The NeXT Computer is a workstation computer developed, marketed, 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 runs the Mach- and BSD-derived, Unix-based NeXTSTEP operating system, with a proprietary GUI using a Display PostScript-based back end. The motherboard is square and fits into one of four identical slots in the enclosure. The NeXT Computer enclosure consists of a 1-foot (305 mm) die-cast magnesium cube-shaped, black case, which led to the machine being informally referred to as "The Cube". It was launched in 1988 at US$6,500 ($12,962 in 2015).
After Jobs was forced out of Apple in 1985, he started a company that built workstation computers. The NeXT Computer was introduced in 1988 at a lavish launch event. Tim Berners-Lee created the world's first web browser on the NeXT Computer. The NeXT Computer was the basis for today's Macintosh OS X and iPhone operating system (iOS).
The NeXT Computer was succeeded by the NeXTcube, an upgraded model, in 1990.
