Well, its now October, and here in Edmonton it has started to get cold,
and the trees are starting to lose their leaves. Thanksgiving has
passed, and Halloween is coming up! So, you'll notice
the C.A.T.S. logo looks sorta like blood is dripping from it. Well
its suppost to look that way, and the issue has been halloweened up.
Anyways, onto issue #2!
For those of you who missed the CBC open house, too bad for you!
It was very cool! You got to see how a TV station and a radio
station works, steal some disks and watch the football game. Man,
seeing all that makes me want to construct a snow box and start
a pirate TV station...
Anyways, in other news, our web page is up. It is at:
http://www.tripod.com/members/~catslash/index.html
It is pretty crappy right now and there is an FTP problem so you
can't really download any issues yet, but it will be fixed and
looking better soon! So, in your spare time, visit it and see.

Hello all you hackers and phreakers out there, here is
the latest buzz from some high schools, here on the
connection corner:
Information posted accurate of sept 16/ 96
From M.E Lezerte: News states that people may be
transferring from other schools and into lezerte, (information not
confirmed).
From Victoria composite: Information reportedly pulled from
teacher newsletter stating that science teachers may be
planning to do their own rendition of the Villiage people's song
"Y.M.C.A" . info confirmed.
From Eastglen: Rumor has it that there may be a gay teacher,
this information is not for me to confirm, but for you to check
out.
Well thats good for a start, join me next month for the
connection corner ! Note: information was obtained by the use of
private sources, if you would like to assist me please leave a message
for cats member:
Jebidiah care of "the loony bin bbs".

/o o\ Using you Mac For tone generation /o o\
\ || / \ || /

While browsing through the C.A.T.S library, I ran across this file
from (I think) the MACHACK FAQ. I figured it would be a good
idea to throw this in the magazine for people like us who own
macs. Take not that we did not write any of this.
The translation may be a little fucked up, the file is best
viewed with a 9pt font.
AUDIO LINKS
~~~~~~~~~~~
By Mr. Upsetter
It all started with my Macintosh...
Some time ago I had this crazy idea of connecting the output from the
audio jack of my Macintosh to the phone line. Since the Macintosh has built in sound generation hardware, I could synthesize any number of useful sounds and play them over the phone. For instance, with a sound editing program like SoundEdit, it is easy to synthesize call progress tones, DTMF and MF tones, red box, green box, and other signalling tones. So I set out to do exactly this. I created a set of synthesized sounds as sound resources using SoundEdit. Then I wrote a HyperCard stack for the purpose of playing these sounds. Now all I needed was a circuit to match the audio signal from the headphone jack of my Mac to the phone line.
How The Circuit Works
~~~~~~~~~~~~~~~~~~~~~
I designed a simple passive circuit that does the job quite well. Here is the schematic diagram.
+------+ T1 +------+
o-----| R1 |-----o------o--------(| |)-----| C1 |-----o-----o
+------+ +| -| (| |) +------+ |

