Red is on 3, Green is on 4, Blue is on 5, and Grounds are on 16
through 20. Wire on 75ohm resistor from Red to Ground, one from
Green to Ground, and one from Blue to Ground.
I once made up a custom, adjustable terminator for a guy who wanted
his RGB-viewed colors to match his NTSC-viewed colors. Rather than
use a 75ohm resistor for each color, I substituted a fixed resistor
(51ohms) in series with a potiometer (50 or 100ohms) to allow
tweaking the colors to match. You end up with, say, one terminator
being 70ohm, one at 80, and one at 85. It worked great.
You 1084 will scan at 15.7kHz only. Its forte is the ability to
display composite, Y/C, and component video signals. You can
literally find 31kHz monitors anywhere these days, cheap too. With
your built-in de-interlacer/scan doubler, you should be able to get
by without any 15kHz RGB monitor, which are getting hard to come by.
If you want to cover your bases, use the 1084 as your Toaster Preview
monitor, keeping it cabled to both your RGB port and the Preview
BNC. With a push of a button, you will be able to switch back and
forth. The 1084 also takes care of the termination problem.
