IMPORTANT
NOTE
DO NOT plug in your new game yet.
Before you do anything to your game, we
recommend that you read SECTIONS I
and II of this manual completely. It will
not take more than a few minutes and it
may be very helpful.
I. Introduction
fright no matter where they are in the maze. This is
because they know that when she eats an ENERGIZER DOT it gives MS. PAC-MAN the ability to
eliminate them. However, she can ONLY eliminate
them for as long as they are blue.
MS. PAC-MAN is a one or a two player game. There
are three models: the “UPRIGHT”. “MINI”, and
“COCKTAIL TABLE”. When the two player mode is
selected on the Upright or mini model, the players
take turns at the controls to guide their player
through the game course. If you have purchased the
Cocktail Table model of this game, the rules of play
are the same. The only difference is that in the two
player mode of the Cocktail Table game, the picture
flips to face you when it’s your turn.
The ghosts will only stay blue for a few secondsafter
MS. PAC-MAN eats an ENERGIZER DOT. But they
do give a warning BEFORE they turn back to their
original colors - they start to flash.
As your skill level increases, the four
up their pursuit of MS. PAC-MAN and
for shorter and shorter periods of time
an ENERGIZER DOT until, in the
mazes, they do not turn blue at all.
When playing this game. you are in complete ,:ontrol
of MS. PAC-MAN. She will go wherever you tell her
to. And she just loves to eat dots. However, she
doesn’t like the four ghosts, BLINKY (red), PINKY
(pink), INKY(turquoise), and SUE (amber) because
they feel the same way about her as she does
about dots.

after she eats
high number
One bonus player (this is switch selectable) can be
awarded to you as you reach or pass a certain
preselected point value. The assigned point values
for all items that can be eaten are as listed in Figure 1.
BLilNKY,
PINKY, INKY, and SUE are four VERY
SMART ghosts. They move very fast and seem to
have a sixth sense which always lets therm know
exactly where MS. PAC-MAN is in the maze. They
never give up in their pursuit of her. One of their
favorite tricks is to divide and try to trap her between
them. You really nave to keep an eye on them.
Major New Features
A major new feature of your MS. PAC-MAN game is
that there are four different mazes with varying
numbers of exits and varying exit locations. The
mazes are generally more difficult than that of
PAC-MAN.
But MS. PAC-MAN can turn the tables on these four
ghosts for short periods of time during eact- maze.
All she has to do is let them get fairly close In their
pursuit of her and then eat one of the four flashing
ENERGIZER DOTS that every maze begirts with
(one close to each corner of the maze). When this
happens, it causes the four ghosts to turn blue with
Another major new feature is that the maze identifier
symbols move throughout the maze and are thus
more difficult to get.
l-l
Game Objective
The object of the game is to HAVE FUN and survive
as long as possible while constantly improving your
skrlls
and eating as many dots aid eliminating as
many ghcsts as you can. As you dcl this, each following maze will be harder and harder to complete

l Level the cabinet.
5. Open the cabinet and inspect the inside of the
game for any signs of damage. See Figure 2
l Also check to make sure all plug-in connectors
on the wire harness are firmly seated.
NOTE: ALL connectors or plugs are keyed so they
will only go together when all pins are pr*,perly
-lined up.
2. Voltage Selection:
Your game is designed to work properly on the
line voltage where you are located. Check your
line voltage with a meter to determine what its
value is Then check the power input wires to the
main power supply transformer on your game to
be sure they are connected to taps which correspond to your line voltage value.
Replug any connectors found unplugged. DO
NOT FORCE PLUGS ONTO CONNECTORS.
DO NOT FORCE PLUGS TOGETHER. If it
won’t go on easily, assuming the keys are
llnec! up, it either does not belong there or is
damaged
Make sure all pnnted circuit boards (l?C.B.‘s)
a r e f;rmly
sea?ed
i n t h e i r connecto,-s. S e e
Figure 2. These connectors arealso keyed. The
P.C.B.‘s
WII only go Into them one way vyithout
being damaged.
Note the locatlon of the game’s serlal number.
See Figure 2.
Check all major subassemblies to be sure they
are mounted securely These are called out in
Figures 2 & 3.

