What is the History of xerox alto?

The Xerox Alto, developed at Xerox's Palo Alto Research Center (PARC) in the early 1970s, is considered one of the first personal computers to use a graphical user interface (GUI) and a mouse. Designed primarily for research purposes, it introduced groundbreaking concepts like desktop metaphor, Windows, and icons, which would later influence future operating systems. Despite its innovative features, the Alto was never commercially sold, with only about 2,000 units produced, but it laid the groundwork for later systems like the Apple Macintosh and Microsoft Windows. Its development marked a significant shift in computing, emphasizing user-friendly interfaces over command-line interactions.
