Apple Lisa is a desktop computer developed by Apple, released in1983. It was one of the first personal computers to offer a graphical user interface (GUI) in a machine aimed at individual business users. The announcement was made by Al Kossow, a Software Curator at the Computer History Museum. Kossow says that source code for both the operating system and applications has been recovered. Once that code is finished being reviewed by Apple, the Computer History Museum will make the code available sometime in 2018. 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
