Seems like it has already done the rounds of forums Just found this when searching the serial number: SG0140FLJ7B http://www.macuser.co.uk/forum/viewtopic.php?t=299402&hi…

Those G4 upgrades are really hard to find. Only the early iMacs with the internal expansion port can be fitted with them. Finding them unused or freed from the confines of the mach…

Which model PBG3? IIRC, they all used different model battery packs for some of the PBG3s. However, if it's a Lombard or Pismo, they both used the same model PRAM battery. I thi…

Fans will do that over time. Dust and dirt accumulates on the vanes of the fan and throw it out of balance which stresses the motor and bearings. Keeping them clean will increase t…

Ok I'll try the steel wool. I tried a pencil eraser but it didn't seem to help. The contacts on one seem to be a bit corroded or damaged so that's probably the issue. Tempest

Couldn't value it at the time so paid the scrap value for the Airport Card, RAM and plastics

That's an unexpected bonus! What was the cost?

just something to try ...scuffing the contacts lightly with some fine grit steel wool, works better than pencil eraser on mismatched "settled in" parts, but its dust is highly cond…

If these SIMMs are all identical, then at least 1 of the 4 is dirty or bad. Check to see if the numbers on the actual chips match from SIMM to SIMM. If they're different at all, …

Bought a Flower Power iMac G3 that turned out to have a G4 upgrade inside. It started out as a Snow G3 400 but over time has had many parts added/swapped out including the casing …

Yes I found it. When I put the 'bad' set of RAM in I get a normal chime but then nothing happens (the OS never loads). When I stick a good set in the other bank I get the chimes …

and the other 4 appear to be bad (the Mac won't boot with them in), but I assume they're also 1MB sticks. Click to expand... If the RAM is bad, the Mac should make a death chim…

What is the voltage supposed to be? I am reading 3.06v and 3.04v.

Well I finally got the IIfx working. Turns out both of my SuperDrives are bad (not sure if they're fixable) but I had a spare working HD so I was able to get it to boot into Syste…

System 7 seemed somehow "tuned" to run really well on the IIci. Click to expand... Yep, it is the first Mac with the new universal ROM that has 32-bit QuickDraw, Gestalt, and m…

I booted your IIfx from an external hard drive without a terminator at all Tempest. I think it depends a little on your drive too. Terminators are tricky and unpredictable as to …

I just vacuumed the psu fan without even opening it and the case fan while I was at it, and the G4 is now quieter than it has ever been!

sounds like the fan, so yea try blowing it out, and worst case you can replace the fan fairly easily

Today, my Mystic G4's power supply started making an out-of-the-ordinary noise instead of the typical. With the unusual noise, the case slightly vibrates as well. I could tell it w…

I love my Ataris, but they have been put away for most of the past year while I have been slowly moving my music setup around. I've got a box of Dr. T's software which is all amazi…

Regarding the dead PMG4: The reason it isn't responding, powering up or waking from sleep is due to the Power Management Unit getting a bit screwed up. To fix the problem, I woul…
