Apple’s Legendary Lisa OS Source Code to be released for free in 2018

The Apple’s Legendary first graphical user interface operating system has announced by the Computer History Museum (CHM) to be released publically in 2018. It was initially released along with one of the first Apple’s personal desktop in 1983 with a support for mouse.


Just wanted to let everyone know the sources to the OS and applications were recovered, I converted them to Unix end of line conventions and spaces for Pascal tabs after recovering the files using Disk Image Chef, and they are with Apple for review“, said Al Kossow, a software curator at the museum.


After that’s done, the code that is cleared for release by Apple will be made available in 2018. The only thing I saw that probably won’t be able to be released is the American Heritage dictionary for the spell checker in LisaWrite.”


The Lisa source code is made open source this year after being reviewed by the tech giant Apple.
