ZModem and HSLink (HSLink let you download and upload at the same time .. sorta). You also had the door games and 60 min limits and spending 3 days downloading Doom which came on three 1.4M disks.

Fire up Terminate, call my favorite BBS, log on, check messages, play some Trade Wars 2002. Those were the days. For a brief time, I had my own BBS and I was really proud when it became a FidoNet point.
