The Computer History Association of California is a charitable, nonprofit corporation established in 1993 to serve six major purposes:
* To study, preserve, protect and popularize the history of electronic computing in the State of California.
* To publish a quarterly journal called the Analytical Engine, devoted to the history which CHAC is mandated to preserve.
* To collect and archive hardware, software and documents significant to that history.
* To participate in an informal network of institutions specializing in computer history, in California and elsewhere.
* To correspond electronically, through the USENET newsgroup alt.folklore.computers, with computer historians worldwide.
* To plan strategically for the establishment of a major, comprehensive, public museum of computing, probably in the Silicon Valley area, by the turn of the century.
