Abstract
Abstract An input mechanism includes a plurality of input factor storage units for storing and coding pulses representative of input data. The stored data is transmitted to a data processor and to a decoder for subsequent display. Preferably, the number of storage units equals the number of display terminals on the display device. A selection device directs the pulses produced by a manually controllable pulse generator to one of the plurality of storage units.
