Multi-Color Graphics Array

The Multi-Color Graphics Array or MCGA was a video subsystem built into the motherboard of the IBM PS/2 Model 30, introduced on April 2, 1987, and Model 25, introduced later on August 11; no standalone MCGA cards were ever made.

The MCGA supported all CGA display modes plus 640×480 monochrome at a refresh rate of 60 Hz, and 320×200 with 256 colors (out of a palette of 262,144) at 70 Hz. The display adapter used a DE-15 connector. The MDA monochrome text mode was not supported.
