- The best prank I've seen with the Apple was played by Cap'n Crunch. John
- Draper, one of Apple's first employees, was responsible for designing a
- telephone board for us. Much more than a modem, the board could send
- touch-tone or pulse-dial data; it could also transmit any tones that were
- programmable down the line, listen for specific sounds, and a bunch of other
- things.
-
- At one point Draper was motivated to crack WATS extenders. A WATS extender
- is used when a company has incoming and outgoing free 800 lines. Company
- executives call in on the incoming 800 line and tap out a four-digit code,
- which gets them on their company's outgoing 800 line. They only system
- protection is the four-digit code.
-
- It would take a long time to dial 10,000 phone calls manually, searching for
- the extender code. But Draper had designed this new telephone board, and he
- knew a bunch of companies that had WATS extenders. He programmed the Apple to
- call the company on its 800 number, automatically get to the WATS extender,
- type out a four-digit code, and check to see if the attempt succeeded or
- failed. The Apple with the board would listen to all the tones on the phone
- line to determine when it was ringing, when it went to the WATS extender, and
- so on.
-
- It took about 10 seconds for the Apple to dial the call and try a new
- four-digit code. The Apple would restart and try again. And then try the next
- number. It was able to dial about 5,000 calls a night -- the average number of
- calls to crack a WATS extender. Draper cracked about 20 WATS exteders,
- averaging one a night.
-
- The city of Mountain View, California, where he lived at the time, keeps an
- index of how well the phone system is working. An average of 30% of all calls
- made from the city don't go through. The month Draper was cracking the WATS
- extenders, the index jumped to 80%! For that month Draper made more than 50%
- of the calls originating from Mountain View, California, whose population is
- 60,000.... <>
