Oh god....I just flashed back to B drives...with REAL floppy discs that were...well...floppy...
My first taste was on Bulletin Boards, not like this one - I am talking OLD school bulletin Boards, where you dialed into with the blazing fast 9800 baud

Funny thing is I just googled the name of my BBS and sure enough it popped up.
AA Computer Masters, The River of Time, The River of Time BBS
(1993-1996)
I ran the River of Time after we merged with AA Computer masters to form The River of Time BBS, at one point we had over 54 CD's online at a time (back then we had SCSI drives that would hold 18 cds each).
Anyone got lucky to play games back then it was a blast, Scrabble and BRE/SRE - my fav was tradewars 2002 (before the script kids took over).
Anyhow I ran mine on Wildcat 3.0 or such, I think 4.0 was a windows version for Win 95, never got used to it plus the BBS was dying off to the internet.
Friend of my fathers ran his until 2000, not sure how you can have a BBS up that long but he did. I moved from the BBS more into lan centers back then, during my early days computers were bloody expensive. Think my dad paid $2900 for a 50mhz Gateway tower.
One good thing about cases back then - you can use em to stop a 18 wheeler, because man they were built tough, but heavy as hell too.
Edited: I just found the website for Tradewars 2002 - believe it or not over 500 people STILL play it each month, and its installed on 1800 servers.. amazing.
