I got the replacement CGA card in today and it works with a couple of things happening. The first is that if I launch the norton commander, there is a significant amount of snow going on, little red horizontal lines briefly if I hit Ctrl-O to make the menus come/go away.
Also, if doing scrolling like a long directly, the top half of the display blinks very quickly between the image and black.
It is definitely slower than the EGA card, but no more issues with software taking it into EGA mode with the CGA monitor at least.
Are these things normal with CGA?
