Crystal Speedup History 23.Txt

Mac Crystal Oscillator Speedup History 2.3 April 1994 There has been a great deal of interest expressed over the net about these simple and inexpensive Macintosh modifications that yield 20- 40% speed increases. Over the last year or so I have been doing a fair amount of crystal oscillator swapping/acceleration on Mac's, and gathering information from others. I've made several posts to comp.sys.mac.hardware with the bulk of this info and as new machines come out, and new concerns surface, I will try to add them to this history of the modifications, post them on comp.sys.mac.hardware and make them available for anonymous ftp on sumex-aim.stanford.edu in /info-mac/info/hdwr. Included in this version is some of the news on the PowerMac's and Marlin Prowell's new C650 modification.
