Abstract
A palette device controllable by a digital computer with a video memory to produce signals representing color for a video monitor. The palette device includes a multiple-bit input latch for entry of color codes from the video memory, and a look-up table memory for supplying color data words in response to color codes from the input latch. A digital to analog converter responds to color data words to produce an analog color signal. Selection circuitry connected to the input latch and to the look-up table memory supplies the digital to analog converter either with a color data word supplied by the look-up table memory or with a color data word comprised of color codes from the input latch. Improved graphics computer systems, facsimile systems, printer systems and other systems and methods are also disclosed.
