Macintosh II Explained

On March 2, 1987, Apple introduced the Macintosh II, a personal computer that marked a significant step forward in the Macintosh series. The Macintosh II was designed, manufactured, and sold by Apple from 1987 to 1990 and was considered a powerful and versatile computer at the time.

The Macintosh II was powered by a 16 MHz Motorola 68020 processor and featured a Motorola 68881 FPU coprocessor, providing users with a significant boost in performance. Additionally, the Macintosh II came with 1 MB or 4 MB of RAM, 40 MB or 80 MB hard drive, and two 800 KB Floppy drives. There was also an option for a Macintosh II video card for users who needed more advanced graphics capabilities.

At its launch, the Macintosh II had a starting price of $5,498, which was considered quite expensive at the time. However, the Macintosh II was well-received by users and was considered a solid investment for professionals and businesses.

Unfortunately, on January 15, 1990, Apple discontinued the Macintosh II. Today, the Macintosh II is 37 years old and is considered a classic piece of technology from the 80s. While it may not be as powerful as today’s computers, the Macintosh II was a significant step forward in the development of the Macintosh II series and helped pave the way for future innovations.
