[comp.sys.next] Yet Another Product Review

	I just got the RGB 111 video adapter from Extron Electronics.
We wanted to be able to project NeXT displays through our Electrohome
Graphics projector.
	The RGB 111 plugs into the cube with a very short cable to the
display output.  The normal MegaPixel display cable plugs into the
other end of the box, and R-G-B and Synch (or composite) come out of
the side.
	It worked just like a black box should:  quietly, and the first
time.  There are a few switches that can be twiddled from inside the box
(eg, sych on green), but we didn't need any of them.  The quality of
the graphics is as good as I've seen on a projector (other than big-$
ones like the Light Valves NeXT uses).  For $370, it's a great deal;
lots of simple-looking video converters are very expensive.
	One caveat: before buying any of these things, make sure
your projector or other monitor can handle the screen rate of the
NeXT:  I've left my notes elsewhere, but it's pretty high, like
53 or 63 KHz.  Scan conversion is another, more expensive, game.

	standard mumble:  No one I've ever known has anything to do with
Extron, except I talked to a salesman and placed an order.
