Al Kossow, a software curator in The Computer History Museum in California has recently recovered the source code for both, Lisa apps and Lisa operating system by Apple. Currently, Apple is reviewing the source code and once done, the museum is planning to release the code to public for free. Lisa was released in 1983 and was one of the first ever personal computers to come equipt with a graphical user interface and a mouse-supported machine, however it sold only 10,000 units. Regardless of being a flop, the OS holds a great significance in Apple History. Allegedly, it has been stated that this is why Steve Jobs left Apple and this also resulted in a huge drift between him and Microsoft’s Bill Gates. Post OS Lisa’s failure, Steve founded NeXT Computer that was eventually attained by Apple, thereby bringing him back to the Company.
