As many of us probably know, the IBM Color Graphics Adapter exhibits "snow" on the screen when the CPU and the video refresh circuitry both access the video memory at the same time. The MDA, EGA, VGA, etc. don't have this problem. Why not? What's the specific difference which prevents snow on better display cards? Please email replies - I wouldn't want to bore the net (any more than this question already has ;-) Thanks! -- Scott Coleman tmkk@uiuc.edu "Unisys has demonstrated the power of two.
