Dudes... These four files contain the story, "Secrets of the Little Blue Box",

by Ron Rosenbaum.


-A story so incredible it may even make you feel sorry for the phone company-


Printed in the October 1971 issue of Esquire Magazine. If you happen to be in

a library and come across a collection of Esquire magazines, the October 1971

issue is the first issue printed in the smaller format. The story begins on

page 116 with a picture of a blue box.

The Blue Box Is Introduced: Its Qualities Are Remarked


I am in the expensively furnished living room of Al Gilbertson (His real name

has been changed.), the creator of the "blue box." Gilbertson is holding one of

his shiny black-and-silver "blue boxes" comfortably in the palm of his hand,

pointing out the thirteen little red push buttons sticking up from the console.

He is dancing his fingers over the buttons, tapping out discordant beeping

electronic jingles. He is trying to explain to me how his little blue box does

nothing less than place the entire telephone system of the world, satellites,

cables and all, at the service of the blue-box operator, free of charge.


"That's what it does. Essentially it gives you the power of a super operator.

You seize a tandem with this top button," he presses the top button with his

index finger and the blue box emits a high-pitched cheep, "and like that" --

cheep goes the blue box again -- "you control the phone company's long-distance

switching systems from your cute little Princes phone or any old pay phone.

And you've got anonymity. An operator has to operate from a definite location:

the phone company knows where she is and what she's doing. But with your

beeper box, once you hop onto a trunk, say from a Holiday Inn 800 (toll-free)

number, they don't know where you are, or where you're coming from, they don't

know how you slipped into their lines and popped up in that 800 number. They

don't even know anything illegal is going on. And you can obscure your origins

through as many levels as you like. You can call next door by way of White

Plains, then over to Liverpool by cable, and then back here by satellite. You

can call yourself from one pay phone all the way around the world to a pay

phone next to you. And you get your dime back too."


"And they can't trace the calls? They can't charge you?"

"Not if you do it the right way. But you'll find that the free-call thing

isn't really as exciting at first as the feeling of power you get from having

one of these babies in your hand. I've watched people when they first get hold

of one of these things and start using it, and discover they can make

connections, set up crisscross and zigzag switching patterns back and forth

across the world. They hardly talk to the people they finally reach. They say

hello and start thinking of what kind of call to make next. They go a little

crazy." He looks down at the neat little package in his palm. His fingers are

still dancing, tapping out beeper patterns.


"I think it's something to do with how small my models are. There are lots of

blue boxes around, but mine are the smallest and most sophisticated

electronically. I wish I could show you the prototype we made for our big

syndicate order."


He sighs. "We had this order for a thousand beeper boxes from a syndicate

front man in Las Vegas. They use them to place bets coast to coast, keep lines

open for hours, all of which can get expensive if you have to pay. The deal

was a thousand blue boxes for $300 apiece. Before then we retailed them for

$1500 apiece, but $300,000 in one lump was hard to turn down. We had a

manufacturing deal worked out in the Philippines. Everything ready to go.

Anyway, the model I had ready for limited mass production was small enough to

fit inside a flip-top Marlboro box. It had flush touch panels for a keyboard,

rather than these unsightly buttons, sticking out. Looked just like a tiny

portable radio. In fact, I had designed it with a tiny transistor receiver to

get one AM channel, so in case the law became suspicious the owner could switch

on the radio part, start snapping his fingers, and no one could tell anything

illegal was going on. I thought of everything for this model -- I had it lined

with a band of thermite which could be ignited by radio signal from a tiny

button transmitter on your belt, so it could be burned to ashes instantly in

case of a bust. It was beautiful. A beautiful little machine. You should

have seen the faces on these syndicate guys when they came back after trying it

out. They'd hold it in their palm like they never wanted to let it go, and

they'd say, 'I can't believe it. I can't believe it.' You probably won't

believe it until you try it."


The Blue Box Is Tested: Certain Connections Are Made


About eleven o'clock two nights later Fraser Lucey has a blue box in the palm

of his left hand and a phone in the palm of his right. He is standing inside a

phone booth next to an isolated shut-down motel off Highway 1. I am standing

outside the phone booth.


Fraser likes to show off his blue box for people. Until a few weeks ago when

Pacific Telephone made a few arrests in his city, Fraser Lucey liked to bring

his blue box (This particular blue box, like most blue boxes, is not blue.

Blue boxes have come to be called "blue boxes" either because 1) The first blue

box ever confiscated by phone-company security men happened to be blue, or 2)

To distinguish them from "black boxes." Black boxes are devices, usually a

resistor in series, which, when attached to home phones, allow all incoming

calls to be made without charge to one's caller.) to parties. It never failed:

a few cheeps from his device and Fraser became the center of attention at the

very hippest of gatherings, playing phone tricks and doing request numbers for

hours. He began to take orders for his manufacturer in Mexico. He became a



Fraser is cautious now about where he shows off his blue box. But he never

gets tired of playing with it. "It's like the first time every time," he tells



Fraser puts a dime in the slot. He listens for a tone and holds the receiver

up to my ear. I hear the tone. Fraser begins describing, with a certain

practiced air, what he does while he does it. "I'm dialing an 800 number now.

Any 800 number will do. It's toll free. Tonight I think I'll use the ----- (he

names a well-know rent-a-car company) 800 number. Listen, It's ringing. Here,

you hear it? Now watch." He places the blue box over the mouthpiece of the

phone so that the one silver and twelve black push buttons are facing up toward

me. He presses the silver button -- the one at the top -- and I hear that

high-pitched beep. "That's 2600 cycles per second to be exact," says Lucey.

"Now, quick. listen." He shoves the earpiece at me. The ringing has vanished.

The line gives a slight hiccough, there is a sharp buzz, and then nothing but

soft white noise.


"We're home free now," Lucey tells me, taking back the phone and applying the

blue box to its mouthpiece once again. "We're up on a tandem, into a

long-lines trunk. Once you're up on a tandem, you can send yourself anywhere

you want to go." He decides to check out London first. He chooses a certain

pay phone located in Waterloo Station. This particular pay phone is popular

with the phone-phreaks network because there are usually people walking by at

all hours who will pick it up and talk for a while.


He presses the lower left-hand corner button which is marked "KP" on the face

of the box. "That's Key Pulse. It tells the tandem we're ready to give it

instructions. First I'll punch out KP 182 START, which will slide us into the

overseas sender in White Plains." I hear a neat clunk-cheep. "I think we'll

head over to England by satellite. Cable is actually faster and the connection

is somewhat better, but I like going by satellite. So I just punch out KP Zero

44. The Zero is supposed to guarantee a satellite connection and 44 is the

country code for England. Okay... we're there. In Liverpool actually. Now

all I have to do is punch out the London area code which is 1, and dial up the

pay phone. Here, listen, I've got a ring now."


I hear the soft quick purr-purr of a London ring. Then someone picks up the



"Hello," says the London voice.


"Hello. Who's this?" Fraser asks.


"Hello. There's actually nobody here. I just picked this up while I was

passing by. This is a public phone. There's no one here to answer actually."


"Hello. Don't hang up. I'm calling from the United States."


"Oh. What is the purpose of the call? This is a public phone you know."


"Oh. You know. To check out, uh, to find out what's going on in London. How

is it there?"


"Its five o'clock in the morning. It's raining now."


"Oh. Who are you?"


The London passerby turns out to be an R.A.F. enlistee on his way back to the

base in Lincolnshire, with a terrible hangover after a thirty-six-hour pass.

He and Fraser talk about the rain. They agree that it's nicer when it's not

raining. They say good-bye and Fraser hangs up. His dime returns with a nice



"Isn't that far out," he says grinning at me. "London, like that."


Fraser squeezes the little blue box affectionately in his palm. "I told ya

this thing is for real. Listen, if you don't mind I'm gonna try this girl I

know in Paris. I usually give her a call around this time. It freaks her out.

This time I'll use the ------ (a different rent-a-car company) 800 number and

we'll go by overseas cable, 133; 33 is the country code for France, the 1 sends

you by cable. Okay, here we go.... Oh damn. Busy. Who could she be talking

to at this time?"


A state police car cruises slowly by the motel. The car does not stop, but

Fraser gets nervous. We hop back into his car and drive ten miles in the

opposite direction until we reach a Texaco station locked up for the night. We

pull up to a phone booth by the tire pump. Fraser dashes inside and tries the

Paris number. It is busy again.


"I don't understand who she could be talking to. The circuits may be busy.

It's too bad I haven't learned how to tap into lines overseas with this thing



Fraser begins to phreak around, as the phone phreaks say. He dials a leading

nationwide charge card's 800 number and punches out the tones that bring him

the time recording in Sydney, Australia. He beeps up the weather recording in

Rome, in Italian of course. He calls a friend in Boston and talks about a

certain over-the-counter stock they are into heavily. He finds the Paris

number busy again. He calls up "Dial a Disc" in London, and we listen to

Double Barrel by David and Ansil Collins, the number-one hit of the week in

London. He calls up a dealer of another sort and talks in code. He calls up

Joe Engressia, the original blind phone-phreak genius, and pays his respects.

There are other calls. Finally Fraser gets through to his young lady in



They both agree the circuits must have been busy, and criticize the Paris

telephone system. At two-thirty in the morning Fraser hangs up, pockets his

dime, and drives off, steering with one hand, holding what he calls his "lovely

little blue box" in the other.


