So..... It could work on a Macintosh XL

You can't use it on any other computer other than a Lisa 2/10.  You could power it up but be prepared for the sound of  jet engine taking off.  Other than seeing if it spins up, th…

"Just a case and monitor" - no logic board then? It's just an empty case? From what I understand, the Wiget is a parallel hard drive, so it's not usable on a Mac.  You might want…

Is this a power board problem? Because if so I'd probably like to try and get my money back on the replacement board.

Personally, I like the look and feel of the 1400c. But i also like the sound of the 3400c.  But I also have more Duos than I know what to do with. All color.  If I were faced in …

If your 3400 works, for the love of all things holy, check the PRAM battery and if it's old get it out of there...

Dump the 1400c IMO. That's the easiest one to pick back up if you ever wanted to. You've got the 3400c for the speed demon, the other one can be less practical, and I'd keep that D…

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 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 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…
