IBM PGA was compatible with CGA only. Matrox had a PGA compatible board that had a better text-mode CGA emulation (twice vertical resolution). However, the compatibility is a bit peculiar: CGA screen can coexist with the PGA screen, and you switch the display with a simple I/O operation. Just as if you had two cards connected to a single display through a switch. Matrox CGA emulation wasn't very good in graphics mode. Microsoft Word had problems with it. -- Adam Mirowski, mir@chorus.fr (FRANCE), tel. +33 (1) 30-64-82-00 or 74 Chorus systemes, 6, av.Gustave Eiffel, 78182 Saint-Quentin-en-Yvelines CEDEX
