The Apple II uses a 14.31818MHz crystal (4x color burst) which gives it the ability to generate pseudo-color video on a TV. Click to expand... And so did the original IBM PC, i…

Everything in a Plus runs off a single crystal which was chosen for compatibility with the SCC chip and standard baud rates. If you change the crystal, the Mac may beep and start, …

15.6+- khz is the time it takes to produce a single line on a NTSC tv, so the apple screen is probably really running at or near ntsc tv specs Also it was very common in the 80's t…

What was the reason behind the odd clock speed? Click to expand... It divides evenly (ie by integer) to generate baud rates. But I imagine the pixel clock was an important reas…

15.6+- khz is the time it takes to produce a single line on a NTSC tv, so the apple screen is probably really running at or near ntsc tv specs Also it was very common in the 80's …

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. Click to expand... Ser…

Well, the thing went BANG, and my house RCD tripped (at least it tested that...), a nice smell of burning electrics coming from the power supply followed... Click to expand... …

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…

Too much paste is worse then none at all, even a little that gets stuck on the cache leads will short out a chip. Click to expand... yea if your using lead paste, ive never see…

Nice. Are you planning to resurrect it or use it for some mod?

Well, the thing went BANG, and my house RCD tripped (at least it tested that...), a nice smell of burning electrics coming from the power supply followed... This thing is toast, b…

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 …

Very nice. A free Mac is the best kind.

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.

I got a free eMac a few months back with a dead HD. Put new one in, wouldn't boot. ended up giving up after my 2nd attempt of taking it apart.

Yeah, I did an optical drive upgrade on mine; then two weeks later had the hard drive die; then a month later, when I got a MacBook Pro, decided to put the recently-installed optic…

I used to work on eMacs all the time. The only frustrating step was the pigtail wire that runs from the power button to the logic board. They made the wire so short and there is …

AH! It SUCKS to do an eMac Upgrade. There is no shield over that scary huge CRT. Erhh. It took me hours To complete a DVD Drive upgrade on mine and it doesn't work correctly . iB…

iBooks are a nightmare too. I'm glad they've made it easier in the MacBooks. Click to expand... Yeah, All iBooks were terrible to work on, clamshell included.

System 7.6.1. is exactly what I am booting, and exactly as shown in your video. Very interesting theory. (I am yet order a new battery, I shall find out in a few weeks)
