I think you should try something called a 'Grey-Scaler' (sp?). I saw this
thing in a recent issue of Computer Shopper. The review was pretty favorable.
It is designed to meet your exact needs so you might look in some back issues.
( sorry, mine is gone so I don't know the issue or the manufacturer ).

Also I've never actually used this so I cant personally vouch for the product.

As I remember, it cost only $30.00 or so .

Another option you have (a quick fix but not the best ) is to wire a simple
connector to send the sync and *one* of the color signals. The chosen color
signal will be used to drive the vidio input of your monitor. This has worked
for me in all the times I have needed it ( usually when the mono monitor is the
only thing running ). I used the green vidio signal, I'm not sure why...
The major drawback is that any vidio  that has no green in it will not be
displayed. This is bad for some games and provides no real grey scale. You will
have to run things like procomm in mono mode or some of the menus will not
appear when summoned.

I hope this helps. BTW, I am associated in no way with the company or products
mentioned above nor am I affiliated in any way with any South American cartel.
