NOW ON TO THE TWO JACK VERSION.
TWO JACK VERSION...
BACK TO SHEET 1, IC21/22.  CUT THE TRACE FROM IC21, PIN 3 TO IC22,
PIN 4 BEING CAREFUL OF WHERE YOU CUT IT.  THIS IS ONE PLACE THAT YOU
CAN CUT WRONG.  HOOK THE ARMATURE OF A SWITCH SECTION TO IC22, PIN
4.  THEN HOOK THE N.O. CONTACT TO IC21, PIN 3.  MAKE SURE THAT THE
PREVIOUS SWITCH SECTION N.C. CONTACT STILL GOES TO PIN 3 ALSO.  THE
N.C. CONTACT WILL THEN GO TO AN ADDED JACK FOR TTL DATA INPUT TO THE
AMT-1.
LOCATE SHEET 3 AGAIN AND ICS 16 AND 3.  CUT THE TRACE FROM IC16 PIN
3 TO IC3 PINS 12/13.  THE ARMATURE OF A SWITCH SECTION GOES TO IC16,
PIN 3.  THE N.O. CONTACT GOES TO IC3, PINS 12/13 WHICH IS THE SAME
POINT AS LK1 HOLE A AND THE PREVIOUSLY INSTALLED N.C. SWITCH
CONTACT.  HOOKING THE N.C. CONTACT TO ANOTHER SEPARATE TTL OUTPUT
JACK WILL FINISH THIS PART OF THE MOD.
FOR THE ADDED TTL JACKS, I USED A COUPLE OF RCA (PHONO) JACKS.  THEY
ARE EASY TO MOUNT AND USE.  BE SURE TO LABEL THE INPUT AND OUPUT SO
YOU DONT GET THEM MIXED UP.
