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.
Commodore International was an American home computer and electronics manufacturer founded by Jack Tramiel. Commodore International (CI), along with its subsidiary Commodore Business Machines (CBM), was a significant participant in the development of the home computer industry in the 1970s to early 1990s. In 1982, the company developed and marketed the world's second-best selling computer, the Commodore 64, and released its Amiga computer line in July 1985. Commodore was one of the world's largest personal computer manufacturers, with sales peaking in the last quarter of 1983 at $49 million.
The Motorola 68060 ("sixty-eight-oh-sixty") is a 32-bit microprocessor from Motorola released in 1994. It is the successor to the Motorola 68040 and is the highest performing member of the 68000 series. Two derivatives were produced, the 68LC060 and the 68EC060.
The NewTek Video Toaster is a combination of hardware and software for the editing and production of NTSC standard-definition video. The plug-in expansion card initially worked with the Amiga 2000 computer and provides a number of BNC connectors on the exposed rear edge that provide connectivity to common analog video sources like VHS VCRs. The related software tools support video switching, luma keying, character generation, animation, and image manipulation.
ATI Technologies Inc., commonly called ATI, was a Canadian semiconductor technology corporation based in Markham, Ontario, that specialized in the development of graphics processing units and chipsets. Founded in 1985, the company listed publicly in 1993 and was acquired by AMD in 2006. As a major fabrication-less or fabless semiconductor company, ATI conducted research and development in-house and outsourced the manufacturing and assembly of its products. With the decline and eventual bankruptcy of 3dfx in 2000, ATI and its chief rival Nvidia emerged as the two dominant players in the graphics processors industry, eventually forcing other manufacturers into niche roles.
MorphOS is an AmigaOS-like computer operating system (OS). It is a mixed proprietary and open source OS produced for the Pegasos PowerPC (PPC) processor based computer, PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the Efika and mobileGT. Since MorphOS 2.4, Apple's Mac mini G4 is supported as well, and with the release of MorphOS 2.5 and MorphOS 2.6 the eMac and Power Mac G4 models are respectively supported. The release of MorphOS 3.2 added limited support for Power Mac G5. The core, based on the Quark microkernel, is proprietary, although several libraries and other parts are open source, such as the Ambient desktop.
The Amiga 3000T is a computer manufactured by Commodore. It is closely related to the Amiga 3000, although it came in a tower case which offers greater expandability. The case for the prototype, the 3500, was derived from Commodore's PC compatible line.
The Catweasel is a family of enhanced floppy-disk controllers from German company Individual Computers. These controllers are designed to allow more recent computers, such as PCs, to access a wide variety of older or non-native disk formats using standard floppy drives.
Cirrus Logic Inc. is an American fabless semiconductor supplier that specializes in analog, mixed-signal, and audio DSP integrated circuits (ICs). Since 1998, the company's headquarters have been in Austin, Texas.
Orchid Technology was a privately held company founded by Le Nhon Bui in 1982.
Applied Engineering, headquartered in Carrollton, Texas, was a leading third-party hardware vendor for the Apple II series of computers from the early 1980s until the mid-1990s.
Phase5 Digital Products is a defunct German computer hardware manufacturer that developed third-party hardware primarily for the Amiga platform. Their most popular products included CPU upgrade boards, SCSI controllers and graphics cards.

The TMS34010, developed by Texas Instruments and released in 1986, was the first programmable graphics processor integrated circuit. While specialized graphics hardware existed earlier, such as blitters, the TMS34010 chip is a microprocessor which includes graphics-oriented instructions, making it a combination of a CPU and what would later be called a GPU. It found use in arcade video games from the late 1980s through the mid 1990s, including Mortal Kombat and NBA Jam, and computer workstation video accelerator boards. TI later released the TMS34020 with an emphasis on 3D rendering.
The Amiga is a family of home computers that were designed and sold by the Amiga Corporation from 1985 to 1994.
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.
The ATI Mach line was a series of 2D graphics accelerators for personal computers developed by ATI Technologies. It became an extension to the ATI Wonder series of cards. The first chip in the series was the ATI Mach8. It was essentially a clone of the IBM 8514/A with a few notable extensions such as Crystal fonts. Being one of the first graphics accelerator chips on the market, the Mach8 did not have an integrated VGA core. In order to use the first Mach8 coprocessor cards, a separate VGA card was required. This increased the cost of ownership as one had to purchase two rather than one expansion card for graphics. A temporary solution was presented with the ATI Graphics Ultra/Vantage cards, which combined an ATI 8514 Ultra and VGA Wonder+ into a single card. The Mach32 chip was the follow-up to the Mach8, which finally featured an integrated VGA core, true colour support and a 64-bit datapath to internal memory.
PowerUP boards were dual-processor accelerator boards designed by Phase5 Digital Products for Amiga computers. They had two different processors, a Motorola 68000 series (68k) and a PowerPC, working in parallel, sharing the complete address space of the Amiga computer system.
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.
