#12 AmigaOS: True Multitasking and GUI in 16 Bits (1985–1996)
1. AmigaOS – A System from the Future Launched with the Amiga 1000 in 1985, Workbench 1.0 (later known as AmigaOS) introduced a complete multitasking desktop environment: Paired with a powerful Motorola 68000 (7.14 MHz) CPU and custom graphics/audio chips (Agnus, Denise, Paula), AmigaOS squeezed every drop of performance from the machine.

Workbench – Windows, Icons, and Real Usability Workbench served as the graphical desktop and file manager: By Workbench 1.3 (1988), the desktop supported icons for devices, games, and applications. The 2.x versions introduced 3D icons, better memory management, and dynamic libraries. Workbench 1.3 – Amiga 500, Author: Bill Bertram – Praca własna, CC BY-SA 2.5 3. True Multitasking and Dynamic Libraries AmigaOS supported full multitasking — each application ran as an independent process, with the OS precisely allocating CPU time. Most OS components were modular libraries loaded dynamically — making the system lightweight and flexible. 4. Software Revolution Powered by AmigaOS AmigaOS enabled software that changed creative computing forever: All of this ran in 1MB RAM, often without a hard drive. Amiga wasn’t just a computer — it was a multimedia station. Deluxe Paint III, Grabbed with E-UAE., Fair use 5.
