TIME-SHARED APPARATUS FOR OPERATING PLURAL DISPLAY MEDIA, AND DISPLAY METHODS INCLUDING PAGING, DISPLAYING SPECIAL FORMS AND DISPLAYING INFORMATION IN TABULATED FORM

摘要

A cathode-ray tube display terminal having a single cathode-ray tube keyboard-monitor or plural cathode-ray tube keyboard-monitors which time-share a magnetic core memory, a symbol generator, a printer and an input/output section for two-way communication with a digital computing system. The digital computing system may select any one of the keyboard-monitors, or some or all of the keyboard-monitors to receive information. Methods are disclosed for displaying information in tabulated form, for transmitting and receiving information in excess of the capacity of the cathode-ray tube screen, and for displaying special forms which limit operator access to predefined areas of the cathode-ray tube screen.