If the power input wires to the main power supply
transformer are not connected to taps wnich
correspond to your local line voltage, move teem
to the proper taps.
If the line voltage in your area fa!ls outside tne
upper or lower limits of the range of inputs
covered by the main power supply transformer.
DO NOT PLUG YOUR GAME IN until you have
talked with your distributor and/or service man
and obtained a solution to this problem. Otherwise you could damage your game.
3. Interlock and power ON/OFF switches. See
Figure 2.
. To help prevent the possibility of getting an
electric shock while working inside the game
cabinet, Interlock switches have been installed
at each cabinet access door (this DOES NOT
include the coin door in the Upright and M.ni
models).

2 The Play mode ends when your last MS. PACMAN has been eliminated. When thus happens,
“GAME OVER” IS wrrtten across tre center o‘the
monitor screen (below the “GHOST HOUSE”)
But v+rth
all four ghosts chasing her, It is not as
easy to eat the dots (without being elrmlnated by a
ghost; as It was earlier rn the game And SLINKY,
PINKY. INKY, and SUE are four VERY SMART
ghosts. For Instance, they will divrde up two, three.

3 The game consists of four different mazes. Each
maze has side exits. These vary in number and
location on each of the four mazes The mazes
contarn small dots in most of the passageways
plus four flashrng ENERGIZER DOTS (one near
each corner of the maze). MS PAC-MAN just
loves to eat the dots rn these passageways. Each
maze also has a’ GHOST HOUSE” at Its center maxImum capactty,
three ghosts at one time. Its
door IS on its top side (side farthest from player)
Howeber. 11 they get too close. MS PAC-MAN can
always eat one of tne fiashlng ENERGIZER
DOTS When this happens, It causes all four
ghosts to turn blue with frignt no matter where
2-10
they are in the maze. This is because they know
that when she eats an ENERGIZER DOT It gives
MS, PAC-MAN the abrhty to eliminate then..But,
she can ONLY eliminate them for as long as they
are blue And they wrll only stay blue for a short
perrod of trmc But the ghosts do give a warnrng
BEFORE
they turn back to therr orlgrnal colors they start to flash
Most of the above holds true in the “2 PLAYER”
mode also. But there are a few minor differer,ces.
TWO PLAYER OPERATION
The Upright, Mrni, and Cocktail Table models all
have two player operatron.
In the two player mode, the rules of play are the sare
as in the single player mode. There are some
addrtional rules, however.
When MS PAC-MAN ehminates a blue ghost, its
point value appears on the monitor screen at the
:)lace where the ghost was eliminated while at the
same trme berng added to your score. and the
ghost disappears - all except for its eyes. The
eves oo back to the “GHOST HOUSE” whe,-ethev
get another body of theirorrginal color. Thisdone,
they leave the “GHOST HOUSE’ agalr ard take
up their pursuit of MS. PAC-MAN once more.
In the Upright and Mm models, the players mtist
take turns at the controls.
In the Cocktail Table model, each player has his
own set of individual controls. The picture wrll flrp
to face you when it is your turn.(When it IS not
your turn, your set of controls will have NO effect
on the game.)
‘When she eats the last dot of any particular maze:
all movement stops Immediately, the maze
flashes, and the next maze aooears. All the crlavers
are in the new maze when’ii appears. The word
“READY”’ IS also there- right below the”GHOST

“READY”’ disappears and play begins.
You MUST eat all the dots in any particula’

