	The VDC400 is (basically) what is in the 6300 as standard 
	equipment.  The VDC750 will not work in a consistent fashion
	in the 6300.  I would imagine that it would work no better or
	worse than any other EGA card although I have no experience on
	which to base this.

	Never heard of 64 shades of grey from the standard hardware
	but don't forget the 640x400 proprietary monochrome mode.  There
	is no Hercules support in the standard system or DEB.

	It's more complex on older PC6300s.  You should also
	(hopefully) get the EGA mode of 640x350 16 colors.

	No, there is also the STB EGA Multires II as well as some
	other possibilities (I think that Magnavox, and TAXAN may 
	make EGA cards that have 400 line, 25Khz output but I am
	not sure.
