Good luck! I doubt to be successfull with mine, as the leaking PRAM battery was above the keyboard connectors and video part. The worst place ever!

Congrat ! Will try that Scratch Brush on one of my 3400/240 boards . Only tried with a tooth brush, and it couldn't reach every places.

Any update on the BIOS dump? Have you had any success? It'd be interesting to compare it with the "plain" Intel version and see where the main differences are.

I think I'll try the keyboard from my working PB 3400c first.

I used a fiber optics eraser first to remove the verdigris and then water and after that Isopropyl alcohol. But I forgot to look on the bottom side, although I held the logic boar…

Good to know. Thank you. I misread Techknight. I would clean the connector really well with Scrubbingbubbles... or whatever you use, since I know you said that's not possible …

To replace the keyboard connector would be a bad thing. I found the keyboard compatibility here: http://www.welovemacs.com/9223109.html

[(I agree with Techknight, but As a note - Is the 5300 keyboard fully compatible with the 3400c?  (just as a warning - i don't think i'd personally leave it in there permanently - …

you will need to replace the keyboard connector itself, as its likely corroded and not making contact. 

I got a new PowerBook 3400c/200 (my second) - the Kanga must wait some more days, as it has more bugs. So the 3400c was said to have a buggy keyboard, nearly all keys don't wor…

It is detecting the drives. I dont see what the problem is?  the IBM drive may need formatted. Also, you will need to change its SCSI ID back to 0, but that wouldnt stop the drive…

I need your help because the new drive I bought still isn't working. Here is what I get from Apple Personal Diagnostics with the old (above) and the new (below) drives: No name…

Thank you! That's the video part, which is faulty. So I have to look if there is a short circuit.

That's fine.  I was just curious.

"far to the right" Do you mean the left or right picture (upper or lower side of the board)? "size cap" In my experience many forums reduce the size of uploaded pics, so a reduc…

Is there a size cap on uploading photos?  It's not a big deal it's just somewhat awkward to keep downloading. Also, your board's main damage is surprisingly far to the right.  I'v…

OK. Thanks! So let‘s see… BTW: Here's a new version of the Kanga logic board pic with some labeling. Could not edit the old post. http://www.mediafire.com/download/cb2726zofow…

Well... remove the corrosion and see what happens.  If the vias or traces are bad then that poses a bigger problem.  But again - my board did not originally have video, and washing…

Thanks! I'm sure there is something similar. Scrubbing Bubbles for sure is copyrighted and therefore is imported directly from the U.S. That makes the price. But what to do w…

It's the ammonium chloride doing most of the stripping. Got alcohol (methanol) and a benzene also doing their thing. And a Base (probably a Calcium based lye) adding to the strippi…

I'll write the ingredients down - maybe you can find something similar.

Ok, I'm thinking what to do. Hmm...