Your turn lasts unkl one of the ghosts elkmrnates

Introduction
NO GAME CREDIT
The most common problems occur rn harness
components such as the coin acceptor, player controls, interconnecting wiring, etc. The TV monitor
and PCB computer cause their share of problems
too, but not as much as the harness and Its component parts TV monitor troubleshooting will not be
covered here because it is covered in that sea:tion
of
this manual.
As you already know, the PC6 computer is a
complex device
with a number of different c:ircuits.
Some circuits remain basically the same among
games, but overall therearea great many differences
between them. PCB troubleshooting procedures,
therefore, can be lengthy and will differ greatly
among games. However, some basrc
Z-80 CPU
informatron is involved It- this section.
For example, your prospective player Inserts
his
quarter and IS not awarded a game. The ‘rrst Item to
check is if the quarter is returned. If the quarter IS
returned. the malfunction most certarniy lres rn the
coin acceptor Itself. First, use a set of test coins tooth
old and new) to ascertarn :hat the player’s coin is not
undersize or underweight. If your test corns are also
returned. coin acceptor servicing IS indicated. Generally, the cause of this particular problem is a
maladjusted magnet gate. Normally, this WII mean
slightly closing the m&net gate a little by turnrng the
adjusting screw out a bit (see section on corn
acceptor for more details).
If the quarter is not returned and there IS no game
credit, the cause of the malfunctron may be in one of
several areas. Frrst try operating the coin return
button, if the coin is returned, the problem is most
likely in the magnet gate. Enlarge the gap according
to the coin acceptor service procedures If thus does
not cure the problem, remove the coin acceptor.
clean it and perform the major adjustment
procedure.
General
Suggestious
If the trapped coin is not returned when the w per
lever IS actuated, you may have an acceptor lammed
by a slug, gummed up with beer, a jammed corn
chute, or mechanical farlure of the acceptor mechanism. In thus case, frrst check for the slug tha: will
gerlerally be trapped against the magnet If so
srmply remove the slug and test the acceptor. If the
chLlte is blocked, remove the acceptor and remove
the jammed coins If there is actual fa!lure of the
acceptor, remove the unit and repair as Ihdrcated rn
the corn acceptor service procedures.
The first step in any troubleshooting procedure is
correctly identrfyrng
the malfunctron’s syraptoms.
Tills Includes not only the circuits or features malfunctroning, but also those still operatronal A carefully trarned eye will pick up other clues as well. For
instance, a game rn which the computer functions
fail completely just after money was collected may
have a quarter shorting the PCB traces. Often, an
experienced troubleshooter will be able to spot the
cause of the problem even before opening the
cabinet.
If the corn is making Its way through the acceptor
(that is, falling into the coin box), yet there is still no
game credit. you either have a mechanical farlure of
the coin switch or electrical failure of the corn ard
credit circuits. Tne frrst place to begrn IS bychechrng
the coin switch. Most of these switches are the
make/break variety of micro switch. whrcr. IS
checked by testing for continuity between the NO,
NC, and C terminals. When not actuated. the NCand
C terminals should be continuous and the NO
terminal open When operated. the NO and C
terminals should close and the NC should be open. If
the coin switch checks out, examine the connectlens
to the terminals to makesurothere isgood contact If
necessary. use the continul:y tester and check 1,071
the terminal lug on the switch to the assocrated PCB
trace This will tell you If there is a cont!nuous lineall
the way to the credrt circuit.
After all the clues are carefully considered, the
pcsstble malfunctronrng a r e a s c a n b e narrowed
dcwn to one or two good suspects. Those areas can
be examined by a process of elimination Lntil the
cause of the malfunction IS discovered

connectors. but do not allow them to touch. If
necessary insulate them with small pieces of electncal tape Then, connect your VOM across the
terminals of the fuse block (all electrrcal power shut

normally fluctuates a certain amount during
Ithe day as the total usage varies. Peak usage times
occur mainly at dawn or dusk. so If your machine’s
malfunctron seems to be related to the time of day,
this may be a factor. A large load connected to the
!same line as the game (such as a large &r conditioner or other device with an exceptionally large
motor) may drop the line voltage signrficaitly when
istatIng up This drop can result in an intermittent

