If I start the PC using the software, if claims to be running. I hear the PC beep indicating it’s starting, but screen is black. Switching to Mac works. Switching back to PC it’s just a black screen. Card gets untouchably hot.
A few ideas I have:
(Simple to obtuse)
• You’ve got the four ended cable, not the three?
• Have you tried with no SIMM, just using shared RAM from the host machine?
• Is your preference set to fade the screen when switching? I’ve heard the switch doesn’t always function properly if not set to fade.
• If running in a Quadra 9x0, the Serial Switch control panel may need to be set to compatible mode.
• I’ve heard some make reference to a “6100 version” of the adapter cable. This could just be differentiating from the PCI models’ later 3-ended cable, as I’d suppose any such version intended specifically for the 6100 would’ve had HDI-45 connector instead of DA-15, and I’ve never seen one like this. The clunky adapter-fest usually gets comments for being a known factory requirement when run with a 6100 and AudioVision 14.
• Now that I know it exists, what is the status of your cards in regards to the jumper
@dr.zeissler pointed out?
• Tried swapping for a known good 486 chip?
