I remember printing out USENET posts on fan-fold perforated paper that had green and white stipes circa 1990. I think I got rid of all of them when I moved to Germany in 1999 and really pared down my possessions.
I should really look and see if I have anything interesting on my floppies that never made it to my hard disks. Unfortunately I think I have very little left from BBS forums. I definitely lost some things in hard disk crashes over the years with incomplete backups.
