How much is a 128MB stick worth? I have one in a broken machine and it might need to be sold if I can't get a replacement machine to use. Thanks.

I cleared the G4 DA by removing its drives (three of them) to a G4 MDD, where they work properly and without any grizzles or KPs. The one unfortunate response was OS 9.2.2's inabi…

I'm not sure if OS X sort of ear-marks certain kexts during install for potentially faster loading or something. Dunno. If you're using an SDR RAM eMac, then the architectures sho…

Try installing Tiger and then use Migration Assitant to transfer the files. The install still thinks your on the eMac witch can cause problems in the innards of OS X. I usually get…

A while back I was attempting to clean up a newly-bought 'not working' iBook G3/600 in target disk mode from an eMac. It was a successful exercise, but the next night, when Retros…

I'm preparing a G4 as in the title for my wife, who currently uses an eMac/1GHz, so that she can use an ADC Cinema Display HD (23") with it. Erase and install (using a SuperDuper!…

…stabilize the surface with a proprietary liquid (such as Kill-Rust, Neutra Rust, End-Rust) containing chromium salts, phosphoric acid and poly-(vinyl acetate)… Click to expand.…

Copper, brass or bronze, depending on the hardness desired, but most often brass. If the rusted metal is the bright steel (which relies on its polished surface to resist rust) of …

There is indeed something better, and it's designed for the purpose. It looks just like a toothbrush, except the brush bit is made of brass (or copper?) wires. I can't recall whe…

Soldering should work. Those tabs are welded to the cells, but intended for you to solder them at the far end either to each other or into a PC board. The batteries will see the …

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.
