Ah the dial-up ISP days. As an young enterprising middle schooler 20+ years ago I started one with the help of my father. I remember stringing together a bunch of modems to a Postmaster and getting a rollover PRI line from the local telco. If my memory serves me it had 24 lines and would roll over if one was busy. We even made some of our own installation floppy disks and placed them at the local video rental store so people could self install. Fun times!
