A. DICKENSON AND [CHARLIE YOUNG]..NOTE F
ROM CHARLIE YOUNG:..I ADDED A SECOND CHI
P TO MY C64C FOLLOWING MARK'S INSTRUCTIO
NS AND A C64.SCHEMATIC. ONE OF THE CHIP
S THAT MARK REFERRED TO DOES NOT EXIST I
N MY.COMPUTER. THIS UPDATED SET OF INST
RUCTIONS SHOULD WORK FOR ANY C64 OR C128
.COMPUTER...THIS IS NOT A PROJECT TO BE
TACKLED BY THE SQEAMISH OR PEOPLE WHO AR
E DEATHLY.AFRAID OF OPENING THEIR COMPUT
ER JUST TO TAKE A PEEK INSIDE. [IF YOU
WERE.ONE OF THEM, YOU WOULD BUY THE STER
EO CARTRIDGE FROM CMD]. HOWEVER, THE.IN
STRUCTIONS ARE FAIRLY SIMPLE. IF YOU ME
SS SOMETHING UP, IT WILL PROBABLY.BE THE
SOUND CHIP. HOPEFULLY THE REST OF THE
COMPUTER WOULD NOT BE AFFECTED...NO LIAB
ILITY IS ASSUMED WITH RESPECT TO THE USE
OF THE FOLLOWING INFORMATION..IN OTHER
WORDS IF YOU SCREW-UP TRYING TO INSTALL
THIS MODIFICATION, THEN.IT'S YOUR RESPO
NSABILITY. YOU DO THIS AT YOUR OWN RISK
!!!!..OVERVIEW..YOU WILL PIGGYBACK A SEC
OND SID CHIP TO THE ORIGINAL. ALL DATA,
ADDRESS, AND.POWER PINS WILL BE SOLDERE
D TO THE ORIGINAL CHIP. SEVERAL OTHER P
INS WILL.NOT BE SOLDERED TO THE ORIGINAL
, SO PAY ATTENTION TO THE INSTRUCTIONS..

FIND ON THE BACK OF YOUR. STEREO)...
HOW TO DO IT..PRINT THESE INSTRUCTIONS,
AND CHECK OFF EACH STEP AS YOU DO IT...D
ISCONNECT THE POWER SUPPLY. TAKE THE CO
MPUTER CASE APART. REMOVE THE.KEYBOARD.
TAKE OFF THE TOP SHIELD. YOU DO NOT H
AVE TO REMOVE THE MAIN.BOARD. IF YOU CO
NNECT THE POWER SUPPLY TO CHECK VOLTAGES
, DISCONNECT IT.BEFORE DOING ANY SOLDERI
NG...YOU SHOULD GROUND YOURSELF WITH A S
TATIC GUARD WRISTBAND (SUCH AS WHAT RADI
O.SHACK SELLS). EVEN THOUGH THE CHIP IS
QUITE DURABLE, JUST THE RIGHT STATIC.DI
SCHARGE CAN RUIN ALL OR PART OF THE SID
CHIP.....PAGE 1
ADD 2
ND SID....NOTE WHICH WAY THE ORIGINAL SI
D CHIP IS INSTALLED. THE NOTCH PROBABLY
FACES.THE BACK OF THE COMPUTER...REMOVE
THE ORIGINAL CHIP. PULL IT STRAIGHT UP
USING A CHIP PULLER OR PRY.WITH A SMALL
SCREWDRIVER AT BOTH ENDS. PUT THE SECO
ND CHIP IN THE SOCKET AND.TRY IT OUT. Y
OU WILL HAVE TO REINSTALL THE KEYBOARD T
O DO THIS, BUT YOU DO.NOT HAVE TO PUT TH
E CASE BACK TOGETHER. IF YOU BOUGHT THE
CHIP FROM.GRAPEVINE, IT MAY BE BAD -- E
SPECIALLY IF IT HAS PINS MISSING...IF TH
E SECOND CHIP IS GOOD, THEN YOU ARE READ
Y TO BEGIN PIGGYBACKING...HERE IS A SHOR
T EXPLANATION OF THE WAY PINS ARE NUMBER
ED ON AN IC CHIP. ON.ONE END OF THE IC
YOU SHOULD FIND A LITTLE NOTCH. LOOKING
AT THE CHIP WITH.THE NOTCH AT THE TOP T
HE NUMBERING GOES THIS WAY. THE UPPER L
EFT CORNER OF.THE CHIP IS PIN 1 AND THEY
ARE NUMBERED CONSECUTIVELY, COUNTER-CLO
CKWISE.AROUND THE CHIP. SOME CHIPS DO N
OT HAVE A NOTCH IN ONE END, BUT INSTEAD
A.DOT IS PLACED IN ONE OF THE CHIP CORNE
RS TO DESIGNATE THAT PIN 1 STARTS IN.THA
T LOCATION... NOTCH.

