Pending my giving away of a 165c, I have three PowerBook's left, and I have to get rid of at least one system for space reasons. PowerBook 3400c/200 with CD-ROM and Floppy module…

I took some voltage measurements, though not very systematically.  On the logic board, I measured between ~1 and 3.5 volts (and nothing in places).  On the power board, I got a ran…

OK well that is interesting. Would still really appreciate your post... I was wrong: my 5300c powers on without PRAM battery with the new power boats... which may not speak to w…

Batteries made no difference either way in my cases.

And let me also ask this: my 5300c had a dead PRAM battery. It usually starts fine. Initially, I thought I had noticed that it would not start at all without the dead battery c…

I'd be really appreciative if you could send me a link to the topic. Until I'm sure a power board is working correctly, I'm not sure how much else I can do/diagnose.

The whining of the power board I talked about on the other recent 3400 thread. The caps are bad. Replace the 2 caps and that should disappear. The pop and non screen come on has…

I'm sure this isn't totally new, but I'll describe the chain of events specific to this PB. I bought it on eBay untested.  There wasn't that much corrosion on the board.  I remove…

     I'm not sure of the APN although that description sounds right. Mine just says AMP Rev. 2.      And was your comment about your logic boards in response to the photos I poste…

Power board hasn't arrived yet. I also forgot to take before pictures, but this is after the first phase of cleaning. There was corrosion on the board under the PCMIA enclosure …

What do those resistors pertain to? And actually to clarify I didn't mean the capacitors 'blew'. But I think they are bad.

Well without the power board it won't do Anything. At least my 3 would not. Any corrosion below the battery and all I can say is good luck.

I have a 3400c that had some corrosion beneath the PRAM battery.  It wasn't actually that bad, and I've cleaned the board with still unknown results.  Hopefully three capacitors on…

I am having the same exact issues with my apple 3 almost to the T. If you have solved this issue please let me know what you tried. I noticed my power supply is making some weird n…

You never fail to deliver, uniserver. hahaha

this guy looks like he is up to no good!

they could have called one Possessed, just to make it a little more juicy.  I never did trust that Mr Macintosh…  Hummm…….. { "lightbox_close": "Close", "lightbox_nex…

I loved this thread at the first post.

That's why I want the one I'm owed, it's the 17" OS9 compatible model.

These are technically things I acquired in 2014 but I've only gotten a chance to start playing with them recently. First off, picked up an iMac G4 mostly so I could have a fast OS…

usually the main filter cap is always good, just replace the brown leaky ELNA ones. the only problem you may find during the process is a corroded circuit board, just spend more t…
