This is why I always like to work with older hardware and never upgrade to better systems. Crap always refuses to work.
In this case, I got a Powermac 9600 that was "Avid Ready" (had an Avid video I/O and compression board installed) and after I moved most of my hardware from my 8600 (cards, drives and ram), I tried to upgrade the system. Of course, that has so became a day of fun.
1) I bought an untested Sonnet Crescendo G3 400/512 card for me to put in it but when I do install it I get no chime or anything. The card warms up and yes I have tried both the CUDA switch and a PRAM reset but still nothing happens. I have a suspicion the card itself is dead or there is something elsewhere on the board (the ram?) that's causing the issue but I don't know what it is.
Also, did this model come with a circular screw-on heatsink or should it have the purple one that most other Sonnet cards have?
2) I have an OrangePCi 540 card that worked flawlessly in my 8600. I was expecting it to do the same in my 9600 but nope. So long as the card is in the box I get no video signal and the system does not even try to boot blind.
3) I prepared a Radeon 7000 for use in this box but that problem is being discussed in another thread.
What's so special about the 9600? I see there is an empty ROM slot in the board but would that help much and what would it do?
