The Macintosh, later rebranded as the Macintosh 128K, is the original Macintosh personal computer from Apple. It is the first successful mass-market all-in-one desktop personal computer with a graphical user interface, built-in screen and mouse. It was pivotal in establishing desktop publishing as a general office function. The motherboard, a 9 in (23 cm) CRT monochrome monitor, and a floppy drive are in a beige case with an integrated carrying handle; it has a keyboard and single-button mouse.
The Macintosh was introduced by a television commercial titled "1984" during Super Bowl XVIII on January 22, 1984, directed by Ridley Scott. Sales were strong at its initial release on January 24, 1984, at US$2,495 (equivalent to $7,600 in 2024), and reached 70,000 units on May 3, 1984. Upon the release of its successor, the Macintosh 512K, it was rebranded as the Macintosh 128K. The computer's model number is M0001.
