Why are the images snipped out of the thread? It's a little hard to see what's meant here.

Wow, awesome!  It's strange seeing greyscale VGA on a Compact Mac CRT, that's for sure.

Well, I wound up using this machine as a CRT donor to fix his other machine that had a CRT with some deep gouges in the front glass from being set down screen side down on the ground at the dump where it was found.  That machine is a tray-loader and should be much more reliable in the grand...

I'm going to try heating the board up with a hairdryer, I can see if getting things warm allows it to power on.  If it does, I'll go ahead and replace the caps.  If not, It's likely the flyback and that's unobtainium unfortunately.

Nope, VGA port isn't populated.  The problem is the PSU won't even start up, I don't think it's a logic board issue.

Hi all, I'm looking at a 350MHz iMac for a friend.  It doesn't power on when the button is pressed at all.  I can hear the high voltage come up for a second, and then slowly discharge when the button is pressed.  The Power LED doesn't come on, or even flash.  I don't hear the CRT degauss.  I do...

Yes, if the hard drive shows up on the desktop.  Open the hard drive, and then the System folder, and then Control Panels.  Remove anything related to the screensaver (I would move it, not delete it, just outside the system folder).  Then, do the same thing in extensions.  Then see if it boots.

Did you power it up with the cap backwards?  if not just turn it around.

Not sure why it failed, but those voltages look normal to me, as lead acid is normally higher nominally than the 6 volt label, and charge voltage a bit higher than that.

Is this on your Quadra 650?  If so, it has onboard Ethernet.  You should get an AAUI to RJ45 transciever so you can use Ethernet instead of burning CD coasters.

That card looks super easy to clone.  Hmmm.

What is the number on it?  It may be a diode in a TO-220 case.

TattleTech.  Super useful for hardware related stuff.  Also the SetDate utility, because otherwise you can’t set the correct date and time on anything older than OS 9.

Also, please use sockets for swapping chips like this.  Much less damage to the board if you have to make changes and makes finding bad chips much faster.

Let the dual wielding begin!

This is really awesome.  I'll be looking forward to seeing the first repro SE board booted up! The SE/30 has more custom logic, no?  Is it possible to program another chip with the VLSI code?  Or would some modern replacement need to be made? RE LCDs:  While this is probably the only way to...

I really doubt that they care about these machines at all, much less go after someone recreating the PCBs.  It's been done for the Apple II machines, so I doubt they would start now!  No worries!

You know, if you think about it, the manufacturer put it on for a reason, and there was probably a good one.

Soldering one of these together sounds like a lot of fun!  My SE board works, but I wouldn't mind putting one together to test!

I paid literally 1 USD for my untested (working) 15 inch 1.5 GHz AlPB.  It's not even really dinged up.
