Welcome to the Clock Chipping Home Page

To ease access to some of the most up to date information on crystal oscillator swapping/acceleration on Apple Macintosh (and clone) computers I've started this Clock Chipping Home Page. Please send me any information you think should be added.

Please fill out and submit the Clock Chipping Statistics Survey form if you have clock chipped your machine so we can maintain a large set of statistics for the Clock Chipping Statistics page. If you are just visiting for the first time, please come back later if you clock chip your machine.
