{{Main|List of Amiga models and variants}}

The original Amiga models were produced from 1985 to 1996.<ref name="AutoP5-12" /> They are, in order of production: [[Amiga 1000|1000]], [[Amiga 2000|2000]], [[Amiga 500|500]], [[Amiga 1500|1500]], [[Amiga 2500|2500]], [[Amiga 3000|3000]], [[Amiga 3000UX|3000UX]], [[Amiga 3000T|3000T]], [[CDTV]], [[Amiga 500+|500+]], [[Amiga 600|600]], [[Amiga 4000|4000]], [[Amiga 1200|1200]], [[Amiga CD32|CD32]], and [[Amiga 4000T|4000T]]. The PowerPC-based [[AmigaOne]] computers were later marketed beginning in 2002. Several companies and private persons have also released Amiga [[Clone (computing)|clones]] and still do so today.

=== Commodore Amiga ===
[[File:Amiga 1000DP.jpg|thumb|The [[Amiga 1000]] (1985) was the first model released.<ref name="AutoP5-13" />]]

The first Amiga model, the Amiga 1000, was launched in 1985. In 2006, [[PC World]] rated the Amiga 1000 as the seventh greatest PC of all time, stating "Years ahead of its time, the Amiga was the world's first multimedia, multitasking personal computer".<ref name="AutoP5-14" />

Commodore updated the desktop line of Amiga computers with the [[Amiga 2000]] in 1987, the [[Amiga 3000]] in 1990, and the [[Amiga 4000]] in 1992, each offering improved capabilities and expansion options. The best-selling models were the budget models, however, particularly the highly successful [[Amiga 500]] (1987) and the [[Amiga 1200]] (1992). The [[Amiga 500+]] (1991) was the shortest-lived model, replacing the Amiga 500 and lasting only six months until it was phased out and replaced with the [[Amiga 600]] (1992). The A600 was only intended as a temporary gap filler until the A1200 was available for sale. The A600 was actually designed as a portable system, hence the lack of numeric Keypad, and it was originally to be named Amiga 300. Some early A600 models have retained the original A300 logo printed on the mainboard. The Amiga 600 was quickly replaced by the Amiga 1200.<ref name="AutoP5-15" />

The [[CDTV]], launched in 1991, was a [[CD-ROM]]-based game console, Computer and multimedia appliance based on the Amiga A500 with the same v1.3 Kickstart ROM, several years before CD-ROM drives were common. The cost of CDTV media production and the CD-ROM drives at the time discouraged potential buyers and the system never achieved any real success. The CDTV was however one of the first ever CD-ROM-based machines that were mass-produced. A CDTV legacy is the external A570 CD-ROM drive expansion for the A500 computer.

Commodore's last Amiga offering before filing for bankruptcy was the [[Amiga CD32]] (1993), a 32-bit CD-ROM games console produced until mid 1994. Although discontinued after Commodore's demise it met with moderate commercial success in Europe. The CD32 was a next-generation CDTV, and it was designed and released by Commodore before the PlayStation. It was Commodore's last attempt to enter the ever growing video-game console market.

Following purchase of Commodore's assets by Escom in 1995, the A1200 and A4000T continued to be sold in small quantities until 1996, though the ground lost since the initial launch and the prohibitive expense of these units meant that the Amiga line never regained any real popularity.

Several Amiga models contained references to songs by the [[rock music|rock]] band [[The B-52's]]. Early A500 units had the words "B52/ROCK LOBSTER"<ref name="AutoP5-16" /> [[PCB manufacturing|silk-screen printed]] onto their [[printed circuit board]], a reference to the song "[[Rock Lobster]]" The [[Amiga 600]] referenced "JUNE BUG" (after the song "Junebug") and the [[Amiga 1200]] had "CHANNEL Z" (after "[[Channel Z (song)|Channel Z]]"),<ref name="AutoP5-17" /> and the CD-32 had "Spellbound."

=== AmigaOS 4 systems ===
{{Main|AmigaOS 4}}

[[AmigaOS 4]] is designed for PowerPC Amiga systems. It is mainly based on AmigaOS 3.1 source code, with some parts of version 3.9. Currently runs on both Amigas equipped with CyberstormPPC or BlizzardPPC accelerator boards, on the Teron series based [[AmigaOne]] computers built by [[Eyetech]] under license by [[Amiga, Inc.]], on the [[Pegasos|Pegasos II]] from [[Genesi]]/[[Genesi|bPlan GmbH]], on the [[ACube Systems Srl]] [[Sam440ep]] / [[Sam460ex]] / AmigaOne 500 systems and on the A-EON [[AmigaOne X1000]].

AmigaOS 4.0 had been available only in developer pre-releases for numerous years until it was officially released in December 2006.<ref name="AutoP5-18" /> Due to the nature of some provisions of the contract between Amiga Inc. and [[Hyperion Entertainment]] (the Belgian company that is developing the OS), the commercial AmigaOS 4 had been available only to licensed buyers of AmigaOne motherboards.

AmigaOS 4.0 for Amigas equipped with PowerUP accelerator boards was released in November 2007.<ref name="AutoP5-19" /> Version 4.1 was released in August 2008 for AmigaOne systems,<ref name="AutoP5-20" /><ref name="AutoP5-21" /> and in May 2011 for Amigas equipped with PowerUP accelerator boards.<ref name="AutoP5-22" /> The most recent release of AmigaOS for all supported platforms is 4.1 update 5.<ref name="AutoP5-23" /> Starting with release 4.1 update 4 there is an Emulation drawer containing official AmigaOS 3.x ROMs (all classic Amiga models including CD32) and relative Workbench files.

