ABSTRACT:
The invention pertains to a method and apparatus to provide for the display of characters and graphics in color. The invention includes three bit map memories which store graphics information for different colors, one character generator driven from a text memory for display of text, and an attribute memory for storing display characteristics such as inverse video and blinking. The contents of the bit map and attribute memories and the output of the character generator are used to address a pre-programmed ROM. The output from the ROM is a string of three bit words with each bit stream representing a primary color on a color CRT and being connected to the associated color input to the CRT. Composite graphics and text are displayed on the CRT.
