ABSTRACT:
A magnetic storage supplies binary input signals representing characters and a synchronizing signal. The binary input signals cause the intensity of the beam in a cathode ray tube to change from a first to a second intensity value. The beam is deflected over predetermined areas on the screen of the cathode ray tube by the synchronizing signal. If a beam of the second intensity value impinges upon a given area a visual output signal is generated.
