On January 16, 1986, Apple introduced the Macintosh Plus, a personal computer that would become a staple of the Macintosh series for the next four years. As a flagship product of the company, the Macintosh Plus was designed, manufactured, and sold by Apple, and it quickly became a popular choice among consumers.
The Macintosh Plus was a powerful computer for its time, boasting an 8 MHz Motorola 68000 processor, a 9-inch monochrome display, and 1 MB of RAM. It also came with an 800 KB floppy disk drive and a dedicated operating system, Macintosh System Software. With its cutting-edge technology and sleek design, the Macintosh Plus was a hit with consumers.
However, all good things must come to an end, and on October 15, 1990, Apple decided to discontinue the Macintosh Plus. Despite its relatively short lifespan, the Macintosh Plus remains a beloved piece of technology, remembered for its contributions to the Macintosh series and its impact on the personal computer market.
Today, 37 years after its introduction, the Macintosh Plus remains a beloved piece of technology history. Its design, features, and capabilities are still impressive, even by today’s standards. It’s a testament to the innovation and creativity of the team at Apple, and it’s a reminder of how far personal computers have come in the last 37 years.
