Thanks to Durkatlon for the translation to English.  The article comes courtesy
of Hacktik Magazine issues #16 an #17.  If you can use it, cool, if not, skip
on to the next article.  This is the form in which I received the file.  I have
not tested or used this, as yet.  Guess that gives me something for another
article.

DEMON DIALER SPECS
------------------
The chip contains a blue-box, DTMF dialer, C4 and ATF1 tonegenerator and much
more.  Just about the whole stratum of phone-phreak knowledge has been
incorporated into this device and because the chip contains an amount of RAM
memory, new signalling systems can be built in.  The ideal tool for today's
phone-phreak.

In the sequel is a list op all the abilities of the MC68HC705C8P/DD, as it is
officially called.  Furthermore a small overview of what it takes to put a nice
little box around it.


THE MC68HC705C8P/DD
-------------------
It's a Motorola processor of the 68705 kind, programmed by us.  It only
requires an additionla matrix keyboard of 3 by 4 keys, a couple of resistors,
and a D/A convertor with a filter.  Hook it up to 5 Volts and there ya go, da
perfect phone-phreakin' tool.

If you power up the chip it's just a DTMF dialer, and if you don't enter the
right code that's exactly what it will stay.  Only after the code's been
entered (which by the way is a different one for each chip) you can switch to
the other modes:

o DTMF, RedBox, C3, C4, C5, R1, R2 (both directions) and ATF1 modes built-in.
  2 new sistems can be programmed later.

o Guard banding:  Every tone or double-tone can be combined with a third
  frequency.

o Advanced Macro capabilities. Macro nesting is possible.

o All settings are stored in RAM if the machine is switched off.

o For DTMF, C5 and C3, both space and mark timing are possible.

o C3 has programmed space and mark frequency and is thus useable as a general
  purpose signalling system.  Furthermore pulse-dialing is possible through a
  relais-control-signal.

o User-Defined-Modes can make use of variable timing and frequencies.

o Tone-sweep and the ability to set starting frequency and step-size.  Also
  useable for continuous sweep.

o Phone number scan with variable step size for all signalling systems


CONSTRUCTION
------------
The MC68HC705C8P/DD is at the heart of a do-it-yourself bluebox, but a number
of elements you will have to build yourself.  You're going to have to connect
the matrix keyboard as well as a simple D/A convertor and a speaker.  The total
cost of hardware to be added shouldn't exceed the amount of 50 guilders.  On
the flip page is the schematic [heheh..] and shipped with the chip is a
comprehensive set of datasheets and a software manual both in English and
Dutch.  The hardware description pays more attention to the D/A convertor,
filter, keypad etc.  than does this short article.  Furthermore it contains
schematics to make the device run on 3 volts and drive an 8 ohm speaker.


HOW TO OBTAIN THE CHIP?

The chip costs 250 guilders, including shipping, a Dutch and English manual of
the software and a detailed description of the hardware.  Pay the mailman.  For
more information call +31-20-6001480.

*** NOTE: $1.00 US ~ 1.80 guilders