You Can Call Long Distance For Less Than You Think


"You see, a few years ago the phone company made one big mistake," Gilbertson

explains two days later in his apartment. "They were careless enough to let

some technical journal publish the actual frequencies used to create all their

multi-frequency tones. Just a theoretical article some Bell Telephone

Laboratories engineer was doing about switching theory, and he listed the tones

in passing. At ----- (a well-known technical school) I had been fooling around

with phones for several years before I came across a copy of the journal in the

engineering library. I ran back to the lab and it took maybe twelve hours from

the time I saw that article to put together the first working blue box. It was

bigger and clumsier than this little baby, but it worked."


It's all there on public record in that technical journal written mainly by

Bell Lab people for other telephone engineers. Or at least it was public.

"Just try and get a copy of that issue at some engineering-school library now.

Bell has had them all red-tagged and withdrawn from circulation," Gilbertson

tells me.


"But it's too late. It's all public now. And once they became public the

technology needed to create your own beeper device is within the range of any

twelve-year-old kid, any twelve-year-old blind kid as a matter of fact. And he

can do it in less than the twelve hours it took us. Blind kids do it all the

time. They can't build anything as precise and compact as my beeper box, but

theirs can do anything mine can do."




"Okay. About twenty years ago A.T.&T. made a multi-billion-dollar decision to

operate its entire long-distance switching system on twelve electronically

generated combinations of twelve master tones. Those are the tones you

sometimes hear in the background after you've dialed a long-distance number.

They decided to use some very simple tones -- the tone for each number is just

two fixed single-frequency tones played simultaneously to create a certain beat

frequency. Like 1300 cycles per second and 900 cycles per second played

together give you the tone for digit 5. Now, what some of these phone phreaks

have done is get themselves access to an electric organ. Any cheap family

home-entertainment organ. Since the frequencies are public knowledge now --

one blind phone phreak has even had them recorded in one of the talking books

for the blind -- they just have to find the musical notes on the organ which

correspond to the phone tones. Then they tape them. For instance, to get Ma

Bell's tone for the number 1, you press down organ keys F~5 and A~5 (900 and

700 cycles per second) at the same time. To produce the tone for 2 it's F~5

and C~6 (1100 and 700 c.p.s). The phone phreaks circulate the whole list of

notes so there's no trial and error anymore."


He shows me a list of the rest of the phone numbers and the two electric organ

keys that produce them.


"Actually, you have to record these notes at 3 3/4 inches-per-second tape speed

and double it to 7 1/2 inches-per-second when you play them back, to get the

proper tones," he adds.


"So once you have all the tones recorded, how do you plug them into the phone



"Well, they take their organ and their cassette recorder, and start banging out

entire phone numbers in tones on the organ, including country codes, routing

instructions, 'KP' and 'Start' tones. Or, if they don't have an organ, someone

in the phone-phreak network sends them a cassette with all the tones recorded,

with a voice saying 'Number one,' then you have the tone, 'Number two,' then

the tone and so on. So with two cassette recorders they can put together a

series of phone numbers by switching back and forth from number to number. Any

idiot in the country with a cheap cassette recorder can make all the free calls

he wants."


"You mean you just hold the cassette recorder up the mouthpiece and switch in a

series of beeps you've recorded? The phone thinks that anything that makes

these tones must be its own equipment?"


"Right. As long as you get the frequency within thirty cycles per second of

the phone company's tones, the phone equipment thinks it hears its own voice

talking to it. The original granddaddy phone phreak was this blind kid with

perfect pitch, Joe Engressia, who used to whistle into the phone. An operator

could tell the difference between his whistle and the phone company's

electronic tone generator, but the phone company's switching circuit can't tell

them apart. The bigger the phone company gets and the further away from human

operators it gets, the more vulnerable it becomes to all sorts of phone



A Guide for the Perplexed


"But wait a minute," I stop Gilbertson. "If everything you do sounds like

phone-company equipment, why doesn't the phone company charge you for the call

the way it charges its own equipment?"


"Okay. That's where the 2600-cycle tone comes in. I better start from the



The beginning he describes for me is a vision of the phone system of the

continent as thousands of webs, of long-line trunks radiating from each of the

hundreds of toll switching offices to the other toll switching offices. Each

toll switching office is a hive compacted of thousands of long-distance tandems

constantly whistling and beeping to tandems in far-off toll switching offices.


The tandem is the key to the whole system. Each tandem is a line with some

relays with the capability of signalling any other tandem in any other toll

switching office on the continent, either directly one-to-one or by programming

a roundabout route through several other tandems if all the direct routes are

busy. For instance, if you want to call from New York to Los Angeles and

traffic is heavy on all direct trunks between the two cities, your tandem in

New York is programmed to try the next best route, which may send you down to a

tandem in New Orleans, then up to San Francisco, or down to a New Orleans

tandem, back to an Atlanta tandem, over to an Albuquerque tandem and finally up

to Los Angeles.


When a tandem is not being used, when it's sitting there waiting for someone to

make a long-distance call, it whistles. One side of the tandem, the side

"facing" your home phone, whistles at 2600 cycles per second toward all the

home phones serviced by the exchange, telling them it is at their service,

should they be interested in making a long-distance call. The other side of

the tandem is whistling 2600 c.p.s. into one or more long-distance trunk lines,

telling the rest of the phone system that it is neither sending nor receiving a

call through that trunk at the moment, that it has no use for that trunk at the



"When you dial a long-distance number the first thing that happens is that you

are hooked into a tandem. A register comes up to the side of the tandem facing

away from you and presents that side with the number you dialed. This sending

side of the tandem stops whistling 2600 into its trunk line. When a tandem

stops the 2600 tone it has been sending through a trunk, the trunk is said to

be "seized," and is now ready to carry the number you have dialed -- converted

into multi-frequency beep tones -- to a tandem in the area code and central

office you want.


Now when a blue-box operator wants to make a call from New Orleans to New York

he starts by dialing the 800 number of a company which might happen to have its

headquarters in Los Angeles. The sending side of the New Orleans tandem stops

sending 2600 out over the trunk to the central office in Los Angeles, thereby

seizing the trunk. Your New Orleans tandem begins sending beep tones to a

tandem it has discovered idly whistling 2600 cycles in Los Angeles. The

receiving end of that L.A. tandem is seized, stops whistling 2600, listens to

the beep tones which tell it which L.A. phone to ring, and starts ringing the

800 number. Meanwhile a mark made in the New Orleans office accounting tape

notes that a call from your New Orleans phone to the 800 number in L.A. has

been initiated and gives the call a code number. Everything is routine so far.


But then the phone phreak presses his blue box to the mouthpiece and pushes the

2600-cycle button, sending 2600 out from the New Orleans tandem to the L.A.

tandem. The L.A. tandem notices 2600 cycles are coming over the line again and

assumes that New Orleans has hung up because the trunk is whistling as if idle.

The L.A. tandem immediately ceases ringing the L.A. 800 number. But as soon as

the phreak takes his finger off the 2600 button, the L.A. tandem assumes the

trunk is once again being used because the 2600 is gone, so it listens for a

new series of digit tones - to find out where it must send the call.


Thus the blue-box operator in New Orleans now is in touch with a tandem in L.A.

which is waiting like an obedient genie to be told what to do next. The

blue-box owner then beeps out the ten digits of the New York number which tell

the L.A. tandem to relay a call to New York City. Which it promptly does. As

soon as your party picks up the phone in New York, the side of the New Orleans

tandem facing you stops sending 2600 cycles to you and stars carrying his voice

to you by way of the L.A. tandem. A notation is made on the accounting tape

that the connection has been made on the 800 call which had been initiated and

noted earlier. When you stop talking to New York a notation is made that the

800 call has ended.


At three the next morning, when the phone company's accounting computer starts

reading back over the master accounting tape for the past day, it records that

a call of a certain length of time was made from your New Orleans home to an

L.A. 800 number and, of course, the accounting computer has been trained to

ignore those toll-free 800 calls when compiling your monthly bill.


"All they can prove is that you made an 800 toll-free call," Gilbertson the

inventor concludes. "Of course, if you're foolish enough to talk for two hours

on an 800 call, and they've installed one of their special anti-fraud computer

programs to watch out for such things, they may spot you and ask why you took

two hours talking to Army Recruiting's 800 number when you're 4-F.


But if you do it from a pay phone, they may discover something peculiar the

next day -- if they've got a blue-box hunting program in their computer -- but

you'll be a long time gone from the pay phone by then. Using a pay phone is

almost guaranteed safe."


"What about the recent series of blue-box arrests all across the country -- New

York, Cleveland, and so on?" I asked. "How were they caught so easily?"


"From what I can tell, they made one big mistake: they were seizing trunks

using an area code plus 555-1212 instead of an 800 number. Using 555 is easy to

detect because when you send multi-frequency beep tones of 555 you get a charge

for it on your tape and the accounting computer knows there's something wrong

when it tries to bill you for a two-hour call to Akron, Ohio, information, and

it drops a trouble card which goes right into the hands of the security agent

if they're looking for blue-box user.


"Whoever sold those guys their blue boxes didn't tell them how to use them

properly, which is fairly irresponsible. And they were fairly stupid to use

them at home all the time.


