Loading up Procom to dial your favorite boards in sequence, listening to the shhhhhh---hisss--bong bong when you got your 1200 baud connection, trying to get every game played or message answered before your 30-45 minutes ran out.

I had a second line installed just for dialing BBSs.

Then I started my own multi-line subscription BBS and just as it started turning a profit, browsers came out and it was game over for BBSs.
