Circa this year, plus or minus a lot, I attached modems to my Commodore 64 (and, later, PC) to connect to local dial-up BBSes, such as “Hogan’s Alley IV” and “Doctor On Board”. Even just 300 baud was fun, though I was, of course, happy to upgrade to 1200, 2400, and more, as it became possible to do so. Some of the BBSes were even part of FidoNet, which let me exchange messages with people across the whole planet, on any topic that I wanted!