"But what those arrests really mean is than an awful lot of blue boxes are

flooding into the country and that people are finding them so easy to make that

they know how to make them before they know how to use them. Ma Bell is in



And if a blue-box operator or a cassette-recorder phone phreak sticks to pay

phones and 800 numbers, the phone company can't stop them?


"Not unless they change their entire nationwide long-lines technology, which

will take them a few billion dollars and twenty years. Right now they can't do

a thing. They're screwed."


Captain Crunch Demonstrates His Famous Unit


There is an underground telephone network in this country. Gilbertson

discovered it the very day news of his activities hit the papers. That evening

his phone began ringing. Phone phreaks from Seattle, from Florida, from New

York, from San Jose, and from Los Angeles began calling him and telling him

about the phone-phreak network. He'd get a call from a phone phreak who'd say

nothing but, "Hang up and call this number."


When he dialed the number he'd find himself tied into a conference of a dozen

phone phreaks arranged through a quirky switching station in British Columbia.

They identified themselves as phone phreaks, they demonstrated their homemade

blue boxes which they called "M-Fers" (for "multi-frequency," among other

things) for him, they talked shop about phone-phreak devices. They let him in

on their secrets on the theory that if the phone company was after him he must

be trustworthy. And, Gilbertson recalls, they stunned him with their technical



I ask him how to get in touch with the phone-phreak network. He digs around

through a file of old schematics and comes up with about a dozen numbers in

three widely separated area codes.


"Those are the centers," he tells me. Alongside some of the numbers he writes

in first names or nicknames: names like Captain Crunch, Dr. No, Frank Carson

(also a code word for a free call), Marty Freeman (code word for M-F device),

Peter Perpendicular Pimple, Alefnull, and The Cheshire Cat. He makes checks

alongside the names of those among these top twelve who are blind. There are

five checks.


I ask him who this Captain Crunch person is.


"Oh. The Captain. He's probably the most legendary phone phreak. He calls

himself Captain Crunch after the notorious Cap'n Crunch 2600 whistle."

(Several years ago, Gilbertson explains, the makers of Cap'n Crunch breakfast

cereal offered a toy-whistle prize in every box as a treat for the Cap'n Crunch

set. Somehow a phone phreak discovered that the toy whistle just happened to

produce a perfect 2600-cycle tone. When the man who calls himself Captain

Crunch was transferred overseas to England with his Air Force unit, he would

receive scores of calls from his friends and "mute" them -- make them free of

charge to them -- by blowing his Cap'n Crunch whistle into his end.)

"Captain Crunch is one of the older phone phreaks," Gilbertson tells me. "He's

an engineer who once got in a little trouble for fooling around with the phone,

but he can't stop. Well, they guy drives across country in a Volkswagen van

with an entire switchboard and a computerized super-sophisticated M-F-er in the

back. He'll pull up to a phone booth on a lonely highway somewhere, snake a

cable out of his bus, hook it onto the phone and sit for hours, days sometimes,

sending calls zipping back and forth across the country, all over the



Back at my motel, I dialed the number he gave me for "Captain Crunch" and asked

for G---- T-----, his real name, or at least the name he uses when he's not

dashing into a phone booth beeping out M-F tones faster than a speeding bullet

and zipping phantomlike through the phone company's long-distance lines.


When G---- T----- answered the phone and I told him I was preparing a story for

Esquire about phone phreaks, he became very indignant.


"I don't do that. I don't do that anymore at all. And if I do it, I do it for

one reason and one reason only. I'm learning about a system. The phone

company is a System. A computer is a System, do you understand? If I do what

I do, it is only to explore a system. Computers, systems, that's my bag. The

phone company is nothing but a computer."


A tone of tightly restrained excitement enters the Captain's voice when he

starts talking about systems. He begins to pronounce each syllable with the

hushed deliberation of an obscene caller.


"Ma Bell is a system I want to explore. It's a beautiful system, you know, but

Ma Bell screwed up. It's terrible because Ma Bell is such a beautiful system,

but she screwed up. I learned how she screwed up from a couple of blind kids

who wanted me to build a device. A certain device. They said it could make

free calls. I wasn't interested in free calls. But when these blind kids told

me I could make calls into a computer, my eyes lit up. I wanted to learn about

computers. I wanted to learn about Ma Bell's computers. So I build the little

device, but I built it wrong and Ma Bell found out. Ma Bell can detect things

like that. Ma Bell knows. So I'm strictly rid of it now. I don't do it.

Except for learning purposes." He pauses. "So you want to write an article.

Are you paying for this call? Hang up and call this number." He gives me a

number in a area code a thousand miles away of his own. I dial the number.


"Hello again. This is Captain Crunch. You are speaking to me on a toll-free

loop-around in Portland, Oregon. Do you know what a toll-free loop around is?

I'll tell you.


He explains to me that almost every exchange in the country has open test

numbers which allow other exchanges to test their connections with it. Most of

these numbers occur in consecutive pairs, such as 302 956-0041 and 302

956-0042. Well, certain phone phreaks discovered that if two people from

anywhere in the country dial the two consecutive numbers they can talk together

just as if one had called the other's number, with no charge to either of them,

of course.


"Now our voice is looping around in a 4A switching machine up there in Canada,

zipping back down to me," the Captain tells me. "My voice is looping around up

there and back down to you. And it can't ever cost anyone money. The phone

phreaks and I have compiled a list of many many of these numbers. You would be

surprised if you saw the list. I could show it to you. But I won't. I'm out

of that now. I'm not out to screw Ma Bell. I know better. If I do anything

it's for the pure knowledge of the System. You can learn to do fantastic

things. Have you ever heard eight tandems stacked up? Do you know the sound

of tandems stacking and unstacking? Give me your phone number. Okay. Hang up

now and wait a minute."


Slightly less than a minute later the phone rang and the Captain was on the

line, his voice sounding far more excited, almost aroused.


"I wanted to show you what it's like to stack up tandems. To stack up

tandems." (Whenever the Captain says "stack up" it sounds as if he is licking

his lips.)


"How do you like the connection you're on now?" the Captain asks me. "It's a

raw tandem. A raw tandem. Ain't nothin' up to it but a tandem. Now I'm going

to show you what it's like to stack up. Blow off. Land in a far away place.

To stack that tandem up, whip back and forth across the country a few times,

then shoot on up to Moscow.


"Listen," Captain Crunch continues. "Listen. I've got line tie on my

switchboard here, and I'm gonna let you hear me stack and unstack tandems.

Listen to this. It's gonna blow your mind."


First I hear a super rapid-fire pulsing of the flutelike phone tones, then a

pause, then another popping burst of tones, then another, then another. Each

burst is followed by a beep-kachink sound.


"We have now stacked up four tandems," said Captain Crunch, sounding somewhat

remote. "That's four tandems stacked up. Do you know what that means? That

means I'm whipping back and forth, back and forth twice, across the country,

before coming to you. I've been known to stack up twenty tandems at a time.

Now, just like I said, I'm going to shoot up to Moscow."


There is a new, longer series of beeper pulses over the line, a brief silence,

then a ring.


"Hello," answers a far-off voice.


"Hello. Is this the American Embassy Moscow?"


"Yes, sir. Who is this calling?" says the voice.


"Yes. This is test board here in New York. We're calling to check out the

circuits, see what kind of lines you've got. Everything okay there in





"Well, yes, how are things there?"


"Oh. Well, everything okay, I guess."


"Okay. Thank you."


They hang up, leaving a confused series of beep-kachink sounds hanging in

mid-ether in the wake of the call before dissolving away.


The Captain is pleased. "You believe me now, don't you? Do you know what I'd

like to do? I'd just like to call up your editor at Esquire and show him just

what it sounds like to stack and unstack tandems. I'll give him a show that

will blow his mind. What's his number?


I ask the Captain what kind of device he was using to accomplish all his feats.

The Captain is pleased at the question.


"You could tell it was special, couldn't you?" Ten pulses per second. That's

faster than the phone company's equipment. Believe me, this unit is the most

famous unit in the country. There is no other unit like it. Believe me."


"Yes, I've heard about it. Some other phone phreaks have told me about it."


"They have been referring to my, ahem, unit? What is it they said? Just out of

curiosity, did they tell you it was a highly sophisticated computer-operated

unit, with acoustical coupling for receiving outputs and a switch-board with

multiple-line-tie capability? Did they tell you that the frequency tolerance

is guaranteed to be not more than .05 percent? The amplitude tolerance less

than .01 decibel? Those pulses you heard were perfect. They just come faster

than the phone company. Those were high-precision op-amps. Op-amps are

instrumentation amplifiers designed for ultra-stable amplification, super-low

distortion and accurate frequency response. Did they tell you it can operate

in temperatures from -55 degrees C to +125 degrees C?"


I admit that they did not tell me all that.


"I built it myself," the Captain goes on. "If you were to go out and buy the

components from an industrial wholesaler it would cost you at least $1500. I

once worked for a semiconductor company and all this didn't cost me a cent. Do

you know what I mean? Did they tell you about how I put a call completely

around the world? I'll tell you how I did it. I M-Fed Tokyo inward, who

connected me to India, India connected me to Greece, Greece connected me to

Pretoria, South Africa, South Africa connected me to South America, I went from

South America to London, I had a London operator connect me to a New York

operator, I had New York connect me to a California operator who rang the phone

next to me. Needless to say I had to shout to hear myself. But the echo was

far out. Fantastic. Delayed. It was delayed twenty seconds, but I could hear

myself talk to myself."


