The Amiga Portal

The 1987 Amiga 500 was the best-selling model.
Shortcut

Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. These systems include the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS.

The Amiga 1000 was released in July 1985, but production problems kept it from becoming widely available until early 1986, though a "few" were sold before Christmas 1985. The best-selling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The Amiga 3000 was introduced in 1990, followed by the Amiga 500 Plus, and Amiga 600 in March 1992. Finally, the Amiga 1200 and Amiga 4000 were released in late 1992. Estimates of Amiga sales figures vary, with several older sources presenting values between 4.85 (purely Commodore Amiga sales) and 5.29 million (including Escom sales).

While early advertisements cast the computer as an all-purpose business machine, especially when outfitted with the Sidecar IBM PC compatibility add-on, the Amiga was most commercially successful as a home computer, with a wide range of games and creative software. It also found a niche in video production with the Video Toaster hardware and software, and Amiga's audio hardware made it a popular platform for music tracker software. The processor and memory capacity enabled 3D rendering packages, including LightWave 3D, Imagine, and Traces, a predecessor to Blender.

Poor marketing and the failure of later models to repeat the technological advances of the first systems resulted in Commodore quickly losing market share to the rapidly dropping prices of IBM PC compatibles (which gained 256 color graphics in 1987), as well as the fourth generation of video game consoles. Commodore ultimately went bankrupt in April 1994 after a version of the Amiga packaged as a game console, the Amiga CD32, failed in the marketplace. Escom of Germany, who acquired Commodore properties, continued developing the Amiga line for just under two more years until itself went bankrupt. Since the demise of Commodore and Escom, various groups have marketed successors to the original Amiga line, including Eyetech, ACube Systems Srl and A-EON Technology who have produced AmigaOne computers since the 2000s. AmigaOS has influenced replacements, clones, and compatible systems such as MorphOS and AROS. Currently Belgian company Hyperion Entertainment maintains and develops AmigaOS 4, which is an official and direct descendant of AmigaOS 3.1 – the last system made by Commodore for the original Amiga computers.

AmigaDOS is the disk operating system of the AmigaOS, which includes file systems, file and directory manipulation, the command-line interface, and file redirection.

In AmigaOS 1.x, AmigaDOS was based on a TRIPOS port by MetaComCo, written in BCPL. BCPL does not use native pointers, so the more advanced functionality of the operating system was difficult to use and error-prone. The third-party AmigaDOS Resource Project (ARP, formerly the AmigaDOS Replacement Project), a project begun by Amiga developer Charlie Heath, replaced many of the BCPL utilities with smaller, more sophisticated equivalents written in C and assembler, and provided a wrapper library, arp.library. This eliminated the interfacing problems in applications by automatically performing conversions from native pointers (such as those used by C or assembler) to BCPL equivalents and vice versa for all AmigaDOS functions.

Things to do

  • Create articles: There are many articles that have yet to be started... Pick your favorite and start researching!
  • Find photos for articles: Many Amiga–related articles would be substantially better with the addition of photographs.
  • Expand articles: There are many Amiga stubs which could use extensive updates and development.
  • Find sources: Many poorly sourced articles could use better citations.
  • Wikify: Add {{Portal|Amiga}} to the See also sections of Amiga-related articles.
