	What is this, a new PC?  What do you mean by "Unix port"?

	AT&T has two new video boards: the VDC400 which is functionally
	identicle to the built in video board of all the previous
	machines, and the VDC750.  The VDC750 has all the modes of the
	VDC400 plus EGA.  The VDC400 is the standard equipment on the 
	new PCs and is compatible with the 318H monitor.  The VDC750 
	requires the 319 monitor, which is new.  I believe it is a 
	multifrequency type to allow it to handle the 400 line AT&T
	mode or the 350 line EGA mode.  I believe both boards are made
	by Paradise.

	The DEB standard is not offered on the new boards but AT&T
	still supports it.  The DEB itself is no longer made (*I 
	believe*).  It seems funny that AT&T is just now offering EGA,
	(and a new monitor for it) when everybody else is jumping on
	VGA.  VGA may be in the near future, especially if Paradise
	is making cards for AT&T.  Having seen EGA and the 400 line
	mode side by side, EGA is a step down.  VGA looks great though.
