Apple Macintosh Plus
|Home > Browse Our Collection > Computers > Apple Computers > Apple Macintosh Plus|
The Macintosh Plus computer was the third model in the Macintosh line. It was introduced on 16th January 1986, two years after the original Macintosh and a little more than a year after the Macintosh 512K. It originally sold for $2599 USD. It was discontinued in October 1990.
As an evolutionary improvement over the 512K, it introduced RAM expansion from 1 MB to 4 MB, and the SCSI peripheral bus, among smaller improvements. It originally had the same generally beige-coloured case as the original Macintosh ("Pantone 453"), but in 1987, the case colour was changed to the long-lived, warm gray "Platinum" colour.
Operating system 1.1–2.1, 3.0–6.0.8, 7.0-7.5.5
Our Mac Plus together with the original keyboard and mouse was kindly donated by Bob Sheppard.
