Okay, not sure what's going on here, and I'm hoping someone might have some idea before I dig into it and find out what's going on. For background: 500mhz G3(stock) 1gb PC-133 Mostly dead battery in left hand bay DVD-ROM on the right I had it booted into OS 9, and it was running fine. I was preparing to attempt to install OS X Server 1.0 onto my GigE via TDM. I had the GigE booted into TDM. As soon as I connected the FW cable to the Pismo, I heard a pop and "let the smoke out" of something. The computer turned off, and it got VERY hot on the bottom, near the Apple logo on the bottom and just a little behind the FW ports. I pulled the battery and unplugged it. After a few minutes, I got brave and tried powering it on again. The computer chimed, and the screen flashed gray for a moment before going blank. I heard something that sounded like sizzling, accompanied by the same spot on the bottom getting warm. I immediately powered it down again. I also heard the hard drive spinning. I'm thinking(and hoping) that maybe I just popped a cap and can repair it. The fact that it powered on and chimed is encouraging. Without tearing into it and pulling the logic board, does anyone have any thoughts as to what I might be dealing with? I may try tearing it apart this evening just to see if I can get a visual diagnosis.
