In 1970, the well-heeled corporate behemoth Xerox, with a nearly perfect monopoly on the quintessential office technology of photocopying, cut the ribbon on a new and ambitious bet on its future: the Xerox Palo Alto Research Center (PARC). PARC was a large research and development organization, comprised of distinct laboratories. Several concentrated on extending Xerox’s dominance of photocopying, like the General Science and Optical Science Laboratories. Others, specifically the Computer Science and Systems Science Laboratories, were aimed at a new goal. They would develop computer hardware and software that could plausibly form the basis for the “office of the future” some ten to fifteen years hence, giving Xerox a profound head start in this arena. //
Individual Alto users could store and back up their files in several ways. Altos could store information on removable “disk packs” the size of a medium pizza. Through the Ethernet, they could also store information on a series of IFSs, “Interim File Servers.” These were Altos outfitted with larger hard drives, running software that turned them into data stores. The researchers who developed the IFS software never anticipated that their “interim” systems would be used for some fifteen years.
With the IFSs, PARC researchers could store and share copies of their innovations, but the ancient anxiety demanded the question: “But what if something happened to an IFS?!” Here again, Ethernet held a solution. The PARC researchers created a new tape backup system, this time controlled by an Alto. Now, using Ethernet connections, files from the MAXC, the IFSs, and individuals’ Altos could be backed up to 9-track magnetic tapes. //
The nearly one hundred and fifty thousand unique files —around four gigabytes of information—in the archive cover 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.
