Hello again, tFer
My thoughts on your latest:
I am finding it hard to give up on this problem ...
I understand. I, too, enjoy troubleshooting and solving problems when time permits.
... am wondering if you'd recommend my resetting the PMU, and/or ... camera's light goes on and the whirring sound ... Firewire ... reset it ... Any extra info ... apart from the ones extended so far?
Re-read the previous posts in this thread. Everything you are talking about here has been recommended, explained, suggested, etc., in the earlier posts and the links included in them.
If you have not already done everything already suggested, now is the time.
Classic has NOTHING to do with iSight.
It is way too hard to part with my iSight ...
If you can get your money back, you might want to rethink that.
For a couple of years now, my posts have been cautioning about buying used iSights without testing them
first.
Click here for a few examples.
External iSight is a good webcam, but you have no idea how the one you bought was used or treated by its previous owner(s).
Moreover, anything people build can fail and need service. I like my external iSight, and I will continue to use it as long as it lasts, but I would not buy another external iSight if I needed a webcam today and Apple could not repair my current iSight at a reasonable cost.
Instead, I would choose one of the reasonably-priced, guaranteed, new webcams that work with my Macs. However, that is merely what
I would do. You should certainly buy what you want for your purposes.
... new cam (or machine) is way out of my budget ...
If you can get your money back from the iSight that does not work, you may be able to find a useable camera for less money than you paid for an iSight that is not working. (If you bought a used iSight for less than $US40, you should not be surprised that it does not work.)
Because you use OS X 10.4.11, your iBook G4 can use alternative webcams, including the new "UVC" webcams, some of which are low priced. These current "UVC" cams are widely available, and they will work on your 10.4.11 Mac with iChat and Skype. Just be sure any new webcam you buy meets the "UVC" standards so they work with your Mac's OS without addition of third-party drivers.

... Apple support is virtually non-existent where I live.
Re-read the top of this thread. I have already provided worldwide info on how to contact Apple by telephone, email, and internet for service if you choose to have your used iSight tested and/or repaired.
... I will certainly keep you posted on any miracles!
We will watch for your status update and contributions.
