SGI R4000 Indigo Elan (S/F)

Introduced in 1991, the Indigo was considered one of the most capable graphics workstations of its era, and was essentially peerless in the realm of hardware-accelerated three-dimensional graphics rendering. For use as a graphics workstation, the Indigo was equipped with a two-dimensional framebuffer or, for use as a 3d-graphics workstation, with the Elan graphics subsystem including one to four Geometry Engines (GEs). Indigo was used in the Command Center of Jurassic Park.
