The A1000, or Commodore Amiga 1000, was Commodore's initial Amiga personal computer, introduced on July 23, 1985 at the Lincoln Center in New York City. Machines began shipping in September with a base configuration of 256 kB of RAM at the retail price of 1,295 USD. A 13-inch (330 mm) analog RGB monitor was available for around 300 USD bringing the price of a complete Amiga system to 1,595 USD. Before the release of the Amiga 500 and A2000 models in 1987, the A1000 was simply called Amiga.

In the US, the A1000 was marketed as The Amiga from Commodore, however the Commodore logo was omitted from the casing. Additionally the Amiga 1000 was exclusively sold in computer stores, rather than the various non-computer related stores the Commodore 64 were retailed in. These measures were an effort to avoid Commodore's "toy-store" computer image created during the Tramiel era.[1][2]

Design

The A1000 had a number of characteristics that distinguished it from later Amigas: It was the only model to feature the short-lived Amiga "checkmark" logo on its case; the case was elevated slightly to give a storage area for the keyboard when not in use (a "keyboard garage"); and the inside of the case was engraved with the signatures of the Amiga designers, including Jay Miner, and the paw print of his dog Mitchy. The A1000's case was designed by Howard Stolz[3] As Senior Industrial Designer at Commodore, Stolz was the mechanical lead and primary interface with Sanyo in Japan, the contract manufacturer for the A1000 casing.[4]

Because Workbench was rather buggy at the time of the A1000's release, the OS was not placed in ROM. Instead, the A1000 included a daughterboard with 256 KB of RAM, dubbed the "Writable Control Store" (WCS), into which the core of the operating system was loaded from floppy disk (this portion of the operating system was known as the "Kickstart"). The WCS was write-protected after loading, and system resets did not require a reload of the WCS. In Europe the WCS was often referred to as WOM (Write Once Memory) rather than the more conventional ROM (Read Only Memory).

Many A1000 owners remained attached to their machines long after newer models rendered the units technically obsolete, and it attracted numerous aftermarket upgrades. Many CPU upgrades that plugged into the Motorola 68000 socket functioned in the A1000. Additionally, a line of products called the Rejuvenator series allowed the use of newer chipsets in the A1000, and an Australian-designed replacement A1000 motherboard called The Phoenix utilized the same chipset as the A3000 and added an A2000-compatible video slot and onboard SCSI controller.
