^^ Rev 1 or 2 The best way to make sure you're getting a Rev. 2 motherboard is the "402" marking on the CMD646 IDE controller chip Click to expand... Franklinstein's rig…

how do i check what revision this is?

Do you have one of the Rev. 1 B&W? Those are reported to have many problems, though most pertain to the UDMA implementation on the primary IDE channel. My Rev. 1 B&…

With my Beige or B&W before installing CPU Director, they ran at a default speed of about 500mhz (I'm not at home so I can't check the exact number) no matter what the jump…

it is a powerforce that you adjust the speed using cpu director. the jumper settings arent supposed to matter. This leads me to think that it is an open firmware problem. I tried…

Is it one of the cards with a dial for speeds rather than a jumper block? If you search for powerforce here you will find a relevant thread.

I have a powerlogix powerforce g3 and my computer wont boot with it installed. It still boots with the orignal processor. The powerlogix was previously installed into a beige g3 …

well, when a mummy and a daddy love each other very much.......

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!…

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…
