I have an iBook G3 600 (16 VRAM) that suffered a bad power surge and was left for dead (wouldn't boot, no lights on power adapter, etc). I recently tossed a different battery in it, and it booted right up - it apparently can no longer run off of the AC adapter or charge, but can run fine off a battery.
I've tried several DC-IN boards, but it doesn't fix the issue (and sparks, quite a bit) - I think the PMU is shorted out in a spectacular fashion.
I'm trying to use this thing for a media jukebox project, so I really don't care about portability at this point. What I would LIKE to do is lose the battery, then try to wire a power adapter through the battery terminals and power it that way - does anyone know if this might be possible? If anyone has a pinout for the G3 batteries, I would appreciate it.
