Apple Macintosh Personal Computer, 128K, c.1984, with integral monitor and disk drive, model no. M0001P, s/n F5140X2, together with separate keyboard and mouse

Apple Computer Inc. designed the Apple Macintosh to be as user-friendly as possible. It had a 23cm monochrome monitor screen, 128 kilobytes of RAM, and came with a keyboard and mouse, a novelty for the time.

It was the first personal computer with a graphical user interface (GUI), featuring a 'desktop', windows, and clickable menus rather than a text-based display. Within a year, Microsoft introduced its own GUI operating system, Windows.
