The entire history is on the FreeHOF web site. Also there are downloadable copies of PCBoard, one of the great BBS platforms of all time. Anyone can create a dial-up BBS with this to see what they were like, so long as they have a DOS partition for it. I think MS DOS is also there to download, version 5.n or 6.n. Something you won't find at this site is games. FHOF never distributed games.
"No Flash, no Java, no goddam rollovers..." reads one page, which notes that in the mid-'90s they were picked as one of the world's 25 best BBSs by Boardwatch magazine.