"You mean you were speaking into the mouthpiece of one phone sending your voice

around the world into your ear through a phone on the other side of your head?"

I asked the Captain. I had a vision of something vaguely autoerotic going on,

in a complex electronic way.


"That's right," said the Captain. "I've also sent my voice around the world

one way, going east on one phone, and going west on the other, going through

cable one way, satellite the other, coming back together at the same time,

ringing the two phones simultaneously and picking them up and whipping my

voice both ways around the world back to me. Wow. That was a mind blower."


"You mean you sit there with both phones on your ear and talk to yourself

around the world," I said incredulously.


"Yeah. Um hum. That's what I do. I connect the phone together and sit there

and talk."


"What do you say? What do you say to yourself when you're connected?"


"Oh, you know. Hello test one two three," he says in a low-pitched voice.


"Hello test one two three," he replied to himself in a high-pitched voice.


"Hello test one two three," he repeats again, low-pitched.


"Hello test one two three," he replies, high-pitched.


"I sometimes do this: Hello Hello Hello Hello, Hello, hello," he trails off and

breaks into laughter.


Why Captain Crunch Hardly Ever Taps Phones Anymore


Using internal phone-company codes, phone phreaks have learned a simple method

for tapping phones. Phone-company operators have in front of them a board that

holds verification jacks. It allows them to plug into conversations in case of

emergency, to listen in to a line to determine if the line is busy or the

circuits are busy. Phone phreaks have learned to beep out the codes which lead

them to a verification operator, tell the verification operator they are

switchmen from some other area code testing out verification trunks. Once the

operator hooks them into the verification trunk, they disappear into the board

for all practical purposes, slip unnoticed into any one of the 10,000 to

100,000 numbers in that central office without the verification operator

knowing what they're doing, and of course without the two parties to the

connection knowing there is a phantom listener present on their line.


Toward the end of my hour-long first conversation with him, I asked the Captain

if he ever tapped phones.


"Oh no. I don't do that. I don't think it's right," he told me firmly. "I

have the power to do it but I don't... Well one time, just one time, I have to

admit that I did. There was this girl, Linda, and I wanted to find out... you

know. I tried to call her up for a date. I had a date with her the last

weekend and I thought she liked me. I called her up, man, and her line was

busy, and I kept calling and it was still busy. Well, I had just learned about

this system of jumping into lines and I said to myself, 'Hmmm. Why not just

see if it works. It'll surprise her if all of a sudden I should pop up on her

line. It'll impress her, if anything.' So I went ahead and did it. I M-Fed

into the line. My M-F-er is powerful enough when patched directly into the

mouthpiece to trigger a verification trunk without using an operator the way

the other phone phreaks have to.


"I slipped into the line and there she was talking to another boyfriend.

Making sweet talk to him. I didn't make a sound because I was so disgusted.

So I waited there for her to hang up, listening to her making sweet talk to the

other guy. You know. So as soon as she hung up I instantly M-F-ed her up and

all I said was, 'Linda, we're through.' And I hung up. And it blew her head

off. She couldn't figure out what the hell happened.


"But that was the only time. I did it thinking I would surprise her, impress

her. Those were all my intentions were, and well, it really kind of hurt me

pretty badly, and... and ever since then I don't go into verification trunks."


Moments later my first conversation with the Captain comes to a close.


"Listen," he says, his spirits somewhat cheered, "listen. What you are going

to hear when I hang up is the sound of tandems unstacking. Layer after layer of

tandems unstacking until there's nothing left of the stack, until it melts away

into nothing. Cheep, cheep, cheep, cheep," he concludes, his voice descending

to a whisper with each cheep.


He hangs up. The phone suddenly goes into four spasms: kachink cheep. Kachink

cheep kachink cheep kachink cheep, and the complex connection has wiped itself

out like the Cheshire cat's smile.


The MF Boogie Blues


The next number I choose from the select list of phone-phreak alumni, prepared

for me by the blue-box inventor, is a Memphis number. It is the number of Joe

Engressia, the first and still perhaps the most accomplished blind phone



Three years ago Engressia was a nine-day wonder in newspapers and magazines all

over America because he had been discovered whistling free long-distance

connections for fellow students at the University of South Florida. Engressia

was born with perfect pitch: he could whistle phone tones better than the

phone-company's equipment.


Engressia might have gone on whistling in the dark for a few friends for the

rest of his life if the phone company hadn't decided to expose him. He was

warned, disciplined by the college, and the whole case became public. In the

months following media reports of his talent, Engressia began receiving strange

calls. There were calls from a group of kids in Los Angeles who could do some

very strange things with the quirky General Telephone and Electronics circuitry

in L.A. suburbs. There were calls from a group of mostly blind kids in ----,

California, who had been doing some interesting experiments with Cap'n Crunch

whistles and test loops. There was a group in Seattle, a group in Cambridge,

Massachusetts, a few from New York, a few scattered across the country. Some

of them had already equipped themselves with cassette and electronic M-F

devices. For some of these groups, it was the first time they knew of the



The exposure of Engressia was the catalyst that linked the separate

phone-phreak centers together. They all called Engressia. They talked to him

about what he was doing and what they were doing. And then he told them -- the

scattered regional centers and lonely independent phone phreakers -- about each

other, gave them each other's numbers to call, and within a year the scattered

phone-phreak centers had grown into a nationwide underground.


Joe Engressia is only twenty-two years old now, but along the phone-phreak

network he is "the old man," accorded by phone phreaks something of the

reverence the phone company bestows on Alexander Graham Bell. He seldom needs

to make calls anymore. The phone phreaks all call him and let him know what

new tricks, new codes, new techniques they have learned. Every night he sits

like a sightless spider in his little apartment receiving messages from every

tendril of his web. It is almost a point of pride with Joe that they call



But when I reached him in his Memphis apartment that night, Joe Engressia was

lonely, jumpy and upset.


"God, I'm glad somebody called. I don't know why tonight of all nights I don't

get any calls. This guy around here got drunk again tonight and propositioned

me again. I keep telling him we'll never see eye to eye on this subject, if

you know what I mean. I try to make light of it, you know, but he doesn't get

it. I can head him out there getting drunker and I don't know what he'll do

next. It's just that I'm really all alone here, just moved to Memphis, it's

the first time I'm living on my own, and I'd hate for it to all collapse now.

But I won't go to bed with him. I'm just not very interested in sex and even

if I can't see him I know he's ugly.


"Did you hear that? That's him banging a bottle against the wall outside.

He's nice. Well forget about it. You're doing a story on phone phreaks?

Listen to this. It's the MF Boogie Blues.


Sure enough, a jumpy version of Muskrat Ramble boogies its way over the line,

each note one of those long-distance phone tones. The music stops. A huge

roaring voice blasts the phone off my ear: "AND THE QUESTION IS..." roars the



The roar ceases. A high-pitched operator-type voice replaces it. "This is

Southern Braille Tel. & Tel. Have tone, will phone."


This is succeeded by a quick series of M-F tones, a swift "kachink" and a deep

reassuring voice: "If you need home care, call the visiting-nurses association.

First National time in Honolulu is 4:32 p.m."


Joe back in his Joe voice again: "Are we seeing eye to eye? 'Si, si,' said the

blind Mexican. Ahem. Yes. Would you like to know the weather in Tokyo?"


This swift manic sequence of phone-phreak vaudeville stunts and blind-boy jokes

manages to keep Joe's mind off his tormentor only as long as it lasts.


"The reason I'm in Memphis, the reason I have to depend on that homosexual guy,

is that this is the first time I've been able to live on my own and make phone

trips on my own. I've been banned from all central offices around home in

Florida, they knew me too well, and at the University some of my fellow

scholars were always harassing me because I was on the dorm pay phone all the

time and making fun of me because of my fat ass, which of course I do have,

it's my physical fatness program, but I don't like to hear it every day, and if

I can't phone trip and I can't phone phreak, I can't imagine what I'd do, I've

been devoting three quarters of my life to it.


"I moved to Memphis because I wanted to be on my own as well as because it has

a Number 5 crossbar switching system and some interesting little independent

phone-company districts nearby and so far they don't seem to know who I am so I

can go on phone tripping, and for me phone tripping is just as important as

phone phreaking."


Phone tripping, Joe explains, begins with calling up a central-office switch

room. He tells the switchman in a polite earnest voice that he's a blind

college student interested in telephones, and could he perhaps have a guided

tour of the switching station? Each step of the tour Joe likes to touch and

feel relays, caress switching circuits, switchboards, crossbar arrangements.


So when Joe Engressia phone phreaks he feels his way through the circuitry of

the country garden of forking paths, he feels switches shift, relays shunt,

crossbars swivel, tandems engage and disengage even as he hears -- with perfect

pitch -- his M-F pulses make the entire Bell system dance to his tune.


