I've actually taken on another project. I got some direct heat BGA stencils, and a 7447B chip from a dead iBook G4. The target machine is a 2003 eMac, and I had installed the giga designs firmware patch on it. I had swapped the 7445 for the 7447B that I reballed with 0.76mm 63/37 solder balls...

I actually had no idea about this. Very interesting.

I see... I was thinking of a more permanent solution for the sake of convenience though. How would I be able to apply this script?

yes. of course i put fresh thermal paste. i wonder if this is firmware related?

Nice... now we wait :)

Woah, that's insane stuff! Nice work!!!!

I'm actually quite glad to hear the manual drives will work fine in almost all auto macs, those drives are getting harder to find in working condition. But yes... there are definitely some caveats. I personally like the feel and sound of the auto drives, brings me back to when I got my first 68k...

From what it looks like the MDD speakers are 2 inches in diameter... so it might not be too difficult to find a replacement. Then again I'm not entirely sure on this...

Hello. I am looking for someone willing to dump the ROM of their OS 9 compatible 2003 model eMac. Yes, I know you can use the unsupported G4s image, but startup disk won't pick up the OS 9 system folder on OS X if you have one of these eMacs with the newer firmware. And there are ways to go...

Someone I knew a while back actually tried that same thing, and I believe it worked. Both chips are pin compatible.

I might actually have spotted a difference between the two boards but I don't really have access to a spare board anymore... I do like the idea of getting the FSB clocked to 167MHz though, as the 2005 iBooks only run at 133MHz for the 12" board and 142MHz for the 14".

1. Yes. However I didn't use the best caps... which could partly be my issue. I plan to buy fresh new ones from Digikey soon. 2. 10.5.8 6. Yes, and installing my Ti4600 actually got me further, but not to a point where the computer would work. 7. It should, many people have had success with...

Hello, recently I bought a G4 MDD tower and have switched out some capacitors in the PSU for new ones, but then I started having an issue where the system crashes every time I try to start it, and sometimes it will chime but won't boot completely (so it chimes, no video, no USB power). And...

Yes, it would be a good idea to test other components before jumping to the recap, my bad. Should've mentioned that. Wouldn't be a bad idea though considering the age of the machine.

So uh, I did get my reball jig in but it's simply not fit for actualy using it... so I bought direct heat stencils which will hopefully make this easier. How big of solder balls can you use on the PowerPC chips? My best guess is 0.76mm but I'm not entirely sure.

There could be a possibility that the capacitors are starting to go bad. I used to have a 7300 several years ago and decided to dishwash the board which got it working again, but when I tried to power it on months later the issue came back. Parted out the machine anyway considering it was not in...

Already tried that, did not fix anything.
