Macintosh

The Macintosh was created by Apple when they realized loads more companies has jumped on the bandwagon of computers, so they came up with this. The Macintosh ran a very early version of Mac OS X which was originally called Macintosh System 1.0 and went up to version 7. Although this went back a step because it had a black and white monitor but it is (and still is) a very small machine for it's power (well it can actually beat todays computers).
