I'm beginning to think you're right, since I just powered it on and I get a 
blank 50% gray desktop screen -- no icon, no screen updating, just the 50% 
on-off-on-off default desktop pattern.  So I built some 6.0.8 1.44MB startup 
disks and the first one boots, loads, and definitely does about 30 seconds of 
*something* but I can't see what.  I tried moving the mouse pointer to the 
upper left and right, thinking that the display board turned the Mac screen 
into a "window" onto a larger virtual desktop, but nothing.

So, if this is a mono output board, what kind of DB9 mono monitor can I attach 
to it?  I've got an IBM mono TTL monitor next to me, will that work?  Or was 
there some goofy brand of high-res mono monitor this board was designed to work 
with?

Or should I just crack the mac and take the board out and sell it on epay?
