A deep dive into the Silicon Graphics Indigo² IMPACT 10000
This beautiful purple slab is the Silicon Graphics Indigo² (though, unlike its earlier namesake, not actually indigo coloured) with the upper-tier MIPS R10000 CPU and IMPACT graphics. My recollection was that it worked at the time, but I couldn’t remember if it booted, and of course that was no guarantee that it could still power on. If this machine is to stay working and in the collection, we’re gonna need a Refurb Weekend.

Out of all the retro UNIX workstations of old, the machines from SGI are both the most popular, the most well-known, and thus, also some of the most expensive. Yet, at the same time, everything up until the very last generation or two of MIPS IRIX workstations, generally do not seem to be particularly rare either. The community around SGI’s machines and IRIX is also quite thriving still, much more so than the communities of the other commercial UNIX variants. Still, the odds of me completing my collection of final-generation commercial UNIX workstations are low, exactly because of just how rare and stupidly expensive the SGI Tezro is.
As always, Cameron Kaiser goes into a level of detail few other people in the world do when it comes to rare or special computers, and this article about the Silicon Graphics Indigo² is no exception. Detailed photographs, an in-depth history of the machine, detailed descriptions of the hardware, the various fixes that needed to be performed, getting it back up and running, and everything else. There’s really nobody else writing these kinds of articles.
The weekend’s here, so sit back, relax, and have fun.
