MOD UPDATE
To use the Troubleshooter, you need to remove the custom microprocessor chip and insert a 40-pin IC socket. A low profile,
dual leaf type socket, such as 3M part number 4840-6004-CP, is recommended.
The controller chip used in this board is very rare and is no longer available, so you must be very careful when you remove it.
Use a low wattage soldering iron and a desoldering tool to remove the solder from the IC pads. Do not heat the pad for too long
or it will be damaged and lift off the board. Carefully wiggle each lead with a needle-nose pliers to free it from the pad. Gently
pry the IC from the board using a small screwdriver at each end. Do not apply excessive force or you will break a pin.
Insert the 40-pin IC socket with the notch facing up. After soldering the pins, you can remove the residual flux using 91%
Isopropyl alcohol.
TIP ... A Mod Update was issued for CCC board # 6-09971-01, wire jumper W222 was changed to a 220 Ohm 1/4W resistor.
Some board failures are caused by solder joint fractures at the connector
pins. This happens when a connector is inserted, which creates pressure
on the pin, causing it to push through. The foam padding behind the circuit
board was used to relieve this pressure, but in many cases, is either
deteriorated or missing altogether. It is best to remove the old solder and
resolder these connector pins then clean off the residual flux. You can
replace the foam padding with a 1/4" thick rubber mouse pad.
BROKEN SOLDER
Two circuit board types were produced. The first board was # 6-08871-01
which used the Rockwell 6500 microprocessor IC, the next board was part
# 6-08871-04 and used the Mostek 3870 microprocessor. These chips are
not interchangeable because of the pinout differences. It is also important
to know this when using the Troubleshooter board. You must use the
proper position, either the U2 6500 CCC-01 or U1 3870 CCC-04.
PLUGGING IN TROUBLESHOOTER BOARD
For 6-08871-04
For 6-08871-01
At the bottom side of the tester board are two 40-pin IC sockets.
Two 20-pin strip headers will be inserted into one of these
sockets. The board under test here is part # 6-08871-01 which
uses the U2 socket position. Gently press the pin strip into the
socket, being careful not to bend the pins.
Now insert the tester board
into the IC socket. Make sure
the pins line up with the
socket then gently press
down.
On the PC Serial cable, plug
the 6-pin white connector end
into P-103 on the Central
Control Computer board.
PC Serial Port
The 9-pin DSUB connector
end plugs into your PC's serial
port connector.

If you don't have a serial port,
then you need to get a USB to

STARTING UP THE TROUBLESHOOTER PROGRAM
When the Central Control Computer board is powered up, the tester board LED should light and start up message displayed.
If the tester board LED is not on ...
Did you use the correct U1 or U2 position ? Does the socket have 5-volt power ? Is the RESET signal 2-volts or higher ?

STROBE Commands
The STROBE commands activate 1 of 10 output signals, in a stationary state (high or low), so you would only need a voltmeter
to do circuit troubleshooting. The "STROBE OUTPUTS" page shows the voltage readings for each STROBE state. The 1's and
0's display the current logic state of the RETURN input signals. A logic "0" indicates an active or on signal. The "RETURN
INPUTS" page shows the RETURN signal map for each of the associated STROBE signals.
For example, if STROBE7 is selected (pressed "7" on the PC keyboard), the following will display:
CMD>7
STROBE7:
1 1 1 1 1 1 1 1
The STROBE7 output signal is continuously held active and the RETURN signal state displayed. Any change of the RETURN
signal state will cause a display update. The following display shows this when a quarter was deposited.
A review of the RETURN signal map (RETURN INPUTS page) shows this signal or bit position to be the "25¢ Coin Switch".

Run All Tests (Memory and Mechanism)
This is a continuously running test that checks RAM memory and Mechanism operations.
For the memory test, the "RAM Retention Data" may fail on the first time because the check pattern has not been written. This
check pattern is used to verify the battery backup circuit. After the first time through, turn the power off, wait about 5-minutes,
turn the power on then run this test. The "RAM Retention Data" test should pass.
For the mechanism test, the record magazine is rotated then stopped at record number 50. During the rotation, pulse
measurements are recorded and displayed for the HOME and INDEX optical signals. When record 50 is reached, it is
transferred to the turntable and played. The "A" and "B" side is toggled at each record play cycle. The Pass Number count is
displayed after each cycle. Every test step position is displayed.

RAM Memory Test
Performs all RAM Memory tests. Stops when a memory error is detected and displays the error result. The LED displays will
show random patterns during the memory test. In the example below, pin 11 on Z109 (data in, bit 2) was intentionally lifted off
the circuit board to create an error condition. ADDR is memory address being tested, WAS is the data pattern that was read
and SB is the data pattern that it should be. Z109 is the upper 4-bits, Z114 is the lower 4-bits.

Show All Active Signals (as Text)
Displays all active or on signals then enters Interrogator Mode. This is used to identify what signals should be or should not be
active (such as a stuck push-button switch). It can also be used to verify the pricing board configuration settings. The (CR###)
display is the diode designation number associated to that signal.

MECHANICAL SWITCHES, PROGRAM DIODES & CARDS
All other switches, including coin and keypad, use the same
circuitry, a switch, the appropriate STROBE / RETURN
signals and a diode.
Programming cards and diodes use a fixed circuit trace
instead of a switch.
The matrix above shows the STROBE / RETURN correlation
of all signals.
Active or ON signals
are valid between
4 to 8 volts.

-04 BOARD
MEMORY BACK -UP BATTERY / BATTERY VOLTAGE DETECTOR
The original back-up battery is most likely "very old" and will cause
acid damage if leaking (green corrosion). You can replace it with a
dual AAA battery holder (Mouser 122-0421-GR), double-side foam
tape and new rechargeable Nickel-Metal Hydride AAA batteries.
TIP ... Use a cotton swap with household ammonia to remove the
green corrosion, afterwards, rinse and blow dry.
