TAP No. 7 - Tuning Your Organ, 3-Slot Ripoffs

Explains the redesigned 1972 credit card code (moving the check letter from the sixth to the fourth digit) and a separate ‘Code Billing System’ exploit with a sample billing number. Encourages readers to prank-call Southern Bell’s chief of security, Gerald E. McDaniels, at his office and home numbers. Includes an early write-up of what would become the ‘black box’ (letting a home phone receive long-distance calls for free) and a call to boycott ITT over its war contracting and PR spending.

Our demented readers have been deluging
us with requests for suppliers of #14
brass washers.
We want to know where
these items can be mail-ordered from,
SO we can publish an expose' of such
a dastardly corporation that would sell
slugs good in pay phones, drink and
food machines, laundromats and parking
meters. So if any of you people run
across such a scummy outfit, be sure
to alert YIPL as to the adress ,and the
price of the washers.
We have recently been advised that a
seemingly outasight deal is a gyp. The
Book Clubs, who advertise in the New
York Times every Sunday(Book Review
Section) don't tell their customers that
the books come with untrimmed pages that
look like shit. For this unspeakable
crime,’we urge YIPL readers to order the
four free books(or 4for a buck) and to
refuse to
pages. Only order from companies that do
not require a signature..Also, continue
ordering for aeeks afterwards for ail
your friends if they refuse to remedy this
despicable situation. And if you can
believe it, The Book of the Month Club
says"'These books are identical to the
publishers editions, ...in quality."
What a fucking lie,
pay if they come with untrimmed
REVISED
Yipl readers! We are being attacked!
The U.S. Government is undermining
our correspondence, and stealing your
money.
This is happening all the way
down the line to the postmen who look
through your mail before they decide
to deliver it to you or not. Don't
mail letters to YIPL with your local
mailman. Drop them in a mailbox.Only
send checks to YIPL,not cash. And
most of all, place your stamps 1 1/2
inches lower on the envelope. And
don't forget the zip code. We can't
allow them to have an excuse for
confiscating our mail.
As long as this communications gap
exists, we have to ask
you to help.
If your YIPL gets through, Xerox it
and distribute it at head shops,at
clothing stores, colleges, riots,
conventions, to friends ,hitchers,
schools.This is vital for reaching
the masses whom the Government fears.
One reader suggested labels that
stick to phones, subway doors,etc.,
that have useful information about
freebies.
Happy New Year to all our friends,
especially the New York Tel. Co.
striking workers.
1972 will provide fun for many

in San Diego this summer.
See you there.

This establishment fuck is beautiful,
it has worked everytime,for everyone.
It will work especially well now
around Christmas time.
Just go into
a large store, pick something off the
shelf (packaged) and quickly walk over
to the cashier and tell her you would
like to return this item.
Since you
have no sales slip(you received this
as a gift and already have one) the
sales girl will give you a merchandise
credit and you're free to look around
and choose anything your crooked litr
tle heart desires.
Also,if its extra
cash you want 4 need, save sales slips
when you do shop and after Christmas
do the same thing as above but now
you have a sales receipt-make sure its
for the same amount please-so the
cashier will give you cash.if you
can't find anything you want to ex-
change it for,
Its really a rush!

Dear YIPL,
My name is
»presently
I am being held prisoner by Monroe
State Reformatory, hopefully not for
very damn longer,it's hard telling
because I am on appeal,who knows how
long they can take on a appeal these
days.
Several months ago I mailed you some
stamped envelopes, so that I could get
onto your mailing list. Well, low and
behold I received an issue today, and
I find it extremely interesting,I re-
ceived November's issue #6. I am going
to try to send you a few more stamped
envelopes with this letter, they are
about the only assets I have right now
and I'm pretty broke to tell the truth.
The State "gives" us three stamped
envelopes a week, and so you get to
saving them up for trading and such,
but it takes-a while. So I hope that
they ‘come to use for you.
I was wondering though,if it would be
possible to send me any ack issues,
I sure would appreciate it.
I can dig
finding out about installing phones,
in and around and under different con-
ditions.
(continued in fourth column)
Dear Sir:
I have a problem which you might be
able to help with. The series of events
went like this:
1. A friend gave me a phone credit card
number and said it was 0O,K. to use.
2.
I used it for about 3 months,making
some person to person calls(the friend
who gave it to me said to keep the
costs down that way).
3.0n Nov. 23, Ohio Bell called my friends
and coaxed them into saying that I was
the person who called them from this
area.
4. The next day the phone company called
me and explained that the card was
invalid.
They then said that I should
pay for the calls. When I declined, they
said they would forward the matter to
their securities dept.
If you could,please advise me on what to
do,since I don't want to pay for all
those calls.D.G.,Painesville,Ohio
-Try this: Contact your friends and
tell them to change their story if the
phone company calls them again. They
should say that "many people use this
phone operator" and they wish they
could help but they can't. When the
phone company contacts you again, deny
the charges. By the way, don't use a
credit card no. for more than a month,
or call friends who will buckle under
a threat that the phone company will
more than likely not carry through.

