Relatedly, http://telehack.com/ http://telehack.com/ is, to quote itself: a full multi-user simulation, including 25,000 hosts and BBS's from the early net, thousands of files from the era, a collection of adventure and IF games, a working BASIC interpreter with a library of programs to run, simulated historical users, and more. Pretty fun to play around with for a bit.
