Twentieth Anniversary stuff

As some of you may have noticed, the Macintosh recently became twenty. Thus, it is only natural that articles on the history of the Mac have begun popping up all over the web. One of the more interesting pieces is a History of Apple's Operating Systems, which once more shows that nothing comes out of a void. Find it at Kernelthread:

If you want some more anecdotal information, let me remind you of Andy Hertzfeld's wonderful site:

http://www.folklore.org

which covers the development of the original MacOS in much more detail.
