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 500, also known as the A500, was the first popular version of the Amiga home computer, "redefining the home computer market and making so-called luxury features such as multitasking and colour a standard long before Microsoft or Apple sold these to the masses". It contains the same Motorola 68000 as the Amiga 1000, as well as the same graphics and sound coprocessors, but is in a smaller case similar to that of the Commodore 128.
The Amiga 600, also known as the A600, is a home computer introduced in March 1992. It is the final Amiga model based on the Motorola 68000 and the 1990 Amiga Enhanced Chip Set. A redesign of the Amiga 500 Plus, it adds the option of an internal hard disk drive and a PCMCIA port. Lacking a numeric keypad, the A600 is only slightly larger than an IBM PC keyboard, weighing approximately 6 pounds (2.72kg). It shipped with AmigaOS 2.0, which was considered more user-friendly than earlier versions of the operating system.
The Amiga 3000, or A3000, is a personal computer released by Commodore in June 1990. It is the successor to the Amiga 2000 and its upgraded model Amiga 2500 with more processing speed, improved graphics, and a new revision of the operating system.
The Amiga 2000 (A2000) is a personal computer released by Commodore in March 1987. It was introduced as a "big box" expandable variant of the Amiga 1000 but quickly redesigned to share most of its electronic components with the contemporary Amiga 500 for cost reduction. Expansion capabilities include two 3.5" drive bays and one 5.25" bay that could be used by a 5.25" floppy drive, a hard drive, or CD-ROM once they became available.
Chip RAM is a commonly used term for the integrated RAM used in Commodore's line of Amiga computers. Chip RAM is shared between the central processing unit (CPU) and the Amiga's dedicated chipset. It was also, rather misleadingly, known as "graphics RAM".
Amiga Advanced Graphics Architecture (AGA) is the third-generation Amiga graphic chipset, first used in the Amiga 4000 in 1992. Before release AGA was codenamed Pandora by Commodore International.
Autoconfig is an auto-configuration protocol of Amiga computers which is intended to automatically assign resources to expansion devices without the need for jumper settings. It is analogous to PCI configuration through ACPI.
This is a list of models and clones of Amiga computers.
The Amiga computer can be used to emulate several other computer platforms, including legacy platforms such as the Commodore 64, and its contemporary rivals such as the IBM PC and the Macintosh.
Minimig is an open source re-implementation of an Amiga 500 using a field-programmable gate array (FPGA).
The Commodore A1060 Sidecar is an expansion hardware device developed by Commodore and released in 1986 for the Amiga 1000 computer. It is an IBM Personal Computer XT-clone in an expansion case which connects to the expansion bus on the right side of the Amiga 1000 computer. It sits beside the computer similar to a motorcycle's sidecar.
The Amiga 4000T, also known as A4000T, is a tower version of Commodore's A4000 personal computer. Using the AGA chipset, it was originally released in small quantities in 1994 with a 25 MHz Motorola 68040 CPU, and re-released in greater numbers by Escom in 1995, after Commodore's demise, along with a new variant which featured a 50 MHz Motorola 68060 CPU. Despite the subsequent demise of Escom, production was continued by QuikPak in North America into at least 1998.
Kickstart is the bootstrap firmware of the Amiga computers developed by Commodore International. Its purpose is to initialize the Amiga hardware and core components of AmigaOS and then attempt to boot from a bootable volume, such as a floppy disk. Most Amiga models were shipped with the Kickstart firmware stored on ROM chips.
The Amiga 1200, or A1200, is a personal computer in the Amiga computer family released by Commodore International, aimed at the home computer market. It was launched on October 21, 1992, at a base price of £399 in the United Kingdom and $599 in the United States.
The Power A5000 was a planned Amiga clone computer, announced by German DCE Computer Service GmbH and British Amiga peripherals manufacturer Power Computing Ltd.. It was one of the first Amiga clone computers announced after Gateway purchased the Amiga in 1997.
The AA+ chipset was a planned Amiga-compatible chipset that Commodore International announced in 1992. There were two separate projects: the next generation Advanced Amiga Architecture chipset and the lower cost, more pragmatic AA+ chipset. The former was in development when Commodore declared bankruptcy; the latter existed only on paper. Both were cancelled when Commodore folded.
In addition to the Amiga chipsets, various specially designed chips have been used in Commodore Amiga computers that do not belong to the 'Amiga chipset' in a tight sense.
Retargetable graphics is a device driver API mainly used by third-party graphics hardware to interface with AmigaOS via a set of libraries. The software libraries may include software tools to adjust resolution, screen colors, pointers, and screenmodes. It will use available hardware and will not extend the capabilities in any way.
The DraCo, also known as DraCo Vision in one of its later models, was a non-linear video editing workstation created by MacroSystem Computer GmbH in 1994, based on the Amiga platform.
