Is it supposed to be blowing air up into the computer or down out of the computer?

Exactly lol...very zen.

If you want to pay for the capacitors (roughly $50 of caps to recap the analog board, logic board and floppy drive.) plus shipping to/from Atlanta, I'd be happy to whip that sucker into shape. I've done about eight of these without any problems. I wouldn't charge for the work...that's just a...

yes it so happens the the classic analog boards are the worst of the worst in terms of leaky, unreliably caps. Just a bad period in time for capacitor manufacturing and the Classics were in the heart of it. Main thing though is get that nasty, nasty ugly lithium battery off the logic board...

99.99999% just capacitors have gone bad on the power board and possibly the logic board. If you want it to work again, you've got to replace them or have it done. All Classics and Classic II's need to be recapped. They ALL fail this way. 100%. There's a slight chance it's a damaged video chip...

ah..the 7200/90. The first Mac I ever bought with my own money back in 96 I think.

Wondering what the prospects of finding one of these are , if they exist or if I should bother trying?

Sorry to hear this. Mistakes happen and we've all made them. Hope you can get the board working and whatever you do, certainly do not chuck it. There are many parts on there which are still fine and could contribute to another troubled board.

Put UV mask on the traces under C10 on my SE/30's. No reason not to.

Will do. Thanks.

excellent. Thanks.

Oh cool!...was there a thread with the firmware commands?

Thanks. I'll check out the video chips. I believe mine is the first revision (PowerBook6,1). 867mhz with mini VGA.

Should be connected.

Wait...I'm confused. Are we saying the C11+ to DFAC pin 2 on the schematic is incorrect or just that via? Sorry if I'm slow on this...I just double checked the continuity of all the caps...I didn't have continuity from C11+ to DFAC pin 2 (I checked it six times). No visual sign of a broken trace...

Incredibly helpful. Thank You!

44 Capicitors later... got everything working.

Fixed it! C9 had a broken trace. Thanks for your help!

thanks ..yes the egret chip is the most corroded on the board. I've been working on it but it's still not looking great.

Thanks. Which one is the egret chip?
