Rich -
     No; MCGA is a 400-line version of the CGA card with a couple of extra
features. 1) It double-draws each line in any of the normal graphics modes,
much like the FlickrFixer does for lower-resolution Amiga screens. This
eliminates those annoying scan lines. 2) It provides an enhanced, VGA-quality
text screen. 3) It provides some extra graphics mode, the exact capabilities
of which I don't know; I've been told several different things by several
different people who ought to know what they're talking about but keep 
contradicting each other :-(. I THINK the extra modes are 640*200, eight
colour, and 320*200, sixteen colour. (These could be wrong).
     At any rate, as far as the monitor is concerned, MCGA has the same
scan rates as a VGA screen.
