Comodore Amiga 1000, sometimes called A1000 or simply Amiga, was first in the range and was running AmigaOS 1.0. Its configuration was quite basic, yet, powered up by a Motorola 68000 @ 7.16 MHz (PAL) processor, with 256-512 KB (8.5 maximum) RAM, resolution 640 x 512i, it was quite advanced at the time.
The Amiga 1000 was replaced by Amiga 2000 in 1987.

In 1994, as Commodore filed for bankruptcy, Byte magazine called the Amiga 1000 “the first multimedia computer… so far ahead of its time that almost nobody—including Commodore’s marketing department—could fully articulate what it was all about”
In 2006, PC World rated the Amiga 1000 as the 7th greatest PC of all time. In 2007, it was rated by the same magazine as the 37th best tech product of all time.
