You can now download the source code for Apple's most influential failure

The Apple Lisa was the home computer that introduced a graphical user interface (GUI) to the masses. Without this pivotal step in computing, we might’ve seen a very different desktop emerge. Maybe we wouldn’t have seen a desktop at all. The whole concept of windows, files, folders, and navigating them via a mouse input was something the Lisa brought to bear for average computer users, at a $50 million R&D expense to Apple.

Admittedly, Apple wasn’t the first to integrate a GUI into a functional machine. That was Xerox’s breakthrough to claim, and it first made an appearance as the Xerox Star operating system and accompanying computers. However, it was Apple’s machine that brought this concept to the public eye in a somewhat more affordable machine. Steve Jobs and a delegation of Apple engineers visited Xerox’s PARC R&D campus and famously caught wind of this new-fangled GUI idea that the company was working on, and Jobs decided that was what he wanted for the Lisa project Apple was working on at the time.
