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.

Its a good thing you have a large collection, cause you seem to be the bringer of death ... can you get to the main board of the mac, if so sniff around up close (like practicall…

PMed ya.

It's not too, too rare, actually. My Macintosh LC 475 also has the ROM SIMM socket (along with a red PRAM reset button) too.

I'm still kicking myself I didn't bid for the CAMMjet I sold for work last year. /ouch /ouch /ouch Click to expand... Ouch! But if you wanna REALLY feel bad, just ask me how mu…

I"m just curious...what kind of floppy drive does it have? Does it have the older auto-inject floppy drive, or the newer manual inject floppy drive? Just curious, because I know th…

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…

The main processor(s) and MC68882 may operate at differant clock speeds. Click to expand... Ha!

No it needs to match the CPU's clock speed, so it should be a 25 not 16 like that one is. Also don't expect a big performance boost from it.

so something like http://cgi.ebay.com/Motorola-MC68882-68882-co-processor-FPU-cpu-MC68882FN16_W0QQitemZ220347416031QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item334dbabddf&amp…