[[Acube Systems]] entered an agreement with Hyperion under which it has ported AmigaOS 4 to its [[Sam440ep]] and [[Sam460ex]] line of PowerPC-based motherboards.<ref name="AutoP5-24" /> In 2009 a version for [[Pegasos II]] was released in co-operation with Acube Systems.<ref name="AutoP5-25" /> In 2012, A-EON Technology Ltd manufactured and released the [[AmigaOne X1000]] to consumers through their partner, Amiga Kit who provided end-user support, assembly and worldwide distribution of the new system.

=== Amiga hardware clones ===
Long-time Amiga developer MacroSystem entered the Amiga-clone market with their [[DraCo]] non-linear video editing system.<ref name="AutoP5-26" /> It appears in two versions, initially a tower model and later a cube. DraCo expanded upon and combined a number of earlier expansion cards developed for Amiga (VLabMotion, Toccata, WarpEngine, RetinaIII) into a true Amiga-clone powered by the [[Motorola 68060]] processor. The DraCo can run AmigaOS 3.1 up through AmigaOS 3.9. It is the only Amiga-based system to support [[FireWire]] for video [[I/O]]. DraCo also offers an Amiga-compatible [[Amiga Zorro III|Zorro-II]] expansion bus and introduced a faster custom DraCoBus, capable of {{nowrap|30&nbsp;MB/sec}} transfer rates (faster than Commodore's [[Amiga Zorro III|Zorro-III]]). The technology was later used in the Casablanca system, a set-top-box also designed for non-linear video editing.

In 1998, Index Information released the Access, an Amiga-clone similar to the Amiga 1200, but on a motherboard that could fit into a standard {{fraction|5|1|4}}-inch [[drive bay]]. It features either a [[68020]] or [[68030]] CPU, with a [[Amiga Advanced Graphics Architecture|AGA]] chipset, and runs AmigaOS 3.1.

In 1998, former Amiga employees (John Smith, Peter Kittel, [[Dave Haynie]] and Andy Finkel to mention few) formed a new company called PIOS. Their hardware platform, PIOS One, was aimed at Amiga, Atari and Macintosh users. The company was renamed to Met@box in 1999 until it folded.<ref name="AutoP5-27" />

The NatAmi (short for ''Native Amiga'') hardware project began in 2005 with the aim of designing and building an Amiga clone motherboard that is enhanced with modern features.<ref name="AutoP5-28" /> The NatAmi motherboard is a standard [[Mini-ITX]]-compatible form factor computer motherboard, powered by a Motorola/Freescale 68060 and its chipset. It is compatible with the original Amiga chipset, which has been inscribed on a programmable FPGA [[Altera]] chip on the board. The NatAmi is the second Amiga clone project after the [[Minimig]] motherboard, and its history is very similar to that of the [[C-One]] mainboard developed by [[Jeri Ellsworth]] and Jens Schönfeld. From a commercial point of view, Natami's circuitry and design are currently [[closed source]].{{Citation needed|date=June 2011}} One goal of the NatAmi project is to design an Amiga-compatible motherboard that includes up-to-date features but that does not rely on emulation (as in [[WinUAE]]), modern PC [[Intel]] components, or a modern [[PowerPC]] mainboard. As such, NatAmi is not intended to become another evolutionary heir to classic Amigas, such as with [[AmigaOne]] or [[Pegasos]] computers. This "purist" philosophy essentially limits the resulting processor speed but puts the focus on bandwidth and low latencies. The developers also recreated the entire Amiga chipset, freeing it from legacy Amiga limitations such as two [[megabyte]]s of audio and video graphics RAM as in the [[Amiga Advanced Graphics Architecture|AGA chipset]], and rebuilt this new chipset by programming a modern [[FPGA]] [[Altera]] Cyclone IV chip. Later, the developers decided to create from scratch a new software-form processor chip, codenamed "N68050" that resides in the physical Altera FPGA programmable chip.<ref name="AutoP5-29" />

In 2006, two new Amiga clones were announced, both using FPGA-based hardware synthesis to replace the Amiga [[Amiga Original Chip Set|OCS]] custom chipset. The first, the [[Minimig]], is a personal project of Dutch engineer Dennis van Weeren. Referred to as "new Amiga hardware",<ref name="minimig" /> the original model was built on a [[Xilinx]] Spartan-3 development board, but soon a dedicated board was developed. The minimig uses the FPGA to reproduce the custom Denise, Agnus, Paula and [[Amiga custom chips#Gary|Gary]] chips as well as both 8520 [[MOS Technology CIA|CIAs]] and implements a simple version of [[Amiga custom chips#Amber|Amber]]. The rest of the chips are an actual 68000 CPU, ram chips, and a PIC microcontroller for [[BIOS]] control.<ref name="minimig" /> The design for Minimig was released as [[Open-source software|open-source]] on July 25, 2007. In February 2008, an Italian company [[Acube Systems]] began selling Minimig boards. A third party upgrade replaces the PIC microcontroller with a more powerful ARM processor, providing more functionality such as write access and support for hard disk images. The Minimig core has been ported to the FPGArcade "Replay" board. The Replay uses an FPGA with about three times more capacity and that does support the AGA chipset and a [[68020]] [[Soft core (synthesis)|soft core]] with [[68030]] capabilities. The Replay board is designed to implement many older computers and classic arcade machines.

The second is the Clone-A system announced by [[Individual Computers]]. As of mid-2007 it has been shown in its development form, with FPGA-based boards replacing the Amiga chipset and mounted on an Amiga 500 motherboard.<ref name="individual" />
