Status of Lisa 7/7 source release
I just came across this post on the Lisa operating system group.
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. 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. 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
It sounds like the Lisa operating system will be available for download from the Computer History Museum, details should be on their blog in due course.
Lisa was a desktop computer released by Apple in 1983, although technically ahead of it's time it was too expensive and was a commercial failure, however it is regarded as a pivotal element in personal computing.
Full details on the Lisa are on the wikipedia page.
