WELL, WHAT YE OLDE FUCK. HERE ARE THE SCHEMATICS. I DON'T THINK YOU CAN
GET BUSTED JUST FOR KNOWING HOW TO MAKE COMPARATERS, SO I WILL JUST SAY NOT
TO USE THEM ON ANYBODY ELSE'S PHONE. IF YOU DO, I'M NOT RESPONSIBLE FOR
WHAT GOES DOWN. I REALLY DON'T CARE BUT THAT'S HOW IT GOES...
OK... NOW THAT THINGS ARE COOL, I WILL GIVE YOU THE SCHEMATICS...
BUT FIRST... AS EVERYONE KNOWS, TEXT-SCHEMATICS SUCK SHIT. THAT BEITH WHY
I HAVE DEEMED IT NECESSARY FOR SOMEONE TO CREATE A STANDARD ELECTRONIC
CHARACTER SET. MAYBE I'LL WORK ON IT BUT IF SOMEONE COMES UP WITH ONE, ALL
HAIL THE MIGHTY CHARACER SET! MY IDEAS FOR ITS CONSTRUCTION ARE LIKE HAVING
STANDARD CHARACERS REPRESENT ELECTRONIC SYMBOLS LIKE THIS...
'Q' = LEFT SIDE OF HORIZONTAL RESISTOR
'E' = RIGHT SIDE OF HORIZONTAL RESISTOR
'R' = HORIZONTILE CONNECTION
'T' = VERTICLE CONNECTION
'Y' = HORIZONTAL CAPACITOR, NON-POLARIZED
ETC, ETC, ETC...
ANYWAY, TIS BUT A THOUGHT. IT COULD BE DONE USING HRCG WITH DOS TOOLKIT AS
EVERYBODY HAS THAT, OR WHATEVER, BUT THE THING IS TO KEEP IT STANDARD FOR
EVERYBODY! IF THIS CATCHES ON, MAYBE PEOPLE WILL PASS ESS DIGITAL DESIGN
SPECS OVER THE MODULATOR...

YEAH, SO THE ABOVE BULLETIN WAS THE SCHEMATIC. NOW FOR AN EXPLANATION. AS
THE THEORY OF THIS THING WAS MENTIONED IN A PREVIOUS BULLETIN, I WON'T
CONCERN MYSELF WITH THAT. FIRST A PARTS LIST...
RESISTORS... 47K OHM, 10K OHM, 1K OHM.
POTENTIOMETERS... 50K OHM TRIM POT
CAPACITORS... 0.1 UF
SEMICONDUCTORS... PNP - 2N3906 TRANSISTOR, NPN - 2N3904 TRANSISTOR,
1N4005 DIODE.
BATTERY... ONE 6 VOLT OR FOUR 1.5 VOLT, A SWITCH WOULD BE
NICE...
RELAY... I'M USING A LITTLE BLUE 4.5 VOLT (I THINK) RELAY
WITH DOUBLE POLE, DOUBLE THROW CONTACTS. IT'S IN
A DIP ARRANGEMENT AND I CAN'T REMEMBER THE RADIO
SHACK NUMBER...
MISC... VARIOUS SIZES OF JACKS FOR INTERFACING THE TAPE
RECORDER, BATTERY, TELEPHONE LINE, ETC.
I BUILT THIS THING FOUR TIMES ON A BREAD BOARD AND TWICE ON A PC BOARD
BEFORE I GOT IT TO WORK TO MY SATISFACTION. I SUGGEST YOU BUILD IT