Just one month ago Joe took all his savings out of his bank and left home, over

the emotional protests of his mother. "I ran away from home almost," he likes

to say. Joe found a small apartment house on Union Avenue and began making

phone trips. He'd take a bus a hundred miles south in Mississippi to see some

old-fashioned Bell equipment still in use in several states, which had been

puzzling. He'd take a bus three hundred miles to Charlotte, North Carolina, to

look at some brand-new experimental equipment. He hired a taxi to drive him

twelve miles to a suburb to tour the office of a small phone company with some

interesting idiosyncrasies in its routing system. He was having the time of

his life, he said, the most freedom and pleasure he had known.


In that month he had done very little long-distance phone phreaking from his

own phone. He had begun to apply for a job with the phone company, he told me,

and he wanted to stay away from anything illegal.


"Any kind of job will do, anything as menial as the most lowly operator.

That's probably all they'd give me because I'm blind. Even though I probably

know more than most switchmen. But that's okay. I want to work for Ma Bell.

I don't hate Ma Bell the way Gilbertson and some phone phreaks do. I don't

want to screw Ma Bell. With me it's the pleasure of pure knowledge. There's

something beautiful about the system when you know it intimately the way I do.

But I don't know how much they know about me here. I have a very intuitive

feel for the condition of the line I'm on, and I think they're monitoring me

off and on lately, but I haven't been doing much illegal. I have to make a few

calls to switchmen once in a while which aren't strictly legal, and once I took

an acid trip and was having these auditory hallucinations as if I were trapped

and these planes were dive-bombing me, and all of sudden I had to phone phreak

out of there. For some reason I had to call Kansas City, but that's all."


A Warning Is Delivered


At this point -- one o'clock in my time zone -- a loud knock on my motel-room

door interrupts our conversation. Outside the door I find a uniformed security

guard who informs me that there has been an "emergency phone call" for me while

I have been on the line and that the front desk has sent him up to let me



Two seconds after I say good-bye to Joe and hang up, the phone rings.


"Who were you talking to?" the agitated voice demands. The voice belongs to

Captain Crunch. "I called because I decided to warn you of something. I

decided to warn you to be careful. I don't want this information you get to

get to the radical underground. I don't want it to get into the wrong hands.

What would you say if I told you it's possible for three phone phreaks to

saturate the phone system of the nation. Saturate it. Busy it out. All of

it. I know how to do this. I'm not gonna tell. A friend of mine has already

saturated the trunks between Seattle and New York. He did it with a

computerized M-F-er hitched into a special Manitoba exchange. But there are

other, easier ways to do it."


Just three people? I ask. How is that possible?


"Have you ever heard of the long-lines guard frequency? Do you know about

stacking tandems with 17 and 2600? Well, I'd advise you to find out about it.

I'm not gonna tell you. But whatever you do, don't let this get into the hands

of the radical underground."


(Later Gilbertson, the inventor, confessed that while he had always been

skeptical about the Captain's claim of the sabotage potential of trunk-tying

phone phreaks, he had recently heard certain demonstrations which convinced him

the Captain was not speaking idly. "I think it might take more than three

people, depending on how many machines like Captain Crunch's were available.

But even though the Captain sounds a little weird, he generally turns out to

know what he's talking about.")


"You know," Captain Crunch continues in his admonitory tone, "you know the

younger phone phreaks call Moscow all the time. Suppose everybody were to call

Moscow. I'm no right-winger. But I value my life. I don't want the Commies

coming over and dropping a bomb on my head. That's why I say you've got to be

careful about who gets this information."


The Captain suddenly shifts into a diatribe against those phone phreaks who

don't like the phone company.


"They don't understand, but Ma Bell knows everything they do. Ma Bell knows.

Listen, is this line hot? I just heard someone tap in. I'm not paranoid, but

I can detect things like that. Well, even if it is, they know that I know that

they know that I have a bulk eraser. I'm very clean." The Captain pauses,

evidently torn between wanting to prove to the phone-company monitors that he

does nothing illegal, and the desire to impress Ma Bell with his prowess. "Ma

Bell knows how good I am. And I am quite good. I can detect reversals, tandem

switching, everything that goes on on a line. I have relative pitch now. Do

you know what that means? My ears are a $20,000 piece of equipment. With my

ears I can detect things they can't hear with their equipment. I've had

employment problems. I've lost jobs. But I want to show Ma Bell how good I

am. I don't want to screw her, I want to work for her. I want to do good for

her. I want to help her get rid of her flaws and become perfect. That's my

number-one goal in life now." The Captain concludes his warnings and tells me

he has to be going. "I've got a little action lined up for tonight," he

explains and hangs up.


Before I hang up for the night, I call Joe Engressia back. He reports that his

tormentor has finally gone to sleep -- "He's not blind drunk, that's the way I

get, ahem, yes; but you might say he's in a drunken stupor." I make a date to

visit Joe in Memphis in two days.


A Phone Phreak Call Takes Care of Business


The next morning I attend a gathering of four phone phreaks in ----- (a

California suburb). The gathering takes place in a comfortable split-level

home in an upper-middle-class subdivision. Heaped on the kitchen table are the

portable cassette recorders, M-F cassettes, phone patches, and line ties of the

four phone phreaks present. On the kitchen counter next to the telephone is a

shoe-box-size blue box with thirteen large toggle switches for the tones. The

parents of the host phone phreak, Ralph, who is blind, stay in the living room

with their sighted children. They are not sure exactly what Ralph and his

friends do with the phone or if it's strictly legal, but he is blind and they

are pleased he has a hobby which keeps him busy.


The group has been working at reestablishing the historic "2111" conference,

reopening some toll-free loops, and trying to discover the dimensions of what

seem to be new initiatives against phone phreaks by phone-company security



It is not long before I get a chance to see, to hear, Randy at work. Randy is

known among the phone phreaks as perhaps the finest con man in the game. Randy

is blind. He is pale, soft and pear-shaped, he wears baggy pants and a wrinkly

nylon white sport shirt, pushes his head forward from hunched shoulders

somewhat like a turtle inching out of its shell. His eyes wander, crossing and

recrossing, and his forehead is somewhat pimply. He is only sixteen years



But when Randy starts speaking into a telephone mouthpiece his voice becomes so

stunningly authoritative it is necessary to look again to convince yourself it

comes from a chubby adolescent Randy. Imagine the voice of a crack oil-rig

foreman, a tough, sharp, weather-beaten Marlboro man of forty. Imagine the

voice of a brilliant performance-fund gunslinger explaining how he beats the

Dow Jones by thirty percent. Then imagine a voice that could make those two

sound like Stepin Fetchit. That is sixteen-year-old Randy's voice.


He is speaking to a switchman in Detroit. The phone company in Detroit had

closed up two toll-free loop pairs for no apparent reason, although heavy use

by phone phreaks all over the country may have been detected. Randy is telling

the switchman how to open up the loop and make it free again:


"How are you, buddy. Yeah. I'm on the board in here in Tulsa, Oklahoma, and

we've been trying to run some tests on your loop-arounds and we find'em busied

out on both sides.... Yeah, we've been getting a 'BY' on them, what d'ya say,

can you drop cards on 'em? Do you have 08 on your number group? Oh that's

okay, we've had this trouble before, we may have to go after the circuit. Here

lemme give 'em to you: your frame is 05, vertical group 03, horizontal 5,

vertical file 3. Yeah, we'll hang on here.... Okay, found it? Good. Right,

yeah, we'd like to clear that busy out. Right. All you have to do is look for

your key on the mounting plate, it's in your miscellaneous trunk frame. Okay?

Right. Now pull your key from NOR over the LCT. Yeah. I don't know why that

happened, but we've been having trouble with that one. Okay. Thanks a lot

fella. Be seein' ya."


Randy hangs up, reports that the switchman was a little inexperienced with the

loop-around circuits on the miscellaneous trunk frame, but that the loop has

been returned to its free-call status.


Delighted, phone phreak Ed returns the pair of numbers to the active-status

column in his directory. Ed is a superb and painstaking researcher. With

almost Talmudic thoroughness he will trace tendrils of hints through soft-wired

mazes of intervening phone-company circuitry back through complex linkages of

switching relays to find the location and identity of just one toll-free loop.

He spends hours and hours, every day, doing this sort of thing. He has somehow

compiled a directory of eight hundred "Band-six in-WATS numbers" located in

over forty states. Band-six in-WATS numbers are the big 800 numbers -- the

ones that can be dialed into free from anywhere in the country.


Ed the researcher, a nineteen-year-old engineering student, is also a superb

technician. He put together his own working blue box from scratch at age

seventeen. (He is sighted.) This evening after distributing the latest issue

of his in-WATS directory (which has been typed into Braille for the blind phone

phreaks), he announces he has made a major new breakthrough:


"I finally tested it and it works, perfectly. I've got this switching matrix

which converts any touch-tone phone into an M-F-er."


The tones you hear in touch-tone phones are not the M-F tones that operate the

long-distance switching system. Phone phreaks believe A.T.&T. had deliberately

equipped touch tones with a different set of frequencies to avoid putting the

six master M-F tones in the hands of every touch-tone owner. Ed's complex

switching matrix puts the six master tones, in effect put a blue box, in the

hands of every touch-tone owner.


Ed shows me pages of schematics, specifications and parts lists. "It's not easy

to build, but everything here is in the Heathkit catalog."


