AND THE ANSWER IS...

Motherboard! Aka backplane.

I replaced everything else inside the box except the tape drive and DVD and control panel. So now I have lots of spare parts :-)

Thank God for eBay. All these parts were pretty cheap. The motherboard was about 300 bucks. So I did a manual IPL, and then I left for a while and when I came back it was back to the manual IPL initial screen. So I'm going through my second manual IPL. Not sure if we lost power or if something else burped that caused it to reboot. I won't be surprised if I have to boot off the DVD and reinstall the microcode in the firmware. But the good news is

ITS ALIVE.

Congrats!

I wonder which specific part on the "main planar" might have caused this, though.

:wq! PoC
