For example, if you want an analog circuit to generate a tone at a particular frequency, as you would for a blue box, you might need a resistor of 1000 ohms and a capacitor of 0.1 microfarads. This is because the components they are constructed with-resistors and capacitors and inductors and such-are themselves inexact. The problem with analog circuits is that they are imprecise. He thought more about the analog blue box that he and Jobs had tried to build. But he couldn't get his mind off of blue boxes and phone phreaking. Wozniak started classes at Berkeley the next day.
APPLE WHISTLE PHONE GENERATOR
In the end Wozniak concluded that the tone generator just wasn't good enough to make the telephone network dance to his tunes. They worked late into the night trying to figure out what was wrong. They were able to disconnect a call to 555-1212 with 2,600 Hz-they heard the kerchink! of the trunk-but their MF tone tape recordings didn't do anything.
Later that night they had managed to record pairs of tones on cassette tape, enough to make a blue box call.
That very day Wozniak and Jobs purchased analog tone generator kits from a local electronics store this was the Silicon Valley in 1971, after all, and such things were easily available. We now had the formula we needed! And definitely that article was for real." Jobs agrees: "We kept saying to ourselves, 'It's real. We couldn't stop talking all the way home. We kept saying things like 'Oh, shit!' and 'Wow, this thing is for real!' I was practically shaking, with goose bumps and everything. We both stared at the list, rushing with adrenaline. "I froze and grabbed Steve and nearly screamed in excitement that I'd found it. The two dug through the reference books and before long they struck pay dirt: an international telephone technical standard that listed the MF frequencies.
APPLE WHISTLE PHONE MANUAL
"If there was any place that had a phone manual that listed tone frequencies," he says, it would be SLAC. It had a great technical library, Wozniak says, and he had a long history of sneaking into it to look stuff up. SLAC was the atom smasher at Stanford University. Less than an hour later the duo were on their way to raid the library at the Stanford Linear Accelerator Center. He picked up the phone and called his friend Steve Jobs-then a seventeen-year-old senior in high school-to tell him about it. The twenty-year-old Wozniak put down the magazine.

As for Joe Engressia being able to whistle free calls? "I couldn't believe this was possible, but there it was and, wow, it just made my imagination run wild." The article even gave a few of the frequencies it used. "The idea of the Blue Box just amazed me," he says. Despite their fanciful nature and funny names, Wozniak remembers, "I could tell that the characters being described were really tech people, much like me, people who liked to design things just to see what was possible, and for no other reason, really." There was something about the whole thing that just rang true, despite how crazy it seemed.
Oddly enough, part of what made the article seem so real to him were the characters. And yet, he says, "I kept reading it over and over, and the more I read it, the more possible and real it sounded." They were anonymous technical people who went by fake names and lived all over the place," he recalls, how they were "outsmarting phone companies and setting up networks that nobody imagined existed." It seemed unbelievable. Rosenbaum's article "described a whole web of people who were doing this: the phone phreaks. Wozniak happened to pick up a copy of Esquire from his mother's kitchen table the day before starting classes at Berkeley in the fall of 1971. "It was the most amazing article I'd ever read!"
"You know how some articles just grab you from the first paragraph? Well, it was one of those articles," Steve Wozniak recalls. Like the flap of a butterfly's wings causing a hurricane half a world away, the ripples of unintended consequences from Ron Rosenbaum's " Secrets of the Little Blue Box" continued to spread.
