^^ I was referring to the ring of light (provided by LEDs) on the power plug.
Anywho, yeah, I'm actually using one of them now. It's INSANELY fast. For some reason, Apple updated the system controller for the final 1.67GHz PowerBooks (the HiRes/DL SD models), as it uses DDR2 RAM and has a few other niceties not present on even the previous 1.67GHz models. Taking into account the terribly short lifespan of these machines, it's surprising: the TiBooks subsisted on essentially the same UniNorth and KeyLargo controllers from the original 400/500MHz model to the final 1GHz version, which was a couple of years. Perhaps Apple was considering moving to a derivative of one of the dual-core G4 chips Freescale was cooking up prior to the Intel switch...
For some useless trivia, although everymac.com lists these things as utilizing the 7447A, according to the etching on the die itself, it's actually a 7447B (I have pictures, I'll upload them eventually).
I also managed to repair both of the SuperDrives. I curse Panasonic (Matsushita changed their name to Panasonic sometime in the last three years or so) for making these things so cheaply: the mechanism used to drive the laser assembly utilizes an unreasonably thin and flimsy plastic bit to mesh between the laser assembly and the screw drive (it's pivotal as it converts rotational movement to linear movement), and to top it off, they didn't even put any lube on the thing.
I cannibalized an intact plastic dealie from a flaky Matsushita CDRW, and that fixed one. The other was repaired with careful application of the best adhesive EVAR, JB Weld. I used the JB Quik stuff for this, and it held up perfectly. I'm very happy about that, as the drives exhibit no malfunctions otherwise.
I'm still slightly hesitant to spend any more money on them, as it may be some sort of ridiculous logic board failure and not a DC board failure; I mean, Apple's early/mid-2000s stuff was, unfortunately, very prone to some sort of issue. These, for example, were often stricken by the lower RAM slot failure...
But this thing is just SOOO fast that, regardless of the dings in the case and the uncertainty of where the true failure lies, I may go ahead and buy a DC board. If it doesn't work I can resell the new DC board, and then attempt to get some cash for the displays and other miscellaneous parts. Or I could try to find a ~1MΩ resistor and attempt to permanently install the circuit that makes these things boot...
