[[Category:Operating Systems]] '''AmigaOS''' is the native [[operating system]] of the [[wp:Amiga|Amiga]] personal computer, a series of workstations originally marketed by [[Commodore]] from 1985 through 1994, and later by other companies. For a brief history of AmigaOS and the Amiga in general, see [[wp:History of the Amiga|Wikipedia's Amiga history page]].

AmigaOS is notable as being an early GUI operating system, following in the footsteps of systems such as [[Mac OS]] and [[wp:Graphical Environment Manager|GEM]] (although GEM was only considered part of the OS on Atari computers -- see [[wp:Atari TOS|Wikipedia's Atari TOS page]] for more on that topic). Unlike Mac OS, and like most other GUI systems, AmigaOS also included a command line interface.

Like the Macintosh, part of the operating system is contained in the [[wp:Bootstrapping (computing)|boot ROM]], called '''[[wp:Kickstart (Amiga)|Kickstart]]'''. Compared to the Mac, however, significantly more of the OS was contained in the Kickstart.

The command line portion of the OS, implemented by Kickstart, is called '''[[wp:AmigaDOS|AmigaDOS]]'''. While AmigaDOS is not to be confused with [[DOS|PC-style DOS]], it does share some similarities with DOS and other text-mode systems.

The actual GUI is called '''[[wp:Workbench (AmigaOS)|Workbench]]''', and as the name suggests, instead of the now-common GUI metaphor of a desktop (with files and folders), the screen uses the metaphor of a workbench, with tools, gadgets, drawers, etc. (Originally, "Workbench" was the name of the entire OS; version 3.1 was the first version to be called "AmigaOS".)

A modern operating system that seeks to replicate AmigaOS is '''AROS''' (''AROS Research Operating System'', formerly ''Amiga Research Operating System''). AROS seeks to be "compatible with AmigaOS at the API level", meaning that programs written for AmigaOS ''should'' work under AROS by just recompiling.

Another OS that is mostly compatible with AmigaOS is [[wp:MorphOS|MorphOS]]. Unlike AROS, MorphOS is mostly binary-compatible with AmigaOS when run on actual Amigas (meaning that many Amiga programs will run under MorphOS without change).
