AmigaOS was a truly multitask operating system too.
Under the hood, it packed a Motorola 68000 CPU (7.16MHz NTSC, 7.09MHz PAL) upgradable officially to a 68010 and to other CPUs via third party route. While the 68000 was common in 1985, the Amiga 1000 features three additional co-processors for multimedia operations.
The Amiga 1000 had 256 KB of Amiga Chip RAM, which was officially upgradable to 512 KB and further with third party upgrades. Further hardware upgrades were possible through the included 86-pin expansion port.
When the Amiga 500 model launched a couple of years after for a cut price of $700, it established Amiga as a popular gaming system, with sales of around 6 million units.
