I think that's meant to be a joke.

Gopher+ from the PISM book needs a minimum of System 7 and should work up to System 9 as it uses Users and Groups Control Panel for its user login information. I do not know about OSX.

Interesting. Some faculty and students in LIU (Long Island University) Computer Science dept. are recreating a gopher there since it's easier to use and maintain. Who knows. Maybe in a few years The Gopher Net Rises From The Dead!

Then with VRML and the 3D Internet, we can really get lost on the net!!!
