Description

The Quadcolor has twice the memory of a standard CGA board (32k, compared to 16k),[1][2] and offers a 640 × 200 mode with two freely definable colours.[4] If used with the Quadcolor II enhancement board, the additional memory can be used in graphics modes to double the color depth, allowing for two additional graphics modes — 320 × 200 resolution with 136 colors, or 640 × 200 resolution with 16 colors.[2][5]

This card is supported by Dr. Hallo II and Turbo Pascal Graphix Toolbox.[6][7]
