I can tell you that it very seldom works on a Wallstreet....
Resetting the battery can be done in Open Firmware, I gather, on a Pismo. Mind you, it hasn't worked for my Pismo's de…

What was the reason behind the odd clock speed?

It divides evenly (ie by integer) to generate baud rates. But I imagine the pixel clock was an important reas…

Everything derives from the same clock. The frequency from the oscillator is divided in half for the processor and further for other IC's. The full clock speed is fed to the video …
If I were to swap out the oscillator, would it potentially damage the Mac? I doubt the .1664 MHz jump would hurt anything, but I want to make sure first.

I am working on a project with my Plus. The analog board is dead and while I do plan to fix it, I want to play around with a microcontroller. Anyway, One thing I'll need the microc…

Depends what condition it's in when it arrives. This will be my third CC. I would like to keep one stock, or stock-ish (ie a LC550/CCII motherboard swap, at most), and reserve th…
Out of curiousity... have any of you ever used BatteryReset 2.0 on a Lombard? If so, were you successful at fixing a battery?
I've got a Pismo and a battery that refuses to take a…

Too much paste is worse then none at all, even a little that gets stuck on the cache leads will short out a chip.

Report back on how your XPostFacto install of 10.2 goes! I've been really interested in getting a Kanga to turn into an OS X machine, but haven't known anything about how easy it w…
Hey, that's awesome of you to cut your friend a deal with the eMac! Have them max out the RAM and install Leopard and they've got a great machine on their hands there... same goes …
Sometimes I wonder if it would be plausible to operate a business that did just this and readying similar computers for use by children. I think that my 8-33mhz Macs, which aren't…
The goal is to fix up and donate to people with disabilities who are in need of a computer. The iMac is ready, a G3 Tower is almost ready, and we are busy working on the G4...just…

Nice!
If you have some time on your hands and want to have some fun, try to put Windows 7 on the Pentium 1 (see here). I just put Windows 7 RC on my Pentium 2 today.
A friend of my moms was looking to upgrade her mac. She went from a 933mhz w/ 256mb of ram and a big ol clunky crt to my dual 1ghz g4, 1.5gigs of ram and the 17" adc monitor. I mad…

I was very lucky, but it goes to show how proprietary RAM modules - must have some "play" in them to be mass produced for slightly different computers. So that's another unique th…
