One of my OS 9 machines is a G4 (AGP) with an Giga Designs G4 1,4 GHz upgrade. It worked quite well for about 2 years now, until 10 days ago when it began to hang permanently. The…

I'm going to have to let one of our other forum members take over from here, unless I can dig up more information. Although the symptoms do appear to match that of a Vreg chip faul…

update 2: pressing down on the heatsink did the job. as soon as i let go, the screen went blank. this leaves me with two questions: 1: did i actually press the gpu against the mai…

update: i tried to manually apply pressure (like shimming) to the chip while turning on the machine, but it had no effect: nothing on the screen, but the computer was booting nicel…

i took it apart and did a test. if i press down on the mainboard, where the main display connector is (left of the area between the keyboard and the trackpad) it works well. if i l…

thanks for the detailed reply. i'm not entirely sure what you meant by 'scraping the laminate off', though. i've never had a problem with a gray screen. it always consistently g…

considering tolerances you should be ok

Pin 28 on your Vreg chip has come loose from the logic board. http://www.xlr8yourmac.com/tips/iBookG4_vreg_repair/ibookG4_vreg_repair.html You don't have to scrape the laminate f…

hahaha, thank you. i knew about this, even read the article, but - for some reason - thought only g3 ibooks are affected. well, i guess it's time to open her up again - this tim…

Some people say the iBook G4 has the "video chip coming loose from the PC board" issue. There is also a pin that comes unsoldered on a voltage regulator chip. The latter is fixable…

My poor Plus just had its second Analog Board die, most likely C1, as I have the vertical line down the middle of the screen. As I inspect the previous Analog Board I had in it, C…

The Macintosh IIfx relies on both batteries to start up unfortunately. Mike Richardson (forum member here) sells them for cheap though and ships internationally. Check out his …

Dunno if this requires a new thread. But I've bought a Dayna E/II-T DaynaPort Nubus card. It says no errors. EtherTalk looks to work. I have Mac OS 6.0.8 with MacTCP. But I can't s…

or both, altho CA glue tends to be abit brittle, but i cant think of anything else that would wick its way into the crack as easy

Or you can try filling the crack with cyanoacrylate (aka Krazy Glue/SuperGlue)

ISTR that you shouldn't mix EDO and FPM RAM in one machine: can't recall if that's "no boot" bad, or "escaping magic smoke" bad.

I did get it, and it looks great. Not a lot of yellowing, either. Shipped in an original Power Mac 8100/80 box with styrofoam. Kinda neat to have that, too. The floppy drive bezel …

So did you get the 840AV - hows it look? I'm pretty sure I've a 32MB EDO SIMM in my 840AV - it won't hurt - give it a shot - but ideally you should go for FPM. ECC EDO RAM def…

The traditional way to prevent cracks from going further is to drill a small hole at the end of the crack. Not flash, but will save the plastic from further cracking. JB

Well I got a bunch of memory on craigslist the other day for REALLY cheap. Guaranteed to work or my money back. They're 72pin 60ns SIMMs, but they're EDO, and I wanted to make sure…

Finally got my Lombard back up to 512MB RAM. So nice.... Anyway, I noticed on the bottom of the case that there is a crack from the Apple logo to about 2/3rds of the way to the r…