AND CUT THEM OFF OF THE 6581 SID CHIP..T
HESE ARE FOR THE TWO ANALOG (PADDLES) AN
D ONE AUDIO INPUT LINES. THEY WILL.CAUS
E PROBLEMS IF CONNECTED AND SINCE THEY W
ILL NOT BE USED IT IS BEST TO.REMOVE THE
M...NOW BEND OUT PINS 1, 2, 3, 4, 8, 27.
..CHARLIE RECOMMENDS MAKING A HEAT SINK.
FIND A THIN NARROW STRIP OF METAL.THAT
IS LONGER AND NARROWER THAN THE SID CHI
P. COVER THE TOP OF THE ORIGINAL.CHIP W
ITH A THIN LAYER OF HEAT SINK GREASE. L
AY THE STRIP ON TOP OF THE.ORIGINAL CHIP
. YOU MIGHT FASTEN IT WITH A SMALL SPOT
OF GLUE TO MAKE SURE.THAT IT DOES NOT M
OVE AND SHORT THE PINS LATER. NOW SMEAR
THE BOTTOM OF THE.SECOND CHIP WITH A TH
IN LAYER OF HEAT SINK GREASE. MAKE SURE
THE NOTCHES.FACE THE SAME WAY, AND MAKE
THE SANDWICH. BEND THE HEAT SINK STRIP
OVER THE.END AND TOP OF THE TOP CHIP.
YOU WILL WANT THIS STRIP TO TOUCH THE TO
P.SHIELD WHEN YOU REPLACE IT...PREPARE T
O SOLDER. YOU WILL BE SOLDERING SOME PI
NS OF THE TOP CHIP TO THE.BOTTOM CHIP...
SOLDER ONE OF THE 2,200PF CAPACITORS TO
PINS 1 AND 2 THEN SOLDER THE OTHER.2,200
PF CAPACITOR TO PINS 3 AND 4. THE CAPAC
ITORS CONTROL THE UPPER AND.LOWER FREQUE
NCY RANGE OF THE SID CHIP...NOW SOLDER T
HE REMAINING PINS (EXCLUDING THE ONES WE
HAVE BENT OUT AND ALSO.REMOVED 1, 2, 3,
4, 8, 23, 24, 26 AND 27) TO THE ORIGINA
L SID CHIP. YOU MAY.HAVE TO BEND THE TO
P CHIP PINS INWARD JUST A LITTLE FOR THE
M TO GET A GOOD.GRIP ON THE BOTTOM CHIP.
BE VERY CAREFUL NOT LEAVE THE SOLDERIN
G IRON ON THE.CHIP TOO LONG AS YOU COULD
RUIN BOTH SID CHIPS...NOW THAT YOU HAVE
THE CHIPS SOLDERED TOGETHER PLACE THE S
ID CHIPS BACK IN THE.SOCKET.....PAGE 2
ADD 2ND SID.....DESELE

CHIP IS INVISIBLE TO THE COMPUTER -- THE
CHIP.SELECT PIN STAYS HIGH ALL THE TIME
WHICH KEEPS THE CHIP FROM RESPONDING TO
.ANY READS OR WRITES. IF YOU TURN THE S
WITCH OFF WHILE CHIP 2 IS GENERATING.SOU

UND. -...I RAN THE 12 VD
C IN SHIELDED CABLE TO REDUCE NOISE. YO
U CAN GET 12 VDC FOR.THE TRANSISTOR FROM
PIN 28 OF THE SID CHIP. IT IS ACTUALLY
9 VOLTS IN THE.C64C. USE THE SHIELD TO
CONNECT GROUND FROM THE COMPUTER TO THE
PERF BOARD..PUT SOME SPAGHETTI (EMPTY I
NSULATION) OVER THE BARE SHIELD WIRE SO
THAT IT.WILL NOT SHORT OUT ANYTHING IT T

VARIABLE...ADDRESS..THE ADDRESS OF THE
SECOND CHIP IS $DF00 HEX 57088 DECIMAL.
THE ADDRESS OF.THE ORIGINAL CHIP IS $D5
00 HEX 54528 DECIMAL. ANY BASIC PROGRAM
THAT USES.THE SID STARTING ADDRESS AS A
VARIABLE, CAN BE EASILY CHANGED TO ACCE
SS THE.SECOND CHIP. EXAMPLE:..10 S=5452
8. CHANGE TO:.10 S=57088..TRY RUNNING T
