| 3400 board question... |
Posted by: J English Smith on 2009-12-30 12:48:07
Wow! I just heard back from a seller that he's got a 200 mhz board for a PB 3400 for only $20. Can anyone confirm that it's possible to transplant a 200mhz. board into a unit that shipped with 180mhz.? I've got the take apart directions and I should be able to do the work...

I can't see why not - it was never an official upgrade, but all the other parts should be the same.

While you have it apart, why not shoot for 225MHz? That would make it the fastest non-G3/G4 Powerbook ever 🙂

Or better yet, track down a board from a 3400/240, the fastest stock pre-G3 PowerBook ever. 😉
(or just track down a Kanga board)

Ah yes, I forgot about the 240MHz model.

Thanks for everyone's comments. I think I'm ready to pull the switch on this! I will check and see if they have the 240mhz board; but for $20 + ship, the 200 may be the most cost-effective way to go.
I hooked the 3400 to a good H-P monitor with mini-VGA connection and got "no signal" on the monitor. I get a chime and I do hear the hard drive working at startup. I have inspected the built in screen with a LCD flash and I see no active display, IE, it's not just the backlight that's out.
Based on all that, and the fact that the seller said the monitor cable was replaced by a pro repair service about two years ago, I am betting that it is the logic board/VRAM issue and not the display or cable. Holler if anyone thinks that logic is in error.

That's certainly a cheap fix. Be patient with the teardown, and keep track of your screws.
BTW, in case it wasn't clear from LC_Guy's reply above, the "Kanga" G3 Powerbook logic board should be a drop-in replacement as well.

Good advice always, Bunsen, thanks.
I'll post a progress report when the patient is off the table...
