Happy end of year everyone!
Unfortunately, I'm still having problems with my old Mac Pro 1,1 (successfully flashed to a years ago 2,1).
So: my Mac Pro died, most probably in consequence of a power surge after I turned off the power bar without noticing that the Mac was still on. It was very late and... anyway: I bought a 'new' used 1,1 and I'm good to work now, but nevertheless, I'd love to repair my old machine. So I purchased a used original, "working" PSU on eBay. Unfortunately, still no reaction whatsoever when I press the power button.
I could start to swap parts between the working and the broken Mac Pro to see what component doesn't work (I'm still not sure the 'new' PSU really is okay, btw., but before I do that, albeit endangering the health of my only working machine, I'll rather ask the experts in this forum what they believe could be the problem. Could it be the Front Panel Board? Is there any way to find out by 'jump starting' the Pro while bypassing the power button? What else could I check out before ripping the working Mac Pro apart to check every part of the old machine in it until I find the one that's causing the malfunction?
Note that I'm trying to start the old Mac pro without Memory Raisers, Front Fan Assembly, HDs/Disk Drives and CPU fans. I suppose that should not be the problem in order to check out if it's powering up, or should it?
