I was introduced to the BBS scene by older peers & purchased my first 1200 baud modem soon after. Since the free calling area was limited, I mostly only dialed into Cerritos/Lakewood/Cypress area BBS's. Clockwork Orange, Eclectic Triage, Mr Ed's, Arrakis, etc. Was also on a couple Amiga BBS's - I owned an A1000+A1300 genlock for subtitle work back then, supplied tapes to Anime Expo in early days.
Before the web, I recall dialing into waffle BBS to access usenet. Sometime after that, telenet & talk/ytalk before irc.
Still friends with many people from that era 2-3 decades ago.
