Macintosh 512Ke Datasheet

On April 14th, 1986, Apple introduced the Macintosh 512Ke, a personal computer that would become a part of the Macintosh series. At a starting price of $1,999, the Macintosh 512Ke promised to deliver powerful performance and a sleek design.

The Macintosh 512Ke featured an 8 MHz Motorola 68000 processor, a 9-inch monochrome display, 512 KB of RAM, and an 800 KB floppy disk drive. It also came with a dedicated operating system, Macintosh System Software, which was designed to make the computer easy to use.

However, despite its impressive specs and user-friendly design, the Macintosh 512Ke was only manufactured and sold by Apple for a year, from 1986 to 1987. On September 1st, 1987, the computer was discontinued, making it 38 years old today.

While the Macintosh 512Ke may be a piece of tech history, it was a significant step forward for Apple and played a major role in the company’s journey to becoming the technology giant it is today.
