I must be very old, but I was sort of online-ish in 1985/6. At my university, we had access from VAXes and PDPs on the local network via BITnet to other universities, and I clearly remember chatting and emailing with friends and teachers in other towns, using such easily remembered names as EDH%HNYKUN52. There was also limited access to usenet groups, but that was so specialized back then, that I didn't pay attention of it. I also remember getting my first modem, a 1200 baud one, and later running Archie and Gopher over dial-up connections. Can't say I'm nostalgic about that, though.
