Know anyone who has tried it? I have one of those cards in my spare parts 
pile, along with a 24 bit nubus card. I was thinking I had tried it with
a IIgs monitor but can't remember. Mighta decided it wasn't worth risking
roasting some hardware since I'll never need to use 'em together.

Sounds kinda like this NTSC nubus video card I tried in the IIci mothballed
in my closet when I connected up a composite color monitor to it. It freaked
my eyes out and was kinda hard to use.
