This is the personal site of Evan Doorbell, who was one of the big phone phreaks in the 70's along with people like Mark Bernay. He recorded all the old telephone sounds and put them into different series where he explains how the old telephone system worked.

His "How Bell Became a Phreaker" tapes are where I first encountered the genre of "Hacker stories that start at the beginning." and it's still one of my favorites even though it's incomplete.[0]

Some notable tapes in this collection:

How Evan Doorbell became a Phone Phreak, parts 1 through 6 (Incomplete)

Phreaks from Esquire article on "052" conference, parts 1 and 2 (January, 1972) [The Secrets of The Little Blue Box esquire article[1]]

MF Boogie numbers one and two (Music made from phone tones, actually composed on an electronic organ during a conference call with NPR reporters. [2])
