SGI IRIS
The SGI IRIS series of terminals and workstations from Silicon Graphics was produced in the 1980s and 1990s. IRIS is an acronym for Integrated Raster Imaging System. Overview 68000 The early systems up to IRIS 3000 use the Motorola 68000 series of processors originally, and later models feature early-generation MIPS processors. These systems run the GL2 operating system, a predecessor of the IRIX operating system, which is based on UniSoft UniPlus System V Unix. GL2 uses a proprietary windowing system named MEX (windowing system), mex (Multiple EXposure). The first model, the IRIS 1000, was shipped around November 1983 with an 8 MHz Motorola 68000 CPU. It is a graphics terminal intended to be attached to a VAX-11 system running either VAX/VMS or BSD Unix. The related IRIS 1200 terminal has a 20-slot backplane in its cabinet versus the 10-slot backplane of the IRIS 1000. The IRIS 1400 Workstation (also known as the IRIS Workstation) was shipped only in 1984. It has a 10 MHz Moto ...

Silicon Graphics
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. Founded in Mountain View, California in November 1981 by Jim Clark, its initial market was 3D graphics computer workstations, but its products, strategies and market positions developed significantly over time. Early systems were based on the Geometry Engine that Clark and Marc Hannah had developed at Stanford University, and were derived from Clark's broader background in computer graphics. The Geometry Engine was the first very-large-scale integration (VLSI) implementation of a geometry pipeline, specialized hardware that accelerated the "inner-loop" geometric computations needed to display three-dimensional images. For much of its history, the company focused on 3D imaging and was a major supplier of both hardware and softwa ...
