Found an iMac at the side of the road on the way to work this morning. It's and Indigo and, based on the serial number, is a G3/500 (early 2001). The bad news is, it appears to be dead.

I initial tried powering it on and would only get a small burst of static from the speakers when I pushed the power button. I tried replacing the battery with a known good one; now, when I press the button I hear something like "Flup, Flup, Flup, Flup" from deep within.

Does this sound familiar to anyone?

Thanks...
