that, upon operation of anyone of the keys, a course, or sequence of time slots at intervals is initiated, each interval or time slot being temporally associated with a specific circuit connection. The length of the time course, that is, the number of time slots or time intervals is selected by continued operation of anyone of the control buttons, this continuance of operation or operating of another button, entering the then pertaining circuit into the system. An indicator is provided, continuously indicating the then pertaining time slot, and an additional indicator providing a symbolic output representative of the finally established circuit connection. The system may be used with a graphic display, such as a pointer pencil and a screen, the circuit connections establishing representation, sequentially, of electrical components which sequentially appear on the screen at the location indicated by the pointer so that, upon removal of the pointer, the then indicated symbol will persist on the screen, thereby permitting rapid interchange of components and electronically drawing electrical circuit diagrams.
