The NeXT Computer (also called the NeXT Computer System) is a workstation computer developed, manufactured, and sold by NeXT Inc., a company founded by Steve Jobs and several other veterans of the Macintosh and Lisa teams, from 1988 until 1990. It ran the Mach- and BSD-derived, Unix-based NeXTSTEP operating system, with a unique GUI using a Display PostScript-based back end. The motherboard is square and fit into one of four identical slots in the enclosure. The NeXT Computer enclosure consisted of a 1-foot (305 mm) die-castmagnesium cube-shaped, black case, which led to the machine being informally referred to as "The Cube". It cost US$6,500.
The NeXT Computer was succeeded by the NeXTcube, an upgraded model, in 1990.
The NeXT Computer was not a great commercial success at the level of high volume personal computers such as the Apple II, the Macintosh, or MicrosoftWindows PCs; some of the workstations were sold to universities, financial institutions, and government agencies however.
