The 1.x series of Amiga OS defaults to a distinctive blue and orange color scheme, designed to give high contrast on even the worst of television screens (the colors can be changed by the user). Versions 1.1 consists mostly of bug fixes and, like version 1.0, was only distributed for the Amiga 1000, and entire OS came on a single floppy disk. The entire set of Amiga OS consists of three disks: Kickstart, Workbench and ABasic by MetaComCo.
