Alright, here's what we got: A IIsi that won't show video. Have a real mac monitor, so we can take away all the hubub about getting a vga monitor to work.

Only shows a black screen. I know there's a system on it because I put the drive in my quadra. Everything with the hard disk is fine.

I know the memory is good because I swapped in my quadra's (700) memory. Still the black screen.

Can't be the PRAM battery, Cause I swapped that with the quadras and flashed the pram a couple of times.

Now I'm probably looking at a pretty serious hardware problem, I think, unless I'm missing something obvious. Any ideas?
