those are perfectly normal early PPC "chimes of death" from the description. But he states that the death chimes are producing irregular sounds, so how can it be normal?

First video, 4 seconds in, but a tad slower. Mine also repeats it in not harmonizing tones after the first time.

Mine also repeats it in not harmonizing tones after the first time. Yeah that's pretty screwed up. Definitely not normal as Bunsen pointed out.
My only guess is there's a bad cap of some sort near the sound chip or your logic board is fried.
Do you get an error code when the death chime sounds? Or do you just hear the audio (no video)?

Need to watch the clock pulse running through the system with a scope/frequency counter. its acting like your system bus clock is REAL slow. or noisey.

No video or error code at all.

Seems to me that you Duo is already dead, and not in the process of dying anymore.
I think you're better off finding another Duo, unless you can perform miracles. 😎

If it's just the MoBo RAM that's dead, maybe it'll help to disable those ICs . . .
. . . and run with JUST the expansion card? :?:
I've been looking at this option in order to steal the Bank Select Signal from the Mac's traditionally pathetic ration of onboard RAM to address a Hacked Memory Bank. }🙂
Dunno if the ROM's Memory Mapping will support supplanted MoBo RAM . . .
. . . but a Virtual Memory Enabler could work wonders! :approve:
