Apple’s Lisa OS to be released for free as open source in 2018

In 2018 the Computer History Museum will release the Apple Lisa operating system for free, as open source, reports Business Insider.

The Apple Lisa — one of the very first commercial computers with a graphical user interface — was a flop, selling only 100,000 units on a $150 million R&D investment on its release in January 1983. The Lisa, with its 5MB hard drive, sold for $9,995 —and remember, this was almost 35 years ago!

Though it flopped, the Lisa introduced a number of advanced features that would later appear in the Mac. Those features included the inclusion of protected memory, cooperative multitasking, a generally more sophisticated hard disk based operating system, a built-in screensaver, an advanced calculator with a paper tape and RPN, support for up to 2MB of RAM, expansion slots, and a larger higher resolution display.
