A little Googling has turned up V150H button cells as replacements for the V110H cells originally in 2400c backup batteries. The V150Hs appear to be simply higher capacity successo…

What gets rusty in an old Mac or IIgs? RF shielding and power supply cases, surely? The metal chassis doesn't tend to rust unless it is very badly scarred and stored in a damp envi…

If we are talking about rust then use a light oil to clean it off. Oil and an old rag.

Steel wool is just an abrasive. Why not use glasspaper or sandpaper? The residual grit still needs to be washed away, but it is far less conductive than steel wool.

Thanks for the tip!

If you do, take *everything* electronic out, use the steel wool to clean only the components with rust on them while they're removed from the case, and wash them thoroughly before …

As you can see by this pic the inside of this GS has some rust and other corrosion, so my question is: what should I remove it with? Is steel wool the best option? Or is there some…

All three rectangular metal self resetting fuses F1 F2 F3 should measure about +26.5V on both ends, also SMT cap C40 at the + end. You can also inspect T1 T2 T3 to make sure no on…

Have you tried an OS X install with a fully functional internal optical drive? I've had the occasional glitch on my OS 9 sawtooth with firewire that otherwise runs fine under X. …

Have you tried an OS X install with a fully functional internal optical drive? I've had the occasional glitch on my OS 9 sawtooth with firewire that otherwise runs fine under X.

I tried all three ports including the internal. In the OS 9 system profiler, it does not show any devices, just a few bits of gibberish like "g45dv, 7hd5h" for the bus and some oth…

I think that the only G4 which shared the seperate Firewire board with the yosemite was the yikes. As far as I know, all sawtooth mobo's had the firewire fully integrated.

From what I've gleaned from teh intarwebz over the past week looking for potential fixes for my dead PBG4, it seems that FireWire failure was pretty common on at least the early Po…

Did you try the internal one as well?

I've read reports of dead FW ports on xlr8yourmac.com - the fix has been to get a FW PCI card then all is well.

Has FireWire been known to give out on a G4 AGP Graphics? I hooked up my FireWire DVD drive as I always do to install the OS, but on this particular G4 it doesn't work. The drive …

It's back up for now, but it would be nice to figure out the cause. Thank goodness for being able to preserve users and applications, otherwise it would be considerably more painf…

My PowerBook G4 did the whole prohibitory-sign boot failure once or twice immediately before it refused to turn on ever again. Still not sure what died on it.

I'm home now and am in the process of a Archive and install of 10.3. It sucks but at least I won't have to reinstall my software. Strangely enough, I did not have to remove one o…

Probably the best looking G3 AIO I've ever seen! (i'm sorry, but I've always found them to be profoundly ugly, even back when they were new )

Doesn't sound good - cmd+v should be passed to the kernel, which would be the very first thing that gets loaded... if it's not even doing that... Try boot hd: or mac-boot from the …

Yes, before the bong sound.

Are you holding the keys down as soon as you press the power button?

Try booting up in verbose mode (hold down command-v on boot) and see what message it gives you when it crashes. Click to expand... No response. It still does the same thing.
