The Commodore 900 (also known as the Z-8000) was a prototype microcomputer intended for business computing and CAD purposes, and created in 1985 by Commodore International in West Germany. The project was cancelled when Commodore bought Amiga. All of the prototypes were sold as scrap to 3rd party distributors. Only very few of these units may have survived.
The C900 was a 16-bit computer based on the segmented version of the Zilog Z8000 CPU. It ran Coherent, a UNIX-like operating system. Two versions of the machine were developed: a workstation with 1024×800 pixels graphics, and a server with text-only display.
The C900's case is similar to the Amiga 2000's but slightly larger.
