"first" computer on the internet

- My recollection is what had been called the ARPAnet became the "Internet" around 1982, certainly we were calling it the "Internet" by '84-85. The transition to the 5 .mil/.edu/.net/.gov/.com domains was in that time period as well. It was a "large", functioning, useful network by that time, not just an experimental/prototype system. - IIRC, the NSFnet funding/expansion/backbone were slightly later. - As one who was developing (X.400) multi-node store-and-forward email systems starting in 1982-3, and was involved in establishing such a Canada-wide and world-wide functioning email network by 1984-5, by which time "Internet" email was already very well-established, I won't bother making any further comment about email firsts. - The "<user>(a)<subd>.<subd>.<domain>" address format was also well-established by the early '80s. The machine Dan has may have been 'first' at something but without a further qualifier any claim of historic significance is pointless. Given the ~1990 date, I was guessing it might have something to do with the opening of the internet to the public: first machine to route to a public ISP?, first machine to provide SLIP access?, who knows...? I'm not familiar with the model of machine mentioned so even those random guesses may be well off.
