Commodore 900

The CBM 900 was a computer system by Commodore, which was developed as a server and workstation variant of the early 1980s, but never produced in series. As a Zilog Z8001 CPU was used at 10 MHz, and the main memory with 512 KB RAM; and this could be expanded to up to 2MB. As a graphic or video chip, the MOS 8563 VDC was developed which was later used in the C128. The prototype had a 20 MB hard drive and ran with the operating system Coherent.

The computer never went into production, partly because at that time the company Commodore Amiga took over and brought into the race with the products marketed under this brand computers, particularly Amiga 1000 and Amiga 2000, more efficient alternatives to the C900. The housing design is only apparently identical to the Amiga 2000, not least because it is a little larger in size.
