Apple launches the Macintosh 512K

Introduced in September of 1984, the Macintosh 512K Personal Computer was the first update to the original Macintosh 128K. It was virtually identical to the previous model, differing primarily in the amount of built-in memory (RAM), which quadrupled the original's from 128K to 512K. This large increase earned it the nickname Fat Mac.

At launch, the Macintosh 512K sold for $3,195.

In April 1986 the Macintosh 512K was replaced by the 512Ke.
