Super Dimension Fortress
Super Dimension Fortress (SDF, also known as freeshell.org) is one of the oldest public access UNIX systems on the Internet.
It has been operational in some shape since the year 1987 as a non-profit organization. The name derives from the Japanese anime series The Super Dimension Fortress Macross, the original server having originally been a BBS for anime fans.
The system currently includes NetBSD servers for regular use (DEC Alphas) as well as a TWENEX system. As well as offering free Unix shell access to its users, SDF provides both web and Gopher hosting - making it one of very few servers still running the latter protocol.
