Below are goodies that could not be included in the book due to space constraints. Enjoy.
Chapter 17 of Exploding The Phone discusses Chic Eder (or, as he would have preferred it, "chic eder" — he apparently preferred his nickname in lower case) making a tape of John Draper intercepting a phone call in progress between the FBI's San Francisco Field Office and the Santa Cruz County Sheriff's office, and then handing this tape over to the FBI.
On a whim, I requested a copy of this tape from the FBI under the Freedom of Information Act. To my surprise, a year later they sent me an audio CD with the recording! You can listen to it below. (There are a four parts in the tape where the FBI blanked out the audio to protect somebody's name; you can see them in the visualization of the audio below.)
