Abstract: DISPLAYS HAVING DIFFERENT RESOLUTIONS FOR ALPHANUMERIC AND GRAPHICS DATA A display terminal presents alphanumeric and graphic data at different resolutions simultaneously. The durations of the individual alphanumeric and graphic dots have a fixed but non-integral ratio to each other, and are mixed together asynchronously to form a combined video signal to a CRT.

Abstract: HARDWARE GENERATION OF STYLED VECTORS IN A GRAPHICS SYSTEM Vectors on a graphics display are styled according to a specifiable pattern of on/off segments at the same time that they are drawn on the display by integrating the styling of each pixel on the vector at the same time the location of that same pixel is determined according to Bresenham's algorithm.
