Upon seeing the GUI, Jobs instinctively grasped the potential of this new way of interacting with a computer and didn’t understand why Xerox wasn’t marketing this technology to the public. In 1979, a delegation from Apple Computer, led by Steve Jobs, visited PARC and received a demonstration of Smalltalk on the Alto. Commands, including window resizing, were executed by right-clicking the mouse and selecting from a popup menu. Note the lack of icons, buttons, or an ever-present menu bar. Overlapping windows were a key new feature of Smalltalk, which was a development environment. Shown is a demo given by Dan Ingalls to Steve Jobs at PARC in 1979.

From DOS to GUIīefore the 1970s and even into the early 1990s, a majority of personal computer users interacted with their machines via command-line interfaces, text-based operating systems such as CP/M and MS/DOS in which users had to type arcane commands to control their computers. Without the Lisa, there would have been no Macintosh-at least in the form we have it today-and perhaps there would have been no Microsoft Windows either. What is the Apple Lisa computer, and why was its release on January 19, 1983, an important date in computer history? Apple’s Macintosh line of computers today, known for bringing mouse-driven graphical user interfaces (GUIs) to the masses and transforming the way we use our computers, owes its existence to its immediate predecessor at Apple, the Lisa. ![]() In celebration of this milestone, CHM has received permission from Apple to release the source code to the Lisa software, including its system and applications software. ![]() ![]() Happy 40th Birthday to Lisa! The Apple Lisa computer, that is.
