Okay, I have been running saying that the VGA memory area is at A000,
right?  And this is above 640K....but what about systems with 512K?  Where
do all the ROM extensions and stuff go?  Are they on the cards?  If they
are, is that memory above 640K really there as far as applications are
concerned?  Couldn't you recover it for use with applications?

Just wondering,

Brian
