My 2400 died again with click-of-death symptoms last week. The last 
time this happened I was able to (apparently) track the problem down 
to a faulty or damaged CPU daughterboard connector, which I fixed by 
replacing the entire CPU daughterboard (with a spare one provided by 
a kind ex-Duolister).

This time the starting symptoms seemed a bit different, and the CPU 
board seems ok (tough as it is to tell). However, I now find that one 
pin of the I/O daughterboard connector has become damaged - broken 
off partway on the main logic board side. What I'd like to decide in 
the immediate term is whether this pin and connector could be causing 
the failure to boot (click of death) on its own, or whether it 
represents something more esoteric like part of a port connector (or 
nothing at all). The failure to boot may have another cause entirely, 
particularly since this isn't the first time (for this 2400 or 
others).

So the question is, does anyone know what pin 125 of the I/O board 
connector is for? I'm rather short of computing resources without the 
2400, so it's difficult for me to check the service manual PDFs, 
assuming they even have the info.

Also, would anyone happen to have a spare main logic board from a 
2400 dead in some other fashion? Assuming that's what turns out to be 
the problem here. I'm obviously not planning on investing a great 
deal more money into this machine, but there may be something more 
financially feasible I can do other than simply buying an iBook.
