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 It superseded the earlier [NeXTcube](/source/NeXTcube) workstation and is housed in the same cube-shaped magnesium enclosure.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

## Hardware

The NeXTcube Turbo is a development of the earlier NeXTcube. It differs from its predecessor in having a 33 MHz [68040](/source/Motorola_68040) processor.

The [NeXTdimension](/source/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.[2]
