Lexington had an interesting mix of BBS systems. Transylvania University had a system that was open to non-students and had 3-4 incoming lines so you could do real time chat (!) unless of course someone improperly disconnected (dang call waiting) which would cause that line to hang for 30-60 minutes IIRC until it timed out.
Also another great BBS in Lexington was one running Pyroto Mountain where you're a wizard and there are different chat levels depending on your wizard level. Going "up" the mountain required answering trivia questions. To this day a lot of trivia still in my head is from those early Pyroto Mountain days.
I eventually moved to a 9600 baud (Hayes brand!) and then a 28.8k and then 56k modem. Zipping at a 1gig connection at home (always on - no call waiting!) is really quite amazing to experience in just 40-ish years.