Ed asks Ralph what progress he has made in his attempts to reestablish a

long-term open conference line for phone phreaks. The last big conference --

the historic "2111" conference -- had been arranged through an unused Telex

test-board trunk somewhere in the innards of a 4A switching machine in

Vancouver, Canada. For months phone phreaks could M-F their way into

Vancouver, beep out 604 (the Vancouver area code) and then beep out 2111 (the

internal phone-company code for Telex testing), and find themselves at any

time, day or night, on an open wire talking with an array of phone phreaks from

coast to coast, operators from Bermuda, Tokyo and London who are phone-phreak

sympathizers, and miscellaneous guests and technical experts. The conference

was a massive exchange of information. Phone phreaks picked each other's

brains clean, then developed new ways to pick the phone company's brains clean.

Ralph gave M F Boogies concerts with his home-entertainment-type electric

organ, Captain Crunch demonstrated his round-the-world prowess with his

notorious computerized unit and dropped leering hints of the "action" he was

getting with his girl friends. (The Captain lives out or pretends to live out

several kinds of fantasies to the gossipy delight of the blind phone phreaks

who urge him on to further triumphs on behalf of all of them.) The somewhat

rowdy Northwest phone-phreak crowd let their bitter internal feud spill over

into the peaceable conference line, escalating shortly into guerrilla warfare;

Carl the East Coast international tone relations expert demonstrated newly

opened direct M-F routes to central offices on the island of Bahrein in the

Persian Gulf, introduced a new phone-phreak friend of his in Pretoria, and

explained the technical operation of the new Oakland-to Vietnam linkages.

(Many phone phreaks pick up spending money by M-F-ing calls from relatives to

Vietnam G.I.'s, charging $5 for a whole hour of trans-Pacific conversation.)


Day and night the conference line was never dead. Blind phone phreaks all over

the country, lonely and isolated in homes filled with active sighted brothers

and sisters, or trapped with slow and unimaginative blind kids in straitjacket

schools for the blind, knew that no matter how late it got they could dial up

the conference and find instant electronic communion with two or three other

blind kids awake over on the other side of America. Talking together on a

phone hookup, the blind phone phreaks say, is not much different from being

there together. Physically, there was nothing more than a two-inch-square wafer

of titanium inside a vast machine on Vancouver Island. For the blind kids

>there< meant an exhilarating feeling of being in touch, through a kind of

skill and magic which was peculiarly their own.


Last April 1, however, the long Vancouver Conference was shut off. The phone

phreaks knew it was coming. Vancouver was in the process of converting from a

step-by-step system to a 4A machine and the 2111 Telex circuit was to be wiped

out in the process. The phone phreaks learned the actual day on which the

conference would be erased about a week ahead of time over the phone company's

internal-news-and-shop-talk recording.


For the next frantic seven days every phone phreak in America was on and off

the 2111 conference twenty-four hours a day. Phone phreaks who were just

learning the game or didn't have M-F capability were boosted up to the

conference by more experienced phreaks so they could get a glimpse of what it

was like before it disappeared. Top phone phreaks searched distant area codes

for new conference possibilities without success. Finally in the early morning

of April 1, the end came.


"I could feel it coming a couple hours before midnight," Ralph remembers. "You

could feel something going on in the lines. Some static began showing up, then

some whistling wheezing sound. Then there were breaks. Some people got cut

off and called right back in, but after a while some people were finding they

were cut off and couldn't get back in at all. It was terrible. I lost it

about one a.m., but managed to slip in again and stay on until the thing

died... I think it was about four in the morning. There were four of us still

hanging on when the conference disappeared into nowhere for good. We all tried

to M-F up to it again of course, but we got silent termination. There was

nothing there."


The Legendary Mark Bernay Turns Out To Be "The Midnight Skulker"


Mark Bernay. I had come across that name before. It was on Gilbertson's

select list of phone phreaks. The California phone phreaks had spoken of a

mysterious Mark Bernay as perhaps the first and oldest phone phreak on the West

Coast. And in fact almost every phone phreak in the West can trace his origins

either directly to Mark Bernay or to a disciple of Mark Bernay.


It seems that five years ago this Mark Bernay (a pseudonym he chose for

himself) began traveling up and down the West Coast pasting tiny stickers in

phone books all along his way. The stickers read something like "Want to hear

an interesting tape recording? Call these numbers." The numbers that followed

were toll-free loop-around pairs. When one of the curious called one of the

numbers he would hear a tape recording pre-hooked into the loop by Bernay which

explained the use of loop-around pairs, gave the numbers of several more, and

ended by telling the caller, "At six o'clock tonight this recording will stop

and you and your friends can try it out. Have fun."


"I was disappointed by the response at first," Bernay told me, when I finally

reached him at one of his many numbers and he had dispensed with the usual "I

never do anything illegal" formalities which experienced phone phreaks open

most conversations.


"I went all over the coast with these stickers not only on pay phones, but I'd

throw them in front of high schools in the middle of the night, I'd leave them

unobtrusively in candy stores, scatter them on main streets of small towns. At

first hardly anyone bothered to try it out. I would listen in for hours and

hours after six o'clock and no one came on. I couldn't figure out why people

wouldn't be interested. Finally these two girls in Oregon tried it out and

told all their friends and suddenly it began to spread."


Before his Johny Appleseed trip Bernay had already gathered a sizable group of

early pre-blue-box phone phreaks together on loop-arounds in Los Angeles.

Bernay does not claim credit for the original discovery of the loop-around

numbers. He attributes the discovery to an eighteen-year-old reform school kid

in Long Beach whose name he forgets and who, he says, "just disappeared one

day." When Bernay himself discovered loop-arounds independently, from clues in

his readings in old issues of the Automatic Electric Technical Journal, he

found dozens of the reform-school kid's friends already using them. However, it

was one of Bernay's disciples in Seattle that introduced phone phreaking to

blind kids. The Seattle kid who learned about loops through Bernay's recording

told a blind friend, the blind kid taught the secret to his friends at a winter

camp for blind kids in Los Angeles. When the camp session was over these kids

took the secret back to towns all over the West. This is how the original

blind kids became phone phreaks. For them, for most phone phreaks in general,

it was the discovery of the possibilities of loop-arounds which led them on to

far more serious and sophisticated phone-phreak methods, and which gave them a

medium for sharing their discoveries.


A year later a blind kid who moved back east brought the technique to a blind

kids' summer camp in Vermont, which spread it along the East Coast. All from a

Mark Bernay sticker.


Bernay, who is nearly thirty years old now, got his start when he was fifteen

and his family moved into an L.A. suburb serviced by General Telephone and

Electronics equipment. He became fascinated with the differences between Bell

and G.T.&E. equipment. He learned he could make interesting things happen by

carefully timed clicks with the disengage button. He learned to interpret

subtle differences in the array of clicks, whirrs and kachinks he could hear on

his lines. He learned he could shift himself around the switching relays of

the L.A. area code in a not-too-predictable fashion by interspersing his own

hook-switch clicks with the clicks within the line. (Independent phone

companies -- there are nineteen hundred of them still left, most of them tiny

island principalities in Ma Bell's vast empire -- have always been favorites

with phone phreaks, first as learning tools, then as Archimedes platforms from

which to manipulate the huge Bell system. A phone phreak in Bell territory

will often M-F himself into an independent's switching system, with switching

idiosyncrasies which can give him marvelous leverage over the Bell System.


"I have a real affection for Automatic Electric Equipment," Bernay told me.

"There are a lot of things you can play with. Things break down in interesting



Shortly after Bernay graduated from college (with a double major in chemistry

and philosophy), he graduated from phreaking around with G.T.&E. to the Bell

System itself, and made his legendary sticker-pasting journey north along the

coast, settling finally in Northwest Pacific Bell territory. He discovered

that if Bell does not break down as interestingly as G.T.&E., it nevertheless

offers a lot of "things to play with."


Bernay learned to play with blue boxes. He established his own personal

switchboard and phone-phreak research laboratory complex. He continued his

phone-phreak evangelism with ongoing sticker campaigns. He set up two recording

numbers, one with instructions for beginning phone phreaks, the other with

latest news and technical developments (along with some advanced instruction)

gathered from sources all over the country.


These days, Bernay told me, he had gone beyond phone-phreaking itself. "Lately

I've been enjoying playing with computers more than playing with phones. My

personal thing in computers is just like with phones, I guess -- the kick is in

finding out how to beat the system, how to get at things I'm not supposed to

know about, how to do things with the system that I'm not supposed to be able

to do."


As a matter of fact, Bernay told me, he had just been fired from his

computer-programming job for doing things he was not supposed to be able to do.

he had been working with a huge time-sharing computer owned by a large

corporation but shared by many others. Access to the computer was limited to

those programmers and corporations that had been assigned certain passwords.

And each password restricted its user to access to only the one section of the

computer cordoned off from its own information storager. The password system

prevented companies and individuals from stealing each other's information.


