While Working on my powerBook 150 today, I got it to a almost perfect condition. Put it back together and, a Black screen and a bad smell. On further inspection it seems that I hav…

As in trying to acquire any other skill, practice makes perfect. Grab a junk circuit board, and practice removing its caps. You'll quickly learn how much heat is too much, how long…

I've reflowed every joint on that board (literally, all 2000+ joints), just in case. Still getting a Sad Mac error unfortunately. I'm not having much faith in the future of this lo…

If I can get some documents describing the optimal settings for these, i'll be sure to give them a shot. Apple's service source documents show how to perform the adjustments, and t…

PMed ya again.

Well JRL, TO be honest your offer is very tempting, but I really don't want to spend any monies. And shipping from CA might be hell. If you are willing to pay shipping on your end,…

Just curious, how did you remove the old capacitors? I have just order a set of new capacitors for my Mac SE/30 but I am not confidence in doing the replacement by myself. I worr…

So not interested in my offer?

I'd say you may have torched the logic board.

The Hard Drive, smells, and the IDE connector smells on the MainBoard. The Machine is still outputting video. But just a blank black screen.

I had something very like what you are getting with the bad video. Turns out I had 2 bad video memory chips, which caused thin vertical bars over the video. But unlike mine, you …

Yes I've switched the RAM in both to no avail, and double checked the caps on both. The board with garbled video had more corrosion around the capacitor terminals, but no trace da…

Make sure the caps are placed with the correct polarity and value and are actually soldered on both sides. Was there any damage on the board from leaking caps (green residue from c…

I presume you have adjusted the analogue voltages back to optimal after your repairs? That is a common cause of the sad Mac. Also, remove the programmer's switch if installed. C…

The main processor(s) and MC68882 may operate at differant clock speeds. Click to expand... Ha! Click to expand... So do you reckon Apple provided a different clock source …

Hi, I've been busy the past week restoring my dead SE/30 - I have a spare SE/30 machine for parts as well. Both had the Simasimac at startup, so I took about replacing all of the…

Okay, you've convinced me! Burning the iso image to disk now and won't attempt to install without disconnecting the other HD's on the G4. Hmmm. Wonder if it will work in a 9500/…

Congrats on a job well done! Nice to see another Compact Mac kept out of the landfill.

I'm somewhat loathe to risk the Tiger load currently running the G4. Click to expand... Stand up, step away from the computer and seriously consider what you are doing. If you…

were unable to determine the cause of the "Sad Mac" as it had no hex code listed below it... just garbage print. Click to expand... There are a number of known issues that can …

um... you should burn the iso to a disk. use http://burn-osx.sourceforge.net/Pages/English/home.html

Well, I downloaded Ubuntu from the link provided by macgeek417 (a 4 hour process at 70KB) and put the iso image on an empty HD on the G$ MDD. Upon double clicking the image I get …

Well, Dana's website said that a later version took out the CUDA button, but I'm not so sure myself. FYI, my Macintosh LC 475 also has a auto-eject floppy.

I think most, if not all LC475s have the red CUDA reset button - I have two LC475 boards that have it, but neither of them have the ROM SIMM slot, just the solder pads.
