A pair of HyperCard stacks from the National Science Foundation (NSF)
Network Service Center released in 1991 that explains the Internet to
new users. It's interesting to see the pre-web history of the
Internet, including poetry by Vint Cerf.

From the Readme file:
The Internet Tour was designed by the NSF Network Service Center as a
general introduction to the Internet for the new network user. It
contains information on the history of the Internet, network
etiquette, network applications, Internet resources, and a glossary of
networking terms.
