Yes, trag's caps are great. I need to get some more from him. I am missing one capacitor in order to complete the replacement on my SE/30. I am also missing one capacitor in order …

Thanks to Trag whose handy capacitor kits make it easy to get into fixing up these boards. If it weren't for him, my portables would still be sitting dead in the closet. :beige: …

I finished capacitor replacement a few nights ago. Here are some pictures.

That's a very good tip. Though it does require constructing an extra long cable between the logic board and analogue board. It also doesn't help identify more than one bad chip at …

I remember a trick that I tried. With the board out of the case, press a memory chip over the chips on the board one at a time Make sure that the pins only touch the correspondin…

Here's a picture that at least highlights, if not proves my point. An original mid-prodcution 128K logicboard with Apple branded RAM chips. Two of them had to be replaced last year…

Just an update, I used the 8.6 (international) G4 disc on a SawTooth, no issues. I did have some problems previously on a drive that had been formatted by a newer Drive Setup (9.2…

you can also use a solder saturated wick to hot mop the area, its a bit less wasteful and abit less time consuming although your going to have to clean up a ton o flux

I finally got my tools in order and took the time to do some work on this smoking hot babe today. First off, I removed all the nasty caps with my new diagonal cutters. Some of the…

Got the Mac OS ROM file, been really busy at work (where the Sawtooth project is underway), so I dropped it into a 1st gen slot-loading iMac DV at home (also a special-case machine…

I still have the 2.5.1 ROM if anyone needs it - just send me a PM.

Desperately in search of Mac OS ROM 2.5.1 to get 8.6 running on a PowerMac G4 SawTooth. I have scoured the abandonware archives and used my status as Apple Certified tech to check…

I have them, and a few more I picked up along the way. No, I haven't uploaded them yet.

Now this is an odd find: On offer is a VINTAGE COLLECTABLE - BRAND NEW Apple PowerBook {x00} Series Video Service Course as part of the Apple Service Training Courses. This b…

Bargain! Click to expand... Of course, that is for *without* the coprocessor.

now at half that price Click to expand... Bargain! [)] ]'>

Yeah, like that's gonna happen. They are like $250-$300 each in bulk according to Freescales' site. Click to expand... Well, they did eventually make a 40Mhz 68LC040, which is …

It's possible of course that the bad part is a cache RAM chip instead of the G4. Click to expand... ARG!!! Why can't I just let it die in peace? It worked for about three days…

Similar experience with my Sawtooth running a 1.2GHz PLX CPU. In my case the DIP switches which set the buss multiplier evidently glitched and it went to 1.6GHz, which is way overc…

I'm glad I did that to the CPU card I got for my MDD then. Damn thing seems to run hot enough as it is.

Regardless of whether a machine appears fine, you should replace the foil between the CPUs and the heat sink the first time you take the heat sink off. Heat sink compound is alway…

I am amazed that it didn't happen sooner! My MDD was regularly +150F, yet it didn't complain for five years. Meanwhile I had a feature creep situation with a project for recasing i…

So the problem was the CPU daughtercard? It seems this is a common issue with overheating. I've experienced it viewtopic.php?f=13&t=13430 And other have too viewtopic.php…

IT'S ALIVE!!! I collected all of my MDD bits together tonight and set about methodically testing. First I tried combinations of RAM sticks - they can't all have gone bad! And unli…
