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…

The most primitive stand alone Apple LCD was the blue & white 15" Studio Display at 1024x768. It is a multi-sync display so it will display 640x480. The earliest LCDs from …

My, that's pretty.

The closest "match" you'll be able to find is likely IBM's first LCD desktop display, the 9507, which was meant to go with their low power PS/2e desktop computer. (Which was basic…

I happened upon this thread and thought I would add my two cents. Hope this is useful and not a "me too" sort of deal. I have a IIci that I made out of two IIcis, and I was think…

Yeah, definately something to look into. For now, I'm just saving the iBook as a rainy day project xx( .

Not sure if anyone else has mentioned this directly, but the early Dual USB iBooks with Rage graphics did not suffer from the GPU problems that the later Radeon models did. In fact…

I don't have access to an external HDD.. (well I do, but its over 128GB..) Click to expand... That wont matter if it is an external HDD - If it is a firewire HDD then it could …

Thanks, I was thinking the HDD. The machine acts virtually normal when booted off the 9.2.1 CD. I don't have access to an external HDD.. (well I do, but its over 128GB..) so I don'…

The machine has the basic 64MB RAM, which would be the chip soldered. Nothing has been added. Would buying a RAM stick help? Click to expand... Adding more RAM at this point is…

Well im not sure what the problem is, I think you should throw it in the garbage tonight.

Thanks for helping me with this, I'd like to get to the bottom. I've reinstalled the OS (9.2) several times, with no avail. Last time I completely reformatted it and preformed a c…
