Silicon Graphics Inc., more commonly known as SGI, produced a series of 3D graphics hardware architectures beginning in the mid 1980s. Their first product line was the IRIS series of terminals and workstations based on the Motorola 68000 processor. Over the years that I’ve been building the collection for my museum of computer graphics history, I’ve managed to obtain most of the SGI product line except for the first generation IRIS machines and the Fuel and Tezro which are still too expensive. Recently I came across an opportunity to get an SGI IRIS 3130. This is the largest model in the IRIS product line which consists of the IRIS 1000, IRIS 2000 and IRIS 3000 series machines. The IRIS machines were featured in an episode of Computer Chronicles from April 5th, 1984. I’ve got some pictures of the IRIS 3130 I’ve acquired on picasaweb.
