The NeXT Computer (also called the NeXT Computer System) 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 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.
The NeXT Computer was revealed at a lavish (invitation only) gala launch event "NeXT Introduction - the Introduction to the NeXT Generation of Computers for Education" at the Louise M. Davies Symphony Hall, San Francisco, California on Wednesday October 12 1988. The following day, selected educators and software developers were invited (for $100 registration fee) to attend the first public technical overview of the NeXT computer at an event called "The NeXT Day" held at the San Francisco Hilton. This event gave developers interested in developing NeXT software an insight into the software architecture, object-oriented programming and developing for the NeXT Computer. The luncheon speaker was Steven P. Jobs.
