ABSTRACT:
A bit-mapped graphics terminal capable of displaying graphs as well as text permits character and screen attributes to be controlled with minimal memory requirements, and is capable of operating as an interlaced display and as a non-interlaced display. A first memory stores a display bit map that defines characteristics of individual picture elements of the display. A second memory stores attribute information for individual groups of the picture elements of the display.
