Last week, I wrote about Robert Taylor and Charles Thacker, whose work at Xerox PARC inspired such Apple innovations as the graphic-user interface (GUI) and the mouse. Soon, we'll get to see under the hood of how Apple introduced those technologies with the Apple Lisa.
Just as the Computer History Museum did five years ago when it released the source code for Apple DOS, the CHM will now be distributing the source code for the Apple Lisa's operating system. Museum curator Al Kossow made the announcement on Google Groups, writing, "the sources to the OS and applications were recovered… and they are with Apple for review. After that's done, CHM will do an @CHM blog post about the historical significance of the software and the code that is cleared for release by Apple will be made available in 2018."
I'm curious where the source code was "recovered" from. Did the CHM collaborate with Apple to retrieve the code from an archaic floppy disk, much as Tony Diaz and Jason Scott helped Jordan Mechner recover the Prince of Persia source code? Or did some third party, perhaps a former Apple employee, bequeath the code to the CHM?
Regardless of the source, the importance of this release cannot be understated. Rhett Jones at Gizmodo reported, "Lisa was a cutting-edge machine and one of the first to offer consumers a GUI, mouse, and file system, but it was prohibitively expensive and didn’t catch on." To see the origin of these features is to look back at the ancestors of computing staples that are still with us today.
Further, such releases are extremely rare, as Apple is known to be possessive of their intellectual property. In this case Apple has little incentive to make such a release, whether or not there is historical value or modern applications for the Lisa operating system.
Whatever the origin or motivation of both this release and that of Apple DOS before it, the precedents continue to be set, with many implications for the Apple II community. Who knows what other classic software we'll see released from Apple Inc. next?
