Apple to Open Source Its First Graphical OS From the Lisa

It’s not often a computer that performed so poorly in the marketplace has such historic significance, but the Lisa came at an unusual time. Apple was still riding high on the success of the Apple II series, but more competitors were appearing every quarter. Co-founder Steve Jobs was famously excited by the demos of a GUI he saw at Xerox in the late 1970s, and the Lisa was the first machine to leverage that technology. It even had a mouse! Apple spent upward of $50 million developing the first Lisa, which hit the market with a starting price of $9,995 in 1983. Apple only sold about 100,000 units of the Lisa, but the lessons learned from Lisa led Apple to develop the very successful Macintosh a year later.
