NeXTcube Turbo

The NeXTcube Turbo is a high-end workstation computer developed, manufactured and sold by NeXT. It superseded the earlier NeXTcube workstation and is housed in the same cube-shaped magnesium enclosure. The workstation runs the NeXTSTEP operating system.

Hardware
The NeXTcube Turbo is a development of the earlier NeXTcube. It differs from its predecessor in having a 33 MHz 68040 processor.

The NeXTdimension board can also be used in the NeXTcube Turbo.

There was also a very rare accelerator board known as the Nitro; between 5 and 20 are estimated to have been made. It increased the speed of a NeXTcube Turbo by replacing the standard 33 MHz processor with a 40 MHz one.
