I bought this from Retro Computing Group member Jon. He and our fellow member, Michael, acquired a few units and swapped parts to get a some reliable systems. This one received a Sony power supply in place of the original which was a somewhat unreliable type (by reputation) and an additional disk (not sure if there’s a problem with the original). Michael installed Irix 6.5.
The unit itself was in good condition and came with SGI monitor, keyboard, mouse (not working), and video camera. It also had some books and installation media.
