CGA

The Colour Graphics Adapter or CGA was one of the first graphics adapters available for Personal Computers and was released by IBM in 1981 at the same time that they released their first Personal Computer. The CGA graphics card supported a single text mode display of 80 columns and 25 rows, and two graphics modes of 320 x 200 pixels in four colours and 600 x 200 pixels in two colours. The CGA was based upon the Motorola MC6485 video controller.
