Abstract : Developed as a general-purpose program for the computer entry and manipulation of hierarchically-structured graphical information, the DX-1 Display System utilizes a drum-buffered scope, light pen and pushbutton box to provide the console user with the ability to draw charts, diagrams, curves, etc., on the face of the display scope. The drawings contain information which is reduced to a condensed digital format called an Entity Table. This table can then be manipulated by the use of special-purpose software during the drawing action. Graphical information generated by either console user or a conversational-mode computational program can also be displayed in full color. (Author)