jack +---+ +---+ (| |) +---+ line
-| +| (| |) |
o------------------o------o--------(| |)------------------o-----o
C1-.22 uF, 200V
D1,D2- 1N4148 switching diode
R1-620 ohm, 1/4W
T1- 8 ohm to 500 ohm audio transformer, Mouser part 42TL001
VR1-300V MOV, Mouser part 570-V300LA4
VR1 is a 300V surge protector to guard against transient high voltages.
Capacitor C1 couples the phone line to transformer T1, blocking the phone
line's DC voltage but allowing the AC audio signal to pass. The transformer
matches the impedance of the phone line to the impedance of the headphone
jack.
Diodes D1 and D2 provide clipping for additional ringing voltage protection
(note their polarity markings in the schematic). They will clip any signal
above 7 volts. Resistor R1 drops the volume of the audio signal from the Mac
to a reasonable level. The end result is a circuit that isolates the Mac
from dangerous phone line voltages and provides a good quality audio link to
the phone line.
Building and Using the Circut
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This simple circuit is easy to build (if you're handy with electronics). I
personally prefer to solder the circuit together. A length of shielded audio
cable with a 1/8 inch mono plug on one end should be connected to the audio
input end of the circuit. A standard RJ11 phone jack should be connected to
the phone line end of the circuit. Although this circuit will protect
against dangerous phone line voltages, it is best to disconnect it when not
in use. You just don't want to risk anything bad happening to your brand new
Quadra 900, right?
Once you have an audio link between your Mac and the phone line, the
applications are limitless. Use HyperCard's built-in DTMF dialing to dial for
you, or build a memory dialer stack. Talk to people with Macintalk. Play
your favorite Ren and Stimpy sounds for your friends. Play a ringback tone
to "transfer" people to an "extension". Build and use a set of synthesized
MF tones. Try to trick COCOT's with synthesized busy and reorder signals.
But Wait, There Is More...
~~~~~~~~~~~~~~~~~~~~~~~~~~
So you say you don't own a Macintosh? That is ok, because the circuit can be
used with other devices besides your Mac. You can use it with the 8 ohm
headphone output from tape recorders, radios, scanners, etc. You could also
probably use it with any other computer as long as you had the proper audio
D/A hardware and software to create sounds.
All parts are available from Mouser Electronics. Call 800-346-6873 for a

/o o\ More ED Tel News /o o\
\ || / \ || /
|||| --------------------------------------------------------- ||||
A lot has been going on this fall. Tellus has gotten rid of more
ED Tel stuff, so start collecting your ED Tel stuff. Rip the ED Tel
logo off a payphone. Keep all those stolen ED Tel matchbooks you
grabbed from open ED Tel vans (among other things) it may be valua-
ble some day. Tellus changed the AGT logo on the AGT Tower to a
Tellus logo, and has changed all the signs on the central dispatch
to Tellus as well. The ED Tel vans are repainted (and on the orange
ones re-decaled) to show the Tellus symbol. The only things not
changed are the ED Tel building's signs and the ED Tel Phone Exhange.
They even re-did all the recordings (like the "This number is not
in service" recordings to different wordings and voices.
Tellus has also removed a lot of payphones that were "abused"
by local customers. And, in case you haven't looked outside,
ED Tel/Tellus vans are everywhere. All of them have been rushing
around to prepare for the dissolving of ED Tel and AGT to become
Tellus (see last issue).
Unitel was also recently bought out by AT&T Canada. With
this, AT&T Canada is moving in, as a cellular service provider.
So you may notice AT&T station wagons rolling around too.They
carry little inside that is of use.
And finally the big news. The local company moving in to compete
with ED Tel/Tellus is Phone-a-rola (I'm assuming that's how to
spell it). They are from Ontario and will soon be moving into
Edmonton and another city in BC. They WILL install their own
lines, prior to what ED Tel says. They will have one advantage
now, since lots of people hate Tellus for moving all ED Tel's
operations to Calgary and having such shitty service. But, won't
it be fun to be able to choose who's service to phreak on!
More as it comes...

/o o\ Making Napalm /o o\
\ || / By: Jeriatrick \ || /
|||| --------------------------------------------------------- ||||
This article was origionally slated for issue 1 but was pulled for
a better article. I'm going to get it in now however...
We, the elite are dying so fast that most people don't even know
how to make this wonderful toy.Lets hope some new Anarchists are
reading this and will learn...
To make Napalm get an old bowl or container.Put some gas in it.
Throw in some styrofoam. The gas dissolves the styrofoam into
a syrupy greyish, mixture.Fill it with styrofoam (it is full
when the gas won't dissolve anymore styrofoam, and the styrofoam
sits on the top.). Put some somewhere and light it.It burns
real long...and real good...
A NOTE: Don't keep it in a plastic container too long. They tend to
dissolve.
ANOTHER NOTE: If you leave it in an open container, the napalm
will become less effective (I think the gas evaporates).
Have fun playing with this stuff, it has multiple uses...

/o o\ News Paper Vending Machines /o o\
\ || / By: Jeriatrick \ || /
|||| --------------------------------------------------------- ||||
Want a free newspaper, at least for the comics? Try this when you
see one.
The coin return button is linked to the doors and coin slots on
these machines. To open them several ways can be used:
1. Hit the coin return button and pull down the door at the same time.
2. Do step one repeatidly (sometimes it takes several times)
This way opens quite a few machines.The Sun machines open easier
than the Journal and Financial Post ones. You have to get the
timing right on the hit-open but you may suceed. Some machines,
(as noted) will take several hits on the coin return button.
Do not take too many newspapers, or the newspaper company will
remove the coin-return button. If this dosen't work, remember
that the plexiglass window on the front gets pushed (or kicked)
in fairly easily!
So, start your paper mache project...
