Apple Lisa Source Code Release

Available Now!

Before the Macintosh, there was Lisa. Though a commercial failure, the Lisa brought the first modern graphical user interface out of the lab at Xerox PARC in 1983.

Adobe PostScript Source Code Release

Available now!

For digital printing to take off in the early 1980s, a new programming language needed to be developed that could define the words and images on printed pages across different computers and printers. That revolutionary software was Adobe’s PostScript, and it led directly to the PDF format that is everywhere today. Learn more.

Xerox PARC File System Archive Release

March 2023

Researchers at Xerox’s revolutionary Palo Alto Research Center (PARC) stored their project files on a shared server from the 1970s up to 1994. CHM and key volunteers have recovered source code, executables, and documentation files of all kinds from the server’s backup tapes and worked to make this enormous archive accessible to the public for the first time.
