A friend of mine, Michael Pester, ran The Mouse Hole BBS in Des Moines, IA. He was running multiple lines, and I can't remember if he eventually got it up on the Internet or not - I was headed down the Internet/ISP path at the time. He was great though in letting me take a close look at all the software and how it operated. He's unfortunately passed away now, but he developed a lot of FidoNet and communications software for the Mac at the time.
