Im using a gdm1961 (DEC RGB sync-on-green flavour)  which needed only a couple of resistors
and two bridges removed to make it accept the H and V syncs.  If you dont mind experimenting,
you could use 3 75ohm resistors to make a 'Y' peice, connect a sync to each and the final to the
composite in.  Google can help you find the modelines.  Mind the sync polarity, depending on how 
you mix them.

The fun bit is getting the modelines right.  I have 1600x1200, 1280x9??, and a couple of the 
lower ones working, though they appear squished.

It doesnt replace the old applevision 20 that died recently, in terms of friendlyness.  The colour convergance
is out in the corners when fine in the center of the screen.  Inside are two dozen trimpots, but it
doesn't 'remember' different settings for each resolution.

Otherwise, they make alright old displays (great for DVDs).

Cheers,
Marco
