This was my first for foray into any kind of networking. I remember not exactly knowing what it was, but I saved up $100 and asked the guy in the store if he know any numbers I could call to connect with other computers. He gave me a number to a local BBS (Bulletin Board System) and I made my first call shortly after I got home. The excitement I experienced when I had my first chat was insane! I ran around my house gathering everyone in my family to come and see. It was great! The best part was that at 300 baud, the text scrolled about as fast as I could read it down the screen. Ah the good old days.
