In 2014, the Computer History Museum released the Xerox Alto file server archive, constituting about 15,000 files from the Xerox Alto personal computer including the Alto operating system; BCPL, Mesa, and (portions of the) Smalltalk programming environments; applications such as Bravo, Draw, and the Laurel email client; fonts and printing software (PARC had the first laser printers); and server software (including the IFS file server and the Grapevine distributed mail and name server). I told the story behind that archive here.
Today CHM released the Xerox PARC Interim File System (IFS) archive:
The archive contains nearly 150,000 unique files—around four gigabytes of information—and covers an astonishing landscape: programming languages; graphics; printing and typography; mathematics; networking; databases; file systems; electronic mail; servers; voice; artificial intelligence; hardware design; integrated circuit design tools and simulators; and additions to the Alto archive.
I began working on this project in 2018 under an NDA with PARC: reading the old media prepared years earlier by Al Kossow, updating the conversion software I’d written for the earlier Alto project, and winnowing down a list of 300,000 files to the 150,000 files that I submitted to PARC management for approval. David Brock’s post ends with an Acknowledgments section noting all the people at CHM and PARC who contributed.
