My first BBS was an EBBS-64 (Commodore); I later upgraded to EBBS-128; then switched to a Macintosh running a port of WWIV (an early Pascal branch, I believe, pre-ANSI color); I also experimented with something called "Nova" on the Macintosh. Finally ended up running Wayne Bell's WWIV on a PC XT compat. I retired my BBS sometime in early 1990, at I believe version 3.10 of WWIV. During that time, I participated in a couple different WWIV networks.
Had plenty of doors on my PC WWIV, and TradeWars 2000 was one of them, though it wasn't networked in any way (I don't think that was an option at the time?) It was good, one of the best, but not my favorite.
After BBSes, I found a whole new way to waste time. Playing in the mud was the second best use for the Internet I had found. (Anonymous FTP was the first!)
I used to run a CNet-Amiga BBS. I built a KILLER Amiga just to run it.:-)
I used to play Tradewars as well. Yes those were the days
Ah... the good old days! I wrote a couple of doors that worked on PcBoard, RemoteAccess, and WWIV.
I never got into Mud... I was too busy figuring out how to write decent Cobol code on the DEC VAX at Cal Poly, Pomona. :-)
