Tim, Almost all computers back then clocked off of a color burst. Apple 2 for example. Why? Those crystals were super cheap compared to others.

- derleth 15y ago> The IBM wasn't. IBM sold Real Computers to Real Businesses and Real People. That costs money, if only to look good to the CEO who doesn't look at cars that go for less than $300k. Money means quality, right?
- yuhong 15y agoEven most of today's computers ultimately generate their clock off the color burst, though with more complex circuitry.
- duskwuff 15y agoWait, what? The "color burst" is only relevant to analog television signals. It hasn't been used in computers since we switched away from TV monitors in the late 1980s. It's definitely not present in today's computers outside a few video-out circuits (not even VGA, only composite / S-Video output).
