Hardware entity

A graphics adapter introduced in 1981 that supported 4-bit color (16 colors) and resolutions up to 640×200, superseded by EGA (introduced in 1984).


The first video game about Color Graphics Adapter was released in 1981.

Two palettes were used:
* magenta, cyan, and white
* green, red, and yellow
... both had black as default background color, but this could be changed.

CGA did not support customized color palettes like the later video adapter standards.

CGA adapters were connected to the monitor via an RCA jack.
