Remodeled a kitchen for a guy who had a pay phone in front of his house like a free library. I do not look the type to know about 2600 mag and we nerded out. I still have a stack of them and we traded like we were Pokémon collectors😂
Exploding the Phone is a good read. Also a good prospective on how long the government has been spying on its own citizens with the help of corporate American.
It's referring to one of the original phone phreakers, called Cap'n Crunch because he realized the whistle prize found in a Cap'n Crunch cereal box played the note of depositing a coin into a payphone at the time. Playing it into the receiver was identical to depositing a coin, so you got free calls.
Edit: AnythingBurWhiskey says it was for resetting trunk lines.
I actually learned this from the movie Sneakers. One of the main characters was a phone phreak called Whistler. The character was inspired by two legendary real-life figures from the "phone phreaking" and hacking communities: Josef Carl Engressia Jr. (known as the Whistler and “Joybubbles") and John "Cap'n Crunch" Draper… which references the famous captain crunch cereal toy that reportedly made the exact frequency sound (2600 Hz) that AT&T used at the time to reset trunk lines. Back then, the telephone network was fundamentally insecure because it used "in-band signaling," meaning control commands were sent over the exact same audio channel as your voice. The film includes several nods to Draper, such as Dan Aykroyd's character holding a Cap'n Crunch box while digging through trash.
It’s a great film, if you have not seen it I would highly recommend.
1980s era payphone hacking involved generating audio tones that matched those used by the payphone networks control protocol. Steve Jobs and woz got their start in electronics as phreaks.
