TAP No. 15 - 1973 Credit Card Code, T Network

Co-founder Al Bell writes an extended origin-story editorial framing YIPL as a deliberate provocation against the phone company as a stand-in for the military-industrial complex, previewing a coming legal showdown. Explains the Black Box for dodging message-unit charges, a whistled 2600Hz trick to flood Ma Bell’s new blue-box detectors with false alarms, and launches a reader-info-trading department called ‘Destructory Assistance.’ Also covers commercial blue-box detector products on the market and a ‘T network’ circuit project.
Well, it's a new year, and I feel many of you want to know
the full story behind YIPL. My name is Al Bell, and a few
of us started this on Mayday, in 1971. YIPL is the result of
one phone phreak‘s realization that the Military-Industrial
Komplex is not just a term you learn in school, but a force
that controls the planet Earth from the country America. It
became apparert to me that the vast majority of people are
being used as pawns, as slaves to make a few multi-million-
aires even richer. It's all done through MIC, whose main
tactic is Divide and Conquer. Most people don't agree with
me, thus proving how effective that tactic is, So people war
with each other, and the pigs get richer. And one company
bas accumulated such an impressive shelf of pork that this
company, more than any other company, represents the
robber -barrons that dare to defecate on our world. This
company is, in fact, the largest company in the World. Ma
Bell is a mother of a fucker.
‘Though we are quite effective in helping people to steal
back what is rightfully theirs, and we have also truly given
@ veritable kick in the groin, our purpose is mainly to make
people think the question, "Why are they ripping
off the phone
company?", because once they do the answer will be obvious.
YIPL members are actors in a play, and the world is watch-
ing. And we're having a lot of fun!
1973 looks like the year of the climax. The phone company's
on our ass but if they touch us it won't be quietly. A lot of
people hate the phone company from down deep, but they've
never really given it enough thought to link it with world
problems. If YIPL goes on trial, people are going to ask
themselves questions, and that's all we want,
YIPL has in the past been too difficult to understand, and
we're trying to understand. Often we've been technically sim-
Pleminded, and we apologise to the numerous geniuses out
there who patiently write in and tell us, but we're learning.
Basically we're trying to digest the hard stuff, and print in
Simpler terms for use by beginners up. But there are lots
of things all of us can do. For example, Ma Bells new ways
of catching blue boxers will be fouled up if we put in false
indications of a BB. One way is to pick up your phone, and
all your friends, dial long-distance info, and whistling 2600

A SURE CURE FOR MESSAGE UNITS
‘The major cause of high phone bills are those little
message units, The only areas with unlimited outgoing
service are the golden ghettos; those who could afford
it but don't have to pay. Anyway, you can get around
many of those annoying message units with the Black Box,
also known as a mute, an Agnew, an incoming device. The
versatile YIPL model is the simplest unit you can build, if
you haven't done so, get issue no. ll and do it,
‘The Black Box won't Jet you receive calls free unless they
are long distance, If they're local, and you answer on "Free"
you'll be disconnected in up to 20 seconds. However, many
times we call friends just for a second to see if they're home,
or to tell them to come down an open the door, or pick them
up because their train just arrived. These calls often last
less than 15 seconds, but they cost message units, and those
Uttle buggers add up. (No offense meant). Here's how todo
it
‘When you're expecting your friend to call, flip switch to
"Free" and then pick up. The phone
will be ringing loudly in
your ear, but you'll be able to hear your friend between the

Dear Phellow Phreax,
‘Two queries for you. First: Lets say I wanted to call a transit
country. Dow I need KP2. How do I go about using it?
Seconé How do I verify a line once the operator plugs me into

ge two lines in your house, they must be the same type
of service. They won't let you get an unlimited and a regular
fone. Either one or the other, Must make more bux, you know,
One more thing; If you want to get equiptment, any kind that's
used in a home, (touch-tone, trim-line, speaker-phone, card
dialer, etc.) get a friend, or yourself, who is moving in a few
weeks to have a bunch of goodies installed. If it gets stolen after
you move, its not your fault. Ma Bell eats tricky dick, X.
One reader reports that he built a black box and 10,000 ohms
was too low to disconnect in his area. If anyone has doubt of
their area, test your black box as in the instructions(issue 11).
Simply pick up your phor.2, and when you get a dial tone, switch
to "Free", If the dial tone stops, cool, otherwise use a higher
resistor, like 12,000 ohms, or 15,000 ohms. Try not to go lower
than 10, 000 ohms.

rings, and hany up, You can answer them if you want, Even
if the phone is tapped, the beauty of this system is that those
listening can't tell if the two of you are simply on extensions
at the calling party's house! And since your friend hangs up
before you answer, of course there is no charge,
Sure, this isn't for long conversations, but it's easy, fun
and saves money on those little messaye units. Even though
a special, expensive test unit can detect a black box on your
line if they know you already have one, it won't detect it at
all if you use it like this for under two minutes, or fifteen
ings, Don't hesitate to try it if you have a message unit
problem each month, Our black box plans are so easy that
anyone, and you too, can build it for one dollar in 30 minutes.

