	I talked to Headland (Video-7) on the phone about their VRAM VGA
	card.  They said that they had 256 color drivers for the 640x480 and
	640x400 modes.  However,  they did not have 256 color drivers for the
	800x600 modes.  They said that it would be too slow. The Fastwrite
	VGA card also had drivers for the 640x4?0x256 modes.  These drivers
	are for both Windows/286 and Windows/386.  They do not yet have 256
	color drivers for OS/2.

>	Our application involves the display of grey-scale images,

	I have heard that VGA cards will not display 256 colors of grey due
	to the way the bits were divided between red, green, and blue. Anyone
	know?

	Please, post any information you get.  I am sure there is plenty
	of interest in this subject.