"I figured out how to write a program that would let me read everyone else's

password," Bernay reports. "I began playing around with passwords. I began

letting the people who used the computer know, in subtle ways, that I knew

their passwords. I began dropping notes to the computer supervisors with hints

that I knew what I know. I signed them 'The Midnight Skulker.' I kept getting

cleverer and cleverer with my messages and devising ways of showing them what I

could do. I'm sure they couldn't imagine I could do the things I was showing

them. But they never responded to me. Every once in a while they'd change the

passwords, but I found out how to discover what the new ones were, and I let

them know. But they never responded directly to the Midnight Skulker. I even

finally designed a program which they could use to prevent my program from

finding out what it did. In effect I told them how to wipe me out, The

Midnight Skulker. It was a very clever program. I started leaving clues about

myself. I wanted them to try and use it and then try to come up with something

to get around that and reappear again. But they wouldn't play. I wanted to

get caught. I mean I didn't want to get caught personally, but I wanted them

to notice me and admit that they noticed me. I wanted them to attempt to

respond, maybe in some interesting way."

Finally the computer managers became concerned enough about the threat of

information-stealing to respond. However, instead of using The Midnight

Skulker's own elegant self-destruct program, they called in their security

personnel, interrogated everyone, found an informer to identify Bernay as The

Midnight Skulker, and fired him.


"At first the security people advised the company to hire me full-time to

search out other flaws and discover other computer freaks. I might have liked

that. But I probably would have turned into a double double agent rather than

the double agent they wanted. I might have resurrected The Midnight Skulker

and tried to catch myself. Who knows? Anyway, the higher-ups turned the whole

idea down."


You Can Tap the F.B.I.'s Crime Control Computer in the Comfort of Your Own

Home, Perhaps


Computer freaking may be the wave of the future. It suits the phone-phreak

sensibility perfectly. Gilbertson, the blue-box inventor and a lifelong phone

phreak, has also gone on from phone-phreaking to computer-freaking. Before he

got into the blue-box business Gilbertson, who is a highly skilled programmer,

devised programs for international currency arbitrage.


But he began playing with computers in earnest when he learned he could use his

blue box in tandem with the computer terminal installed in his apartment by the

instrumentation firm he worked for. The print-out terminal and keyboard was

equipped with acoustical coupling, so that by coupling his little ivory

Princess phone to the terminal and then coupling his blue box on that, he could

M-F his way into other computers with complete anonymity, and without charge;

program and re-program them at will; feed them false or misleading information;

tap and steal from them. He explained to me that he taps computers by busying

out all the lines, then going into a verification trunk, listening into the

passwords and instructions one of the time sharers uses, and them M-F-ing in

and imitating them. He believes it would not be impossible to creep into the

F.B.I's crime control computer through a local police computer terminal and

phreak around with the F.B.I.'s memory banks. He claims he has succeeded in

re-programming a certain huge institutional computer in such a way that it has

cordoned off an entire section of its circuitry for his personal use, and at

the same time conceals that arrangement from anyone else's notice. I have been

unable to verify this claim.


Like Captain Crunch, like Alexander Graham Bell (pseudonym of a

disgruntled-looking East Coast engineer who claims to have invented the black

box and now sells black and blue boxes to gamblers and radical heavies), like

most phone phreaks, Gilbertson began his career trying to rip off pay phones as

a teenager. Figure them out, then rip them off. Getting his dime back from

the pay phone is the phone phreak's first thrilling rite of passage. After

learning the usual eighteen different ways of getting his dime back, Gilbertson

learned how to make master keys to coin-phone cash boxes, and get everyone

else's dimes back. He stole some phone-company equipment and put together his

own home switchboard with it. He learned to make a simple "bread-box" device,

of the kind used by bookies in the Thirties (bookie gives a number to his

betting clients; the phone with that number is installed in some widow lady's

apartment, but is rigged to ring in the bookie's shop across town, cops trace

big betting number and find nothing but the widow).


Not long after that afternoon in 1968 when, deep in the stacks of an

engineering library, he came across a technical journal with the phone tone

frequencies and rushed off to make his first blue box, not long after that

Gilbertson abandoned a very promising career in physical chemistry and began

selling blue boxes for $1,500 apiece.


"I had to leave physical chemistry. I just ran out of interesting things to

learn," he told me one evening. We had been talking in the apartment of the

man who served as the link between Gilbertson and the syndicate in arranging

the big $300,000 blue-box deal which fell through because of legal trouble.

There has been some smoking.


"No more interesting things to learn," he continues. "Physical chemistry turns

out to be a sick subject when you take it to its highest level. I don't know.

I don't think I could explain to you how it's sick. You have to be there. But

you get, I don't know, a false feeling of omnipotence. I suppose it's like

phone-phreaking that way. This huge thing is there. This whole system. And

there are holes in it and you slip into them like Alice and you're pretending

you're doing something you're actually not, or at least it's no longer you

that's doing what you thought you were doing. It's all Lewis Carroll.

Physical chemistry and phone-phreaking. That's why you have these phone-phreak

pseudonyms like The Cheshire Cat, the Red King, and The Snark. But there's

something about phone-phreaking that you don't find in physical chemistry." He

looks up at me:


"Did you ever steal anything?"


"Well yes, I..."


"Then you know! You know the rush you get. It's not just knowledge, like

physical chemistry. It's forbidden knowledge. You know. You can learn about

anything under the sun and be bored to death with it. But the idea that it's

illegal. Look: you can be small and mobile and smart and you're ripping off

somebody large and powerful and very dangerous."


People like Gilbertson and Alexander Graham Bell are always talking about

ripping off the phone company and screwing Ma Bell. But if they were shown a

single button and told that by pushing it they could turn the entire circuitry

of A.T.&T. into molten puddles, they probably wouldn't push it. The

disgruntled-inventor phone phreak needs the phone system the way the lapsed

Catholic needs the Church, the way Satan needs a God, the way The Midnight

Skulker needed, more than anything else, response.


Later that evening Gilbertson finished telling me how delighted he was at the

flood of blue boxes spreading throughout the country, how delighted he was to

know that "this time they're really screwed." He suddenly shifted gears.


"Of course. I do have this love/hate thing about Ma Bell. In a way I almost

like the phone company. I guess I'd be very sad if they were to disintegrate.

In a way it's just that after having been so good they turn out to have these

things wrong with them. It's those flaws that allow me to get in and mess with

them, but I don't know. There's something about it that gets to you and makes

you want to get to it, you know."


I ask him what happens when he runs out of interesting, forbidden things to

learn about the phone system.


"I don't know, maybe I'd go to work for them for a while."


"In security even?"


"I'd do it, sure. I just as soon play -- I'd just as soon work on either



"Even figuring out how to trap phone phreaks? I said, recalling Mark Bernay's



"Yes, that might be interesting. Yes, I could figure out how to outwit the

phone phreaks. Of course if I got too good at it, it might become boring

again. Then I'd have to hope the phone phreaks got much better and outsmarted

me for a while. That would move the quality of the game up one level. I might

even have to help them out, you know, 'Well, kids, I wouldn't want this to get

around but did you ever think of -- ?' I could keep it going at higher and

higher levels forever."


The dealer speaks up for the first time. He has been staring at the soft

blinking patterns of light and colors on the translucent tiled wall facing him.

(Actually there are no patterns: the color and illumination of every tile is

determined by a computerized random-number generator designed by Gilbertson

which insures that there can be no meaning to any sequence of events in the



"Those are nice games you're talking about," says the dealer to his friend.

"But I wouldn't mind seeing them screwed. A telephone isn't private anymore.

You can't say anything you really want to say on a telephone or you have to go

through that paranoid bullshit. 'Is it cool to talk on the phone?' I mean,

even if it is cool, if you have to ask 'Is it cool,' then it isn't cool. You

know. 'Is it cool,' then it isn't cool. You know. Like those blind kids,

people are going to start putting together their own private telephone

companies if they want to really talk. And you know what else. You don't hear

silences on the phone anymore. They've got this time-sharing thing on

long-distance lines where you make a pause and they snip out that piece of time

and use it to carry part of somebody else's conversation. Instead of a pause,

where somebody's maybe breathing or sighing, you get this blank hole and you

only start hearing again when someone says a word and even the beginning of the

word is clipped off. Silences don't count -- you're paying for them, but they

take them away from you. It's not cool to talk and you can't hear someone when

they don't talk. What the hell good is the phone? I wouldn't mind seeing them

totally screwed."


The Big Memphis Bust


Joe Engressia never wanted to screw Ma Bell. His dream had always been to work

for her.


The day I visited Joe in his small apartment on Union Avenue in Memphis, he was

upset about another setback in his application for a telephone job.


"They're stalling on it. I got a letter today telling me they'd have to

postpone the interview I requested again. My landlord read it for me. They

gave me some runaround about wanting papers on my rehabilitation status but I

think there's something else going on."


When I switched on the 40-watt bulb in Joe's room -- he sometimes forgets when

he has guests -- it looked as if there was enough telephone hardware to start a

small phone company of his own.


There is one phone on top of his desk, one phone sitting in an open drawer

beneath the desk top. Next to the desk-top phone is a cigar-box-size M-F

device with big toggle switches, and next to that is some kind of switching and

coupling device with jacks and alligator plugs hanging loose. Next to that is

a Braille typewriter. On the floor next to the desk, lying upside down like a

dead tortoise, is the half-gutted body of an old black standard phone. Across

the room on a torn and dusty couch are two more phones, one of them a

touch-tone model; two tape recorders; a heap of phone patches and cassettes,

and a life-size toy telephone.


