The earliest Amiga 500 models use nearly the same Original Amiga chipset as the Amiga 1000.

Supported by these drives are double-sided disks with a capacity of 901,120 bytes, as well as 360- and 720-KB disks formatted for IBM PC compatibles. The second and third additional drives are installed by daisy-chaining them.

The user can also install up to three external floppy drives, either 3 + 1⁄ 2- or 5 + 1⁄ 4-inch, via the disk drive port. Also built in to the base of the computer is a 3 + 1⁄ 2-inch floppy disk drive.

The CPU implements a 32-bit model and has 32-bit registers, but it has a 16-bit main ALU and uses a 16-bit external data bus and a 23-bit address bus, providing a maximum of 16 MB of address space. It uses a Motorola 68000 microprocessor running at 7.15909 MHz in NTSC regions and 7.09379 MHz in PAL regions. All European versions the keyboard have an additional two keys, except for the British variety, which still uses 94 keys. The keyboard for Amiga 500s sold in the United States contains 94 keys, including ten function keys, four cursor keys, and a number pad. Outwardly resembling the Commodore 128 and codenamed " Rock Lobster" during development, the Amiga 500's base houses a keyboard and a CPU in one shell, unlike the Amiga 1000. By this time, the home market was strongly shifting to IBM PC compatibles with VGA graphics and the "low-cost" Macintosh Classic, LC, and IIsi models. Despite this, neither the A1200 nor the A600 replicated the commercial success of its predecessor. In late 1992, Commodore released the Amiga 1200, a machine closer in concept to the original Amiga 500, but with significant technical improvements.

The Amiga 500 Plus was virtually identical except for its new operating system, and in mid-1992, the two were discontinued and effectively replaced by the Amiga 600. It was bundled with the Cartoon Classics pack in the United Kingdom at £399, although many stores still advertised it as an 'A500'. In November 1991, the enhanced Amiga 500 Plus replaced the 500 in some markets. Also included was the Amiga video connector which allows the A500 to be used with a conventional CRT television. In October 1989, the Amiga 500 dropped its price from £499 to £399 and was bundled with the Batman Pack in the United Kingdom (from October 1989 to September 1990) which included the games Batman, F/A-18 Interceptor, The New Zealand Story and the bitmap graphics editor Deluxe Paint 2.

It was followed by a revised version of the computer, the Amiga 500 Plus, and the 500 series was discontinued in 1992. Although popular with hobbyists, arguably its most widespread use was as a gaming machine, where its graphics and sound were of significant benefit. It proved to be Commodore's best-selling model, particularly in Europe. The Amiga 500 was sold in the same retail outlets as the Commodore 64, as opposed to the computer store-only Amiga 1000. It competed directly against models in the Atari ST line. In North America and the UK it was released in October 1987 with a US$699/£499 list price. It was initially available in the Netherlands in April 1987, then the rest of Europe in May. 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.Ĭommodore announced the Amiga 500 at the January 1987 winter Consumer Electronics Show – at the same time as the high-end Amiga 2000.

The Amiga 500, also known as the A500, is the first low-end version of the Amiga home computer.
