The SGI O2's direct successor was the SGI Fuel, a high-end workstation primarily based around a single R14000 MIPS CPU. SGI introduced the Fuel in January 2002 with a list price of US$11,495. Its larger sibling is the SGI Tezro. ...more on Wikipedia about "SGI Fuel"
The SGI Indigo was a line of computer workstations manufactured by SGI beginning in 1990. The initial Indigo (codename Hollywood) was based on the IP12 processor board, which contained a 32-bit MIPS R3000A RISC processor soldered on the board and proprietary memory slots. The later version (codename Blackjack) was based on the IP20 processor board, which had a removable processor module (PM1 or PM2) containing a 64-bit MIPS R4000 or R4400 processor. The IP20 used standard 72-pin DIMMs with parity. ...more on Wikipedia about "SGI Indigo"
The SGI Indigo² and the SGI Challenge M were Unix computers marketed by SGI from 1993 to 1997. The Indigo² was a desktop workstation. The Challenge M was a server which differed from the Indigo² only by a slightly differently colored and badged case, and the absence of graphics and sound hardware. Both systems were based on the MIPS processors. ...more on Wikipedia about "SGI Indigo² and Challenge M"
The Indy was the fruit of SGI's effort to muscle into the market for desktop publishing, low-end CAD, and multimedia. At the time, the market was mostly dominated by Apple. The Indy was the first computer to include a digital video camera, and was built with a (then) forward-looking architecture including an on-board ISDN adapter. With the inclusion of analog and digital I/O, SCSI, and standard composite and S-Video inputs, the Indy really was a multimedia machine. ...more on Wikipedia about "SGI Indy"
The O2 is an entry-level Unix workstation introduced in 1996 by Silicon Graphics (SGI) to replace their earlier Indy series. Like the Indy, the O2 used a single MIPS-based CPU and was intended to be used primarily for multimedia. It's larger counterpart was the SGI Octane The O2 was replaced by the Fuel series in 2002. ...more on Wikipedia about "SGI O2"
The SGI Octane (and the very similar SGI Octane2) are UNIX workstations marketed by SGI. Both are SMP-capable (up to 2 identical processors) workstations, originally based on the MIPS architecture R10000 processor. Newer Octanes are based on MIPS R12000 and R14000. Octane2 has four improvements compared to Octane. Octane2 has revised power supply, system-board and xbow. Octane2 also shipped with VPro graphics and supports all available VPro cards (V6, V8, V10 and V12). Later revision Octanes also included some of the improvements mentioned. The machines shared a codename "Racer" or "Speedracer" inside SGI. ...more on Wikipedia about "SGI Octane"
The SGI Tezro is the second most recently released (as of December 2005) series of high-end computer workstation available from SGI, and is the immediate successor to the SGI Octane line. The systems are available in both rack-mount and tower versions, and the series was released in June 2003 with a list price of $20,500. The Tezro was released alongside the SGI Onyx4 (and because of component sharing, the Onyx4 and rack-mountable Tezro share many components, including skins). ...more on Wikipedia about "SGI Tezro"
The SGI Visual Workstation series was a line of computer workstations manufactured by SGI and designed to run Windows NT and Linux. The Visual Workstations are notable for their use of the Intel Pentium II and Intel Pentium III processors (rather than the 64-bit MIPS RISC architecture usually used in SGI computer products), as well as for the unique departures from the standard IBM AT-derived architecture from which the great majority of Intel 386-based computers—for example, unlike virtually all other Intel Pentium-class systems, the Visual Workstations did not include a BIOS (often criticized as hackish and obsolete), in favor of a port of the same powerful ARCS firmware system used in all other contemporary SGI workstations. ...more on Wikipedia about "SGI Visual Workstation"
