I could be wrong but it doesn't look like the logic board capacitors have been replaced. There also appears to be some corrosion around C12,C13, D6, etc.

Thanks everyone! We're all set and the mac works! Now just need to rebuild the floppy drive.

I have a Mac Plus in my collection that was originally sold in Europe. Thus, it has a 240v compatible PSU. I'm in the US, and here the standard voltage is 120v. I bought this converter on Amazon, as I wanted to 1) try out the computer but 2) keep the internals original...

If you have a g3 beige, I have a 4mb card available.

For what it's worth, can confirm rev A and B are interchangeable. If rev C is the same voltage and amps, you could make your own using an old iBook power adapter as long as you can find a suitable female plug end. I did this for a few months while waiting to find an original adapter for sale at...

I hope you are able to get to the bottom of this with your current board, but given that you have all of the other upgrades already, you could always source a replacement Rev 2 board pretty inexpensively!

My PB100 seems to have suffered some major screen damage over the past few years. When I got the pb in 2019, it was completely fine. Then last year I noticed a small discolored spot. And this year it has basically taken over most of the screen. I assume it's the typical vinegar syndrome and the...

I have a spare 7500 logic board that is working if you are interested/need it. Would only ask what I paid for it+ shipping. Feel free to DM me.

What's the approximate battery runtime on one of these post refurbishment? Just curious :)

First off, thanks to @jmacz for the repair work on this board. It's in WAY better physical and operational condition than when I first got it. After a busy week at work I finally had a chance to spend some more time testing this board. From a cold start (ie no power for over a couple hours)...

You can use any PSU from the other Duo machines, PB 1400, pb 3400, Kanga, G3 Wallstreet, Lombard, or Pismo. They are all compatible.

Yes, standard barrel jacks, typically 5V 1.0-2.0AMP.

Congratulations, enjoy! Looks like you got a pretty complete set!

Glad someone here got this! I actually asked the seller if they would ship to the USA a few days ago but they said collection only.

Hi All, I recently bought a Quadra 950 from someone on these forums. The computer was packed by UPS in a good box with plenty of bubble wrap and arrived without any external damage.  However, the computer just doesn't successfully power up. The seller says it worked perfectly before...
