I recently had an email reply from someone who had once had access to the Klingon-modded version of flight on an SGI 3130. Sadly, he no longer had access to the 3130. In his email, he also told me:
Does anyone have any idea from this (rather vague) description what this machine could have been?I personally had another SGI that I think had that version of flight installed, but my wife forced me to get rid of that machine. It was as big as a small refrigerator, bigger than the old 3130. I wish I had that machine still.