INFORMATION
Personnel answer and ask caller to identify self, and then
they connect you to computor who reads back your number.
Sometimes only during daytime. Ident(Reno)-444, Lake Tahoe-
21, SF Bay Area touchtone check is 960-then last 4 digits of
your line. When you hear dial tone dial 1 through 0. If tones
and levels correct, "beep-beep" will follow. Dial 2 and hang
up, and will ring tack,
If it
is true that Bell is making a record of incoming calls
to called numbers ringing for more than 5 minutes, this can
be an invitation to really bug them by calling (locally) assor-
ted places-stores at night, outdoor pay phones, etc, Let them
ring endlessly and they'li make needless printouts or te up
equiptment doing so. Unable to confirm that they're doing this
but at least they're experimenting with it.
Recent trick locally if they have you under suspicion is to
have a foreman accompany installer or repairn:an to your
Place. Joker is really a security agent and have been known
to leave radio bugs on premises, not on phone line. I know of
one concealed behind head board in bedroom to get "pillow-
talk". Never allow more than one installer on place, or if you
have reason not to allow them to enter-someone sick, scarlet
fever, etc.

Cheap way to get 2 lines in your home at lowest cost in Cal,
Get a one party flatrate, Have it put on "vacation rate" which
good to max. 7 months that can then be extended indefinitely,
Possibility little argument with business office rep that you're
on vacation. Use line for outgoing call, at half price. Then order
@ one party "survival fone"which allows 30 mu. Have the one
party flatrate unlisted. The 30 mu. listed and for incoming calls
will cost $2.25/mo, The flatrate is $4.80; vacation rate $2. 40,
Thus you get two lines(one 2-way and one outgoing only) for $4. 65.
That's less than the flatrate two-way. Of course the 30 mu. can
be used for outgoing, no extra charge up to 30. Only catch is the
"survival" fone not supposed to be in same "living quarters" as
other fones, but have it installed in extra bedroom that belongs
to a boarder or to your "Aunt Minnie", Have them installed at

iman device prints out any number you dial with a Blue Box
after it detects 2600 cycles on the line. Though the device
has only one line capacity, it can be put on the outgoing
lines of a Central Office, and any one of the 10, 000 lines
will turn the device on and record the number boxed. Of
course a phoney credit card call will also give them the
number dialed, and we get away with those all the time.
But make sure that if you call friends with a box, they
should not use a box on their line, and don't stay on long
enough to be traced.

we will send you back other information, If you want a specific
type of info, let us know and we'll try, but we have almost nothing
right now. Otherwise, we'll send you random information such
as would be printed in YIPL; the same amount that you send us.
However, you must send us a stamped, self-addressed envelope

BUILD A°T’ NETWORK FOR FUN & PROFIT
If you live or work near a pay phone, then you might have
an excellent opportunity waiting for you. It's called the
T network, and it gives you back your money after a
phone call. There are many variations, but right now we'll
explain how it works and the simplest way to do it.
‘The pay phone stores your money, either to return it or
to deposit it, depending upon whether a + or a - pulse of
180 volts is sent to the phone. The pulse is sent down both
the red and green wires and returns to ground through the
yellow or the black wires, sometimes both. These wires
are in a thin cable usually running along the wall near the
Phone. In an inconspicuous way, carefully slice along the
wire , exposing the 4 wires. Move the red and green wires
out of the way, and cut the black and yellow wires, then strip
off 3/4" of insulation from all four cut ends, Tie the
Y& B
on the phone side together, and do the dame for the other pair.
‘Touch the two twisted pairs together now, and dial direct a
long distance call, When the operator comes on, deposit the
amount she asks for, While talking to your friend, discon~
nect the two pairs, because after approximately 2 minutes
and 40 seconds, the pulse will come to collect your initial
deposit, However, the pulse will no longer be able to flow
‘through the phone because you disconnected the ground wires.
It's best to hang up when the operator comes on after 3 minu--
tes and says "End of initial period, signal when through". Now
wait to make sure another pulse doesn't collect your money,
for at least ten seconds. Then pick up the phone again, and
re-conncct the wires. You will get a dial tone, so hang up
and JACK POT, all your money will come down again.
Since the phone company usually kncws how much there
should be in the phone at collection time, they will notice
something amiss. However, you can pull this off for a few
months and up to a few hundred dollars in calls and then be
sure never to do it again, because if they find your broken
wires, they'll stakeout the phone to catch you. Best to de it
for only 4 weeks and then stop for 6 months,
Keep wires securely twisted together
when not in use, so phone works 0. k.
