I found this card that uses the same chip and has CGA composite output:
(Source: http://oldcomputer.info/pc/board_gfx1/index.htm)Can it be used to reverse engineer my card to output CGA composite?
Probably! If you can trace the lines to see where everything goes. It's possible (although difficult) to do this from images (I've done it once before) but much easier if you can use a multimeter's continuity mode.