Dear Friends:
In your pay phone issue you suggest
that a proper way to fuck a pay phone
is to glue the coin slots or the coin
box lock with epoxy glue and to use
a syringe. Excellent injectors for this
type of work can be purchased from the
Brook Stone Company, 12 for $4.95 plus
-90 postage. They look like syringes
with a needle. The order number is
Z-1135.3 and the address is
Brookstone Company
Dept. C
9 Brookstone Building
Petersborough,N.H., 03458
A good pair of bolt cutters can be had
from Brookstone. It's 14" long, easy to
hide under a coat or pants leg. They
cost $8.95 plus $1.15. I have a pair and
they cut armored cable like string.
Can any of you send me some #14
brass washers or an address where I
can send for some? I can't seem to find
fm up here.

I have one little idea, that I remem-
ber from way back, and so it is very
possible that you may already know
it. If you tear about a half inch
wide
strip from the telephone book,
in a pay booth,and tear it so you have
a half by ten inch strip of cardboard,
you then take it and slip it down
the quarter slot in the phone, and
just drop a penny down the slot and
puil the cardboard from the phone,
but do it very slowly, and you might
try even jiggling it a bit when you
do it,once you get the hang of it it
is easier than shit, and you can call
long distance the same way, when the
operator asks you to put the money in,
just drop in your pennys into the
nickel slot, wiggle the cardboard in
the quarter slot, and it rings up the
bread, it might sound like a big
hassle, but it really isn't at all.
Well, guess I will close now, thanks
again, I really like issue#6 and think
that something of this sort should
have come out ages ago,especially when
I was on the streets, I could have
dug getting in to it then. Also, if
you can,will you send me an extra copy
of your back issues? You may have
sent them to me already, and the pigs
here could have intercepted them, but
I think if you mail just one issue at
a time, that they will come through
OK, at least I will let you know what
happens,thanks again. In love and
peace for all, John Doe
Abby Hoffman,
Here are a few sure-fire ways to rip
off Maw Bell.
On the three slot pay
phones there is a plastic case on the
bottom, underneath the phone. Now when
you unscrew the center screw it will
reveal 4 screws with a wire behind
each. Now you take the bottom right
screw and unscrew it enough to take
the wire out. Now you take the wire
and touch it tothe top right wire and
presto-you got a dial tone. Call away
A way you can get money is to unhitch
the bottom right wire and put some
tape around it so it doesn't touch any
other part. Now the phone doesn't work
but the people don't know this so they
put money in and nothing. So you come
back in a week and take the tape off
and put the wire back under its screw,
hang up the phone and you hit the jack
pot-money-money-money. (P.S.if it don't
work just push the coin return but
the above will work so you don't have
nothing to worry about). M.R., Hadley,
Mass.
Tuning Your ORGAN
Probably one of the hardest parts of constructing our toy organ is
finding a tuning method.
One proven method is to use an electric
organ. However, many of these are unstable and nay have drifted.
The Hammond B3 or C3 is a good instrument to use. With the highest
drawbar pulled out only, the following notes, starting with the low
F, closely agree with the frquencies specified
F5 697 Hz,
A6 880 Hz.
A better idea is,of course, to use an accurate
C#6 1108 Hz.
signal generator.
If the generator is off, you

can Calibrate it by using A= 880 Hz. Or, Ma Bell
F¥6 1479 Hz,
herself can help you. A touch tone phone operates
G#6 1661 Hz.
very accurately with each row and column having
°
a single frequency.
To get 697 Hz, simply press
E7 2637 Hz,
any two buttons on the top row.
To tune a signal generator with
a touch-tone phone, connect the
generator output to the two mic-
rophone terminals in the phone
handset, press 1 and 2, and tune
generator until "beats" stop.
Generator is now putting out 697.

on boxing, the Bell System Technical Journal, in 1960 or in 1961, put out
an article called Multifrequency signaling systems.
You might find it in

it if an astute YiPPler would go there armed with a razor blade, and after
