My first online experience dates back to using a brand new 300 baud modem for our Commodore 64 to connect to a BBS that I had sent away for information about called LoadStar. After a few months of playing around, my parents realized just how much their phone bill was getting hit for, and my few long distance calls to BBSs in California didn't help either ($2.99/minute long distance or something like that). I was grounded and the modem was put away for years. By the time we got a blazingly fast 486sx 33Mhz computer I was again allowed online, but only to call up nearby friends from high school for some games. then came Rise of the Triad and going to college and getting my first email address (still works too, 17 years later)!
Wow, I've been online longer than most college freshmen have been alive.
