This amazing website contains lots of great technical information on SGI. Many of my students have no idea what SGI is, which is unfortunate, but a quick Wikipedia read is just a Google search away. I grew up with some SGI machines, where I remember running some of my first CFD codes on late at night. SGI might not always be the tech. leader in performance, but their machines had the most style! That should count for something when today Macs have done so well on the open market.
