Cool grab... Any clue what you actually got in it? 4500? 4600? The "dream" R5000? How about video? Is it the common 8XL, or the full blown XGE? The crappy XZ?
Back in the late '90's I had my own computer store, and one of my main clients was the local UPS office which in a laughable and pathetic waste of tech had a R5000 XGE acting as a X-Server to their main office's mainframe... When they finally stopped using it they let me have it, but sadly it "disappeared" (along with a number of other things) during one of my moves... Always wanted to grab another one as the video processing capabilities were a hoot to play with at the time.
