NeXTstation
NeXTstation is a high-end workstation computer developed, manufactured and sold by NeXT from 1990 until 1993. It runs the NeXTSTEP operating system. Overview. The NeXTstation was released as a more affordable alternative to the NeXTcube at about or about half the price. Several models were produced, including the NeXTstation (25 MHz), NeXTstation Turbo (33 MHz), NeXTstation Color (25 MHz) and NeXTstation Turbo Color (33 MHz). In total, NeXT sold about 50,000 computers (not including sales to government organizations), making the NeXTstation a rarity today. The NeXTstation originally shipped with a NeXT MegaPixel Display 17" monitor (with built-in  speakers), keyboard, and mouse. It is nicknamed "the slab", since the pizza box form factor contrasts quite sharply with the original NeXT Computer's basic shape (otherwise known as "the cube"). The Pyro accelerator board increases the speed of a NeXTstation by replacing the standard 25 MHz processor with a 50 MHz one. 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 NeXTstation Turbo by replacing the standard 33 MHz processor with a 40 MHz one.
