Macintosh XL Datasheet

On January 1st, 1985, Apple introduced the Macintosh XL, a powerful personal computer that was part of the Macintosh series. At a starting price of $9,995, the Macintosh XL was geared toward professionals and power users looking for a high-performance machine.

The Macintosh XL featured a 5 MHz Motorola 68000 processor, which was considered fast at the time. It also came with a 12″ monochrome display, 512 KB of RAM, 10 MB of hard drive storage, and a 400 KB floppy disk drive. These specs were impressive for the time and made the Macintosh XL a formidable machine for its day.

However, despite its impressive specs, the Macintosh XL was only available for a little over a year. On August 1st, 1986, Apple discontinued the Macintosh XL, making it a short-lived but notable addition to the Macintosh lineup. Today, 39 years after its discontinuation, the Macintosh XL remains a piece of Apple’s history and a reminder of the company’s early efforts to push the boundaries of personal computing.
