== Amiga OS ==

'''Amiga OS''' is the native [[operating system]] for the [[Amiga]] line of personal computers, originally developed by [[Commodore International]]. First released in 1985 alongside the [[Amiga 1000]], it was renowned for its preemptive multitasking, a graphical user interface (the [[Workbench]]), and advanced multimedia capabilities for its era. The system relies on a combination of a [[Kickstart]] ROM-based firmware and a disk-loaded operating environment, with versions spanning from 1.0 through to 3.1 and later third‑party continuations.

== Features ==

Amiga OS features a cooperative multitasking kernel (later preemptive with the Exec component) that allowed multiple applications to run simultaneously. The graphical user interface, Workbench, presented a desktop metaphor with icons, menus, and windows. The system also included the [[AmigaDOS]] command‑line interface, which provided file‑system support and scripting. A notable feature was the ability to use [[ARexx]] (a REXX‑like scripting language) for inter‑application control. The operating system integrated tightly with the custom [[Amiga chipset]] (e.g., [[OCS]], [[ECS]], [[AGA]]) to deliver smooth animation, multiple screen resolutions, and four‑channel stereo sound without additional hardware.

== History ==

Development of what became Amiga OS began in the early 1980s under the codename “Lorraine”. The original design team, including [[Carl Sassenrath]] and [[RJ Mical]], created the multitasking kernel and the user interface. Version 1.0 shipped in 1985, followed by incremental updates (1.1, 1.2, 1.3) that improved stability and added features like the [[Amiga Basic]] interpreter.

After Commodore’s bankruptcy in 1994, rights to Amiga OS passed to [[Escom]] and later to [[Gateway 2000]], which formed [[Amiga Inc.]] in 1997. Version 3.5 and 3.9 were released by [[Haage & Partner]] for [[AmigaOne]] systems. In the early 2000s, a new branch called [[AmigaOS 4]] was developed for PowerPC‑based hardware, introducing a new memory protection model and updated drivers. Later development continued under [[Hyperion Entertainment]], who released AmigaOS 4.1 for several platforms.
