    Abstract: A computer terminal includes a cathode ray storage tube for receiving information from a computer and storing the same for continuous viewing. A copying apparatus is employed for making a permanent copy of the information presented on the cathode ray storage tube screen, such copying apparatus including means for scanning a sensitized surface, later suitably developed to provide the permanent copy. Read out circuit means effects simultaneous scanning of the copying apparatus and the cathode ray storage tube at a relatively slow rate compatible with the scanning capability of the copying apparatus, while at the same time the cathode ray storage tube''s electron beam is pulse modulated wherein each pulsation thereof has a duration shorter than necessary to write information on the storage tube. The resultant signal produced at the storage tube target is coupled to the copying apparatus to duplicate the information stored on the cathode ray storage tube screen.

    Abstract: A system is shown for monitoring a direct viewing bistable image storage cathode-ray tube with a cathode-ray monitor tube in which the monitor tube visually displays stored writing when the storage tube is operated in its storage mode and nonstored writing when the tube is operated in a nonstore mode. The nonstored writing is displayed on the screen of the monitor tube with improved intensity and in a manner which insures that the complete image visible on the phosphor of the storage tube is reproduced on the screen of the monitor tube. This is accomplished by providing a circuit which maintains both a readout raster on the storage dielectric of the storage tube target and electron flood guns in operation while at the same time maintaining a potential on the target backplate below that necessary for the storing operation but at a value which causes the nonstored writing to have a controlled persistence lasting for at least the time duration of one frame of the readout raster.
