NeXTcube

The NeXTcube is a high-end computer developed, manufactured, and sold by NeXT from 1990 until 1993. It superseded the original NeXT Computer workstation and is housed in a similar cube-shaped magnesium enclosure, sometimes called the "Cube II". The workstation runs the NeXTSTEP operating system and was launched with a 10,000 list price.

Hardware
The NeXTcube is the successor to the original NeXT Computer. It differs from its predecessor in having a 25 MHz Motorola 68040 processor, larger hard disks in place of the, and an optional floppy disk drive. A faster 33 MHz NeXTcube Turbo was produced later.

NeXT released the NeXTdimension for the NeXTcube, a based on an  processor, which offers 32-bit PostScript color display and video-sampling features.

The Pyro accelerator board increases the speed of a NeXTcube by replacing the original 25 MHz 68040 processor with a 50 MHz version.
