The Amiga 1000, also known as the A1000, is the first personal computer released by Commodore International in the Amiga line. It combines the 16/32-bit Motorola 68000 CPU which was powerful by 1985 standards with one of the most advanced graphics and sound systems in its class. It runs a preemptive multitasking operating system that fits into 256 KB of read-only memory[1][4][5] and was shipped with 256 KB of RAM.[2] The primary memory can be expanded internally with a manufacturer-supplied 256 KB module for a total of 512 KB of RAM. Using the external slot the primary memory can be expanded up to 8.5 MB.[2]

The Amiga OS remains one of the great operating systems of the past 20 years, incorporating a small kernel and tremendous multitasking capability the likes of which have only recently been developed in OS/2 and Windows NT. The biggest difference is that the Amiga OS could operate fully and multitask in as little as 256K of address space. Even today, the OS is only about 1MB in size. And to this day, there is very little a memory-hogging, CD-ROM-loading OS can do the Amiga can't. Tight code—there's nothing like it.
    I've had an Amiga for maybe a decade. It's the single most reliable piece of equipment I've ever owned. It's amazing! You can easily understand why so many fanatics are out there wondering why they are alone in their love of the thing. The Amiga continues to inspire a vibrant—albeit cultlike—community, not unlike that which you have with Linux, the Unix clone.
