Jeff,
Any hints about these delicate soldering jobs - any special eye-wear, hand-steadying devices, soldering iron wattage and tip?
Sorry for the month late replies. I didn't read these messages originally, because of finals.
To touch up surface mount solder joints I use a 15 watt grounded soldering pencil available from Radio Shack for under $10. I like to use Chemtronics desoldering braid for removing old solder. Many places, including Radio Shack sell other brands of desoldering braid, and I don't understand why there's a difference, but my experience is that the Chemtronics brand is just way better at actually doing its job and adsorbing solder.
Eye wear and hand steadying devices depend on the individual. I'm approaching middle-age so I often resort to a 5X magnifying loupe/cup of the type you can hold in your eye by scrunching it into the skin around the eye. This messes up your depth perception though, so be careful. I had an interesting burn on my nose for a while...

The interesting thing happened when I reassembled it and powered it up: 5 of 6 slots were visible in the Apple System Profile!
Then I run Cubase VST 5.1, and I were able to =ABsee=BB and configure the audio
cards without problems. Until... Cubase bombed with a "bus error" and an
error type 10. I rebooted, and surprise: the cards weren't =ABvisible=BB
anymore, nor in ASP or in Cubase. Later, after having shut down and powered
on again the Mac, the cards came back to visibility in ASP... but after a
while, while I was inspecting the different tabs of ASP, exactly when I
returned to the tab showing the PCI slots population, the Mac showed an
error type 10 message and I had to reboot. After the reboot: cards invisible
again.
This sounds like bad solder joints to me. You've probably got some pins or pins on the Bandit or the arbiter which are making good contact and then not making good contact depending on how the board is bent and/or heat stressed.
Given that you had some slots working and others not working, I would guess that the problem is on the arbiter. The pins on the Bandit are all bus pins and if any of them are bad, the whole bus won't work. The pins on the arbiter are (mostly) slot specific, so you can disable different slots by interrupting certain pins on the arbiter.
Although it could also be the clock buffer pins...
In the meantime, in fact, I've bought an used 9600 on eBay for 145 Euros:

Which probably makes this posting late and irrelevant. The 9600 uses a different arrangement of power supply connectors than the 9500 though.
I hope this will fill my need of six functioning PCI slots... although I'm a
bit concerned for what Ron said ("some PCI cards need to be in the
controlling slot"), since I don't know which of my cards need to be inserted
in the controlling slot (and if).
There's no such thing as a single controlling slot. All Apple Mac PCI slots are Bus Mastering slots.
Anyway, I'm curious: does ASP show empty PCI slots as well?
ASP does not show empty slots, in my experience.
