Some Historical Documents
Below are some historical documents, many technical in nature,
that played a role in the development of phone phreaking.

article that introduced phreaking to the masses.
(Thanks to Number 6 for sending me a
much better scan of the article; the version
I posted originally is
here for posterity.)

newspaper article that appeared at about the same
time as the Esquire article.
