These SGI Indigo 2 xZ is based on the same "Express Graphics" architecture from the original SGI Indigo 2, but feature improved performance.

Released in January 1993, the Indigo 2, codenamed "Fullhouse", was the successor to SGI's Indigo workstation.  The Indigo 2 was marketed as a high-end workstation, with many configurations totaling well over $100,000 (USD), and thus was placed above the "budget” SGI Indy workstation released several months later. Like any other SGI workstation, the Indigo 2 was mostly used in academic and commercial settings, with very little value or use to the personal computer market. 

Classifying specific specifications is made difficult by the highly customizable nature of SGI’s workstations.  This issue become even more convoluted by the 1995 release of the Indigo 2 Impact. Like the Indy, the Indigo 2 and Indigo 2 Impact belong to the group of colourful and iconic "pizza box” workstations meant to fit underneath a monitor. Both versions are easily differentiated by the colour of their case with the base Indigo 2 teal and the Indigo 2 Impact purple.  There is also an additional rare POWER Indigo 2 version which featured a R8000 processor in a teal case.
