So far, nothing


Okay, after trying out all three cards on my G4 400 tower, no dice.  The apple card was detected by PCsetup, but with no video pass through cable, and no floppy, progress was severely hampered.
On the OrangePC front, the problems start at the application level.  I was only able to start up the OrangePC program once without the whole computer freezing up!  'Macs just work', meh...
I'm currently using Mac Os 9.2 with an install of Os X on the same drive. Going to start off by performing a clean install of Mac Os 9.0 and no Os X, and try again.
Fingers crossed!!!
