The Color Graphics Adapter (CGA), introduced in 1981, was IBM's first color graphics card (originally sold under the name "Color/Graphics Monitor Adapter"), and the first color computer display standard for the IBM PC.
The standard IBM CGA graphics card was equipped with 16 kilobytes of video memory, and could be connected either to a NTSC-compatible monitor or TV via an RCA jack, or to a dedicated RGBI CRT monitor. Based around the Motorola MC6845 display controller, the CGA card featured several graphics and text modes. The highest resolution of any mode was 640×200, and the highest color depth supported was 4-bit (16 colors).
