33-Number Memory Tone Dialer/Red Box Conversion
===============================================
by Cajun

I'm not going to throw a bunch of technical crap in your face for this
conversion.  All you need for the conversion is a Radio Shack 33-Number
Memory Tone Dialer (Part 43-146), a 6.5536 MHz crystal (it's
approximatly 1/2 x 1/2 x 1/8 in.), a soldering iron, some needle 
nosepliers, some small wire cutters, a small phillips screwdriver, and 
a little patience.First, remove the battery cover from the back of the 
tone dialer.  You should be able to locate 4 screws beneath the cover, 
and there should be two near the top of the tone dialer (back side).  
Remove these screws and take notice which screws came from where.  
Set the screws aside and CAREFULLY wiggle the back of tone dialer away 
from the front, DO NOT YANK THEM APART!  This will snap the speaker wires, 
and that would suck. Locate the old crystal (it looks like a small, silver 
can of Pringles).  Try to loosen the crystal with the pliers, if this 
doesn't work, melt the glue with the soldering iron and pull the crystal 
upright.  Cut the leads of the crystal with the wire cutters and save the 
crystal, you might want it again in case you get tired of your red box.  
Take the 6.5536 MHz crystal and solder it in place of the old crystal.  
Try to make the leads as short as possible, but it's ok to leave a little 
extra to use to move the crystal around before you put the dialer back 
together.  The idea of keeping the leads as short as possible is that 
the longer the leads are, the smaller the accuracy of the tones produced 
(it takes longer to travel over extra-long leads, makes sense huh?).  
The new crystal should be soldered now.  Nowcomes the frustrating part.  
When the tone-dialer was designed, it was made as compact as possible,
thus, the larger crystal takes up more room.  Fit the two pieces of the
tone dialer together and press them together firmly.  While holding the
pieces together, start each screw into it's special little hole, and fasten
just enough that you can let go of the tone-dialer.  Finish putting the
screws in by tightening the middle screws first (the ones in the middlerow 
if the tone dialer was sitting tallways).  Go ahead and tighten the
others now, in no particular order.  Pop the batteries into the tone-dialer
(now red box) and place the battery cover back on the unit (I assume you
already have batteries, AAA in case you don't).  Turn the unit on.  The key 
you use to produce the coin tones is the star.  1 tone is a nickel, two 
tones a dime, and five tones a quarter.  It's probably agood idea to store 
each one of the different tones on the special P#memory keys, but it's 
probably easier just storing the tones for a quarter. The 43-146 offers 
an option to pause after a digit or symbol is entered, sohere's a tip to 
make life easier.  Store the coin tone for a quarter into P3. Now go into 
store mode and press memory.  Press P3 once, followed bypressing PAUSE 3 
times, then P3 again, then PAUSE 3 times.  Now press memory again.  Press P2.  
P3 now plays the coin tone for a quarter, and P2plays the sequence for 2 
quarters.  When you use your red box (that's right, it finally a red box), 
make sure the rubber ring around the red box speaker is directly over the 
mouthpiece of the phone, and preferably upright.  Dial the long distance 
number first to find out how much you need to fake-in, and press the 
appropriate keys on your red box.  Take your time when you enter the keys.  
The fascist operators are listening and will come on the phone if something 
goes wrong.  If you take your time though, you should have no problems. 
Unfortunatly, this red box will not work on local calls (but the subject 
is being studied!).

Happy phreaking!!!!
