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.

News:

Apple has released System 7.5 Update 2.0 for their entire line of Macs. Preliminary testing on beta versions and the Zeus Golden Master reveal no incompatibilities like System 7.5 Update 1.0 with clock chipped Mac or clone computers. Please drop me a line if you stumble across any. Oh, if you are still looking for a copy you might want to try: http://www.sims.berkeley.edu/~jwang/System-753/
Please fill out and submit the Clock Chipping Statistics Survey form if you have clock chipped your machine so we can get a reasonable 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 so we can get a reasonably large data set to work with.