Our conversation is interrupted every ten minutes by phone phreaks from all

over the country ringing Joe on just about every piece of equipment but the toy

phone and the Braille typewriter. One fourteen-year-old blind kid from

Connecticut calls up and tells Joe he's got a girl friend. He wants to talk to

Joe about girl friends. Joe says they'll talk later in the evening when they

can be alone on the line. Joe draws a deep breath, whistles him off the air

with an earsplitting 2600-cycle whistle. Joe is pleased to get the calls but he

looked worried and preoccupied that evening, his brow constantly furrowed over

his dark wandering eyes. In addition to the phone-company stall, he has just

learned that his apartment house is due to be demolished in sixty days for

urban renewal. For all its shabbiness, the Union Avenue apartment house has

been Joe's first home-of-his-own and he's worried that he may not find another

before this one is demolished.


But what really bothers Joe is that switchmen haven't been listening to him.

"I've been doing some checking on 800 numbers lately, and I've discovered that

certain 800 numbers in New Hampshire couldn't be reached from Missouri and

Kansas. Now it may sound like a small thing, but I don't like to see sloppy

work; it makes me feel bad about the lines. So I've been calling up switching

offices and reporting it, but they haven't corrected it. I called them up for

the third time today and instead of checking they just got mad. Well, that

gets me mad. I mean, I do try to help them. There's something about them I

can't understand -- you want to help them and they just try to say you're

defrauding them."


It is Sunday evening and Joe invites me to join him for dinner at a Holiday

Inn. Frequently on Sunday evening Joe takes some of his welfare money, calls a

cab, and treats himself to a steak dinner at one of Memphis' thirteen Holiday

Inns. (Memphis is the headquarters of Holiday Inn. Holiday Inns have been a

favorite for Joe ever since he made his first solo phone trip to a Bell

switching office in Jacksonville, Florida, and stayed in the Holiday Inn there.

He likes to stay at Holiday Inns, he explains, because they represent freedom

to him and because the rooms are arranged the same all over the country so he

knows that any Holiday Inn room is familiar territory to him. Just like any



Over steaks in the Pinnacle Restaurant of the Holiday Inn Medical Center on

Madison Avenue in Memphis, Joe tells me the highlights of his life as a phone



At age seven, Joe learned his first phone trick. A mean baby-sitter, tired of

listening to little Joe play with the phone as he always did, constantly, put a

lock on the phone dial. "I got so mad. When there's a phone sitting there and

I can't use it... so I started getting mad and banging the receiver up and

down. I noticed I banged it once and it dialed one. Well, then I tried

banging it twice...." In a few minutes Joe learned how to dial by pressing the

hook switch at the right time. "I was so excited I remember going 'whoo whoo'

and beat a box down on the floor."


At age eight Joe learned about whistling. "I was listening to some intercept

non working-number recording in L.A.- I was calling L.A. as far back as that,

but I'd mainly dial non working numbers because there was no charge, and I'd

listen to these recordings all day. Well, I was whistling 'cause listening to

these recordings can be boring after a while even if they are from L.A., and

all of a sudden, in the middle of whistling, the recording clicked off. I

fiddled around whistling some more, and the same thing happened. So I called

up the switch room and said, 'I'm Joe. I'm eight years old and I want to know

why when I whistle this tune the line clicks off.' He tried to explain it to

me, but it was a little too technical at the time. I went on learning. That

was a thing nobody was going to stop me from doing. The phones were my life,

and I was going to pay any price to keep on learning. I knew I could go to

jail. But I had to do what I had to do to keep on learning."


The phone is ringing when we walk back into Joe's apartment on Union Avenue.

It is Captain Crunch. The Captain has been following me around by phone,

calling up everywhere I go with additional bits of advice and explanation for

me and whatever phone phreak I happen to be visiting. This time the Captain

reports he is calling from what he describes as "my hideaway high up in the

Sierra Nevada." He pulses out lusty salvos of M-F and tells Joe he is about to

"go out and get a little action tonight. Do some phreaking of another kind, if

you know what I mean." Joe chuckles.


The Captain then tells me to make sure I understand that what he told me about

tying up the nation's phone lines was true, but that he and the phone phreaks

he knew never used the technique for sabotage. They only learned the technique

to help the phone company.


"We do a lot of troubleshooting for them. Like this New Hampshire/Missouri

WATS-line flaw I've been screaming about. We help them more than they know."


After we say good-bye to the Captain and Joe whistles him off the line, Joe

tells me about a disturbing dream he had the night before: "I had been caught

and they were taking me to a prison. It was a long trip. They were taking me

to a prison a long long way away. And we stopped at a Holiday Inn and it was

my last night ever using the phone and I was crying and crying, and the lady at

the Holiday Inn said, 'Gosh, honey, you should never be sad at a Holiday Inn.

You should always be happy here. Especially since it's your last night.' And

that just made it worse and I was sobbing so much I couldn't stand it."


Two weeks after I left Joe Engressia's apartment, phone-company security agents

and Memphis police broke into it. Armed with a warrant, which they left pinned

to a wall, they confiscated every piece of equipment in the room, including his

toy telephone. Joe was placed under arrest and taken to the city jail where he

was forced to spend the night since he had no money and knew no one in Memphis

to call.


It is not clear who told Joe what that night, but someone told him that the

phone company had an open-and-shut case against him because of revelations of

illegal activity he had made to a phone-company undercover agent.


By morning Joe had become convinced that the reporter from Esquire, with whom

he had spoken two weeks ago, was the undercover agent. He probably had ugly

thoughts about someone he couldn't see gaining his confidence, listening to him

talk about his personal obsessions and dreams, while planning all the while to

lock him up.


"I really thought he was a reporter," Engressia told the Memphis Press-Seminar.

"I told him everything...." Feeling betrayed, Joe proceeded to confess

everything to the press and police.


As it turns out, the phone company did use an undercover agent to trap Joe,

although it was not the Esquire reporter.


Ironically, security agents were alerted and began to compile a case against

Joe because of one of his acts of love for the system: Joe had called an

internal service department to report that he had located a group of defective

long-distance trunks, and to complain again about the New Hampshire/Missouri

WATS problem. Joe always liked Ma Bell's lines to be clean and responsive. A

suspicious switchman reported Joe to the security agents who discovered that

Joe had never had a long-distance call charged to his name.


Then the security agents learned that Joe was planning one of his phone trips

to a local switching office. The security people planted one of their agents

in the switching office. He posed as a student switchman and followed Joe

around on a tour. He was extremely friendly and helpful to Joe, leading him

around the office by the arm. When the tour was over he offered Joe a ride back

to his apartment house. On the way he asked Joe -- one tech man to another --

about "those blue boxers" he'd heard about. Joe talked about them freely,

talked about his blue box freely, and about all the other things he could do

with the phones.


The next day the phone-company security agents slapped a monitoring tape on

Joe's line, which eventually picked up an illegal call. Then they applied for

the search warrant and broke in.


In court Joe pleaded not guilty to possession of a blue box and theft of

service. A sympathetic judge reduced the charges to malicious mischief and

found him guilty on that count, sentenced him to two thirty-day sentences to be

served concurrently and then suspended the sentence on condition that Joe

promise never to play with phones again. Joe promised, but the phone company

refused to restore his service. For two weeks after the trial Joe could not be

reached except through the pay phone at his apartment house, and the landlord

screened all calls for him.


Phone-phreak Carl managed to get through to Joe after the trial, and reported

that Joe sounded crushed by the whole affair.


"What I'm worried about," Carl told me, "is that Joe means it this time. The

promise. That he'll never phone-phreak again. That's what he told me, that

he's given up phone-phreaking for good. I mean his entire life. He says he

knows they're going to be watching him so closely for the rest of his life

he'll never be able to make a move without going straight to jail. He sounded

very broken up by the whole experience of being in jail. It was awful to hear

him talk that way. I don't know. I hope maybe he had to sound that way. Over

the phone, you know."


He reports that the entire phone-phreak underground is up in arms over the

phone company's treatment of Joe. "All the while Joe had his hopes pinned on

his application for a phone-company job, they were stringing him along getting

ready to bust him. That gets me mad. Joe spent most of his time helping them

out. The bastards. They think they can use him as an example. All of sudden

they're harassing us on the coast. Agents are jumping up on our lines. They

just busted ------'s mute yesterday and ripped out his lines. But no matter

what Joe does, I don't think we're going to take this lying down."


Two weeks later my phone rings and about eight phone phreaks in succession say

hello from about eight different places in the country, among them Carl, Ed,

and Captain Crunch. A nationwide phone-phreak conference line has been

reestablished through a switching machine in --------, with the cooperation of

a disgruntled switchman.


"We have a special guest with us today," Carl tells me.


The next voice I hear is Joe's. He reports happily that he has just moved to a

place called Millington, Tennessee, fifteen miles outside of Memphis, where he

has been hired as a telephone-set repairman by a small independent phone

company. Someday he hopes to be an equipment troubleshooter.


"It's the kind of job I dreamed about. They found out about me from the

publicity surrounding the trial. Maybe Ma Bell did me a favor busting me.

I'll have telephones in my hands all day long."


"You know the expression, 'Don't get mad, get even'?" phone-phreak Carl asked

me. "Well, I think they're going to be very sorry about what they did to Joe

and what they're trying to do to us."
