The Indigo was designed to run IRIX, SGI's version of Unix. [2] The Indigos with R3000 processors are supported up to IRIX version 5.3, and Indigo equipped with an R4000 or R4400 processor can run up to IRIX 6.5.22.
SGI Indigo2 IMPACT and a promotional SGI espresso machine in an Indigo case Indigo2 IMPACT R10000 Badge for a Power Indigo2 with Extreme Graphics. The SGI Indigo2 (stylized as "Indigo 2") and the SGI Challenge M are Unix workstations which were designed and sold by SGI from 1992 to 1997. The Indigo2, codenamed "Fullhouse", is a desktop workstation.
Silicon Graphics, Inc. (stylized as SiliconGraphics before 1999, later rebranded SGI, historically known as Silicon Graphics Computer Systems or SGCS) was an American high-performance computing manufacturer, producing computer hardware and software.
The Indy, code-named "Guinness", is a low-end multimedia workstation introduced on July 12, 1993 by Silicon Graphics Incorporated (SGI). SGI developed, manufactured, and marketed Indy as the lowest end of its product line, for computer-aided design (CAD), desktop publishing, and multimedia markets.
A unifying feature across all IRISes – 68K, Professional, Personal, PowerSeries, Indigo, Crimson, and Onyx – is a proprietary serial-based keyboard/mouse protocol. Earlier machines use either a DE-15 (68K, Professional, PowerSeries) or DE-9 (4D/20, /25) connector, with the later machines (4D/30, /35, Indigo, Crimson, Onyx) using a mini DIN ...
Silicon Graphics, Inc. (SGI)-made workstations, i.e., SGI's high-end computer graphics desktop machines. In much of the 1980s and 1990s, these computers were much used for producing, e.g., 3D graphics in movies.
Extreme Graphics systems consist of eight Geometry Engines and two Raster Engines, twice as many units as the Elan/XZ graphics used in the Indy, Indigo, and Indigo2. The eight geometry engines are rated at 256 MFLOPS maximum, far faster than the MIPS R4400 CPU used in the workstation.
The Silicon Graphics Indigo Elan option Graphics systems consist of four GE7 Geometry Engines capable of a combined 128 MFLOPS and one RE3 Raster Engine. Together, they are capable of rendering 180K Z-buffered, lit, Gouraud-shaded triangles per second. The framebuffer has 56 bits per pixel, causing 12-bits per pixel (dithered RGB 4/4/4) to be ...
