A few months back we got hold of several PCjr color monitors at a bargain
basement price.  We quickly adapted them to connect to a PC color card.
It'll take about a half hour of your time to hack the PCjr connector off
the end of the cable and put a 9-pin male connector in its place.
To keep things simple, I'll draw you a picture of how it's wired:

					   pink,  braided
			blue   green  red  grey,  shield
					   clear
			  ___________________________
			 /			     \
		PIN 5	|  o     o     o     o     o  |  PIN 1
			 \			     /
		  PIN 9	  \   o     o     o     o   /  PIN 6
			   \_______________________/

			 yellow  brown  (open)  orange

This is the view as you look at the pins to which you solder the wires,
*not* as you look into the open connector end.  Note that one pin (7)
is unused, and another pin (2) has three wires connected to it.  Actually,
you might want to ground pin 7; I think that was the sound input.
If you leave it open, you'll have to turn down the volume on the monitor
or else you'll get a rather obnoxious buzz (kind of like Flight Simulator
sound effects).
