Vom Netzwerk:
he had discovered that the sound emitted by the toy whistle that came with the breakfast cereal was the same 2600 Hertz tone used by the phone network’s call-routing switches. It could fool the system into allowing a long-distance call to go through without extra charges. The article revealed that other tones that served to route calls could be found in an issue of the
Bell System Technical Journal
, which AT&T immediately began asking libraries to pull from their shelves.
    As soon as Jobs got the call from Wozniak that Sunday afternoon, he knew they would have to get their hands on the technical journal right away. “Woz picked me up a few minutes later, and we went to thelibrary at SLAC [the Stanford Linear Accelerator Center] to see if we could find it,” Jobs recounted. It was Sunday and the library was closed, but they knew how to get in through a door that was rarely locked. “I remember that we were furiously digging through the stacks, and it was Woz who finally found the journal with all the frequencies. It was like, holy shit, and we opened it and there it was. We kept saying to ourselves, ‘It’s real. Holy shit, it’s real.’ It was all laid out—the tones, the frequencies.”
    Wozniak went to Sunnyvale Electronics before it closed that evening and bought the parts to make an analog tone generator. Jobs had built a frequency counter when he was part of the HP Explorers Club, and they used it to calibrate the desired tones. With a dial, they could replicate and tape-record the sounds specified in the article. By midnight they were ready to test it. Unfortunately the oscillators they used were not quite stable enough to replicate the right chirps to fool the phone company. “We could see the instability using Steve’s frequency counter,” recalled Wozniak, “and we just couldn’t make it work. I had to leave for Berkeley the next morning, so we decided I would work on building a digital version once I got there.”
    No one had ever created a digital version of a Blue Box, but Woz was made for the challenge. Using diodes and transistors from Radio Shack, and with the help of a music student in his dorm who had perfect pitch, he got it built before Thanksgiving. “I have never designed a circuit I was prouder of,” he said. “I still think it was incredible.”
    One night Wozniak drove down from Berkeley to Jobs’s house to try it. They attempted to call Wozniak’s uncle in Los Angeles, but they got a wrong number. It didn’t matter; their device had worked. “Hi! We’re calling you for free! We’re calling you for free!” Wozniak shouted. The person on the other end was confused and annoyed. Jobs chimed in, “We’re calling from California! From California! With a Blue Box.” This probably baffled the man even more, since he was also in California.
    At first the Blue Box was used for fun and pranks. The most daring of these was when they called the Vatican and Wozniak pretended to be Henry Kissinger wanting to speak to the pope. “Ve are at de summit meeting in Moscow, and ve need to talk to de pope,”Woz intoned. He was told that it was 5:30 a.m. and the pope was sleeping. When he called back, he got a bishop who was supposed to serve as the translator. But they never actually got the pope on the line. “They realized that Woz wasn’t Henry Kissinger,” Jobs recalled. “We were at a public phone booth.”
    It was then that they reached an important milestone, one that would establish a pattern in their partnerships: Jobs came up with the idea that the Blue Box could be more than merely a hobby; they could build and sell them. “I got together the rest of the components, like the casing and power supply and keypads, and figured out how we could price it,” Jobs said, foreshadowing roles he would play when they founded Apple. The finished product was about the size of two decks of playing cards. The parts cost about $40, and Jobs decided they should sell it for $150.
    Following the lead of other phone phreaks such as Captain Crunch, they gave themselves handles. Wozniak became “Berkeley Blue,” Jobs was “Oaf Tobark.” They took the device to college dorms and gave demonstrations by attaching it to a phone and speaker. While the potential customers watched, they would call the Ritz in London or a dial-a-joke service in Australia. “We made a hundred or so Blue Boxes and sold almost all of them,” Jobs recalled.
    The fun and profits came to an end at a Sunnyvale pizza