locatron wiring, plug, or line cord may also cause a

RFSH
(Refresh)
Output, active low. RFSH indicates that the lower 7
bits of the address bus contain a refresh address for
dynamic memories and the current MREQ signal
should be used to do a refresh read to all dynarmc
memories
(Address Bus)
Trl-state output, active high A,+,, constitute a 16bit address bus. The address bus provlces the
address for memory (up to 64K bytes) data exchanges and for I/O device data exchanges. I!0
addressing uses the 8 lower address bits to allow the
user to directly select up to 256 input or 256 output
ports. 4 IS the least significant address bit. During
refresh time, the lower 7 bits contain a val!d refresh
address.
HALT
(Halt state)
Output, active low. HALT indicates that the CPU has
executed a HALT software instruction and IS awaiting either a non maskable or a maskable interrupt
(with the mask enabled) before operation can resume. While halted, the CPU executes NOP’s to
maintain memory refresh activity.
Do-b
(Data Bus)
Tri-state Input/output, active
high. Do-D7
constitute
an 8-bit bidirectional data bus The data bus is used
for data exchanges with memory and I/O devices.
WAIT
(Wait)
Input, active
low. WAIT Indicates to the Z-80 CPU
that the addressed memory or I/O devices are not
ready for a data transfer. The CPU continues toenter
wait states for as long as this signal is active. This
signal allows memory or I/O devices of any speed to
be synchronized to the CPU.
(Machine Cycle one)Output, active low. M, indicates that the current
machine cycle is the OP code fetch cycle of an
instrliction execution. Note that during execution of
2-byte op-codes, m is generated as each 03 code
byte is fetched. These two byte op-codes always
begin with CBH. DDH, EDH or FDH. E also occurs
with IORCI
to indicate an interrupt acknowledge
cycle.
INT
(Interrupt Request)
Input, active low. The Interrupt Request signal IS
generated by I/O devices. A request will be honored
at the end of the current Instruction if the Internal
software controlled interrupt enable flip-flop (IFFY IS
enabled and if the BUSRQ signal is not active. When
the CPU accepts the interrupt, an acknowledge
signal (IORd during M, time) is sent out at the
beginning of the next instruction cycle. The CPU can
respond to an interrupt in three different modes that
are described in detail in section 5.4 (CPU Control
Instructions).
MREQ
(Memory Request)
Tri-state output, active low. The memory request
signal indicates that the address bus holds a valid
address for a memory read or memor)’ write
operation.
IORQ
(InpuVOutput Request)
Trl-state output, active low. The IORQ
signal indlcates that the lower half of the address bus holds a
valid I/O address fora I/O read orwriteoperatton.
An
IOHQ
signal is also generated with an Ml signal
when an interrupt is being acknowledged to indicate
that an interrupt response vector can be placed on
the data bus. Interrupt Acknowledge operations
occur during M, time while I/O operations never
occur during M, time.
NMI
(Non-Maskable Interrupt)
Input, negative
edge triggered. The non maskable
interrupt request line has a higher priority than INi
and is always recognized at the end of the current
instruction, independent of thestatus of the interrupt
enable flip-flop. NMI automatically forces the Z-60
CPU to restart to location 0066~. The program
counter is automatically saved in the externa!
stack so that the user can return to the program
that was interrupted. Note that contmuous WAIT
cycles can prevent the current instruction from
ending, and that a BUSRQ will overrlde a NMI

(HOW
and take them seriously. The more equipment you
have the better, but a low cost Volt-Ohm-Mllliameter
can often do the trrck. Here are the steps to take
to
use this section of your manual.)
I. Frnd the symptom that matches the problems
your monrtor has in the “SYSTEM - DIAGNOSIS” subsectron The diagnosis tells the
circuit or area the problem may be in and
possibly even the actual component causing It
Thrs sectron has been designed to simply fam lrarize
you with one of the more mystical components in
your game - the T.V. monitor. If you are an
electronics technicran who is quite knowledgeable
on the subject, you may decide to just go to the
schematics and start troubieshootfng the de’ective
monitor. But if you are like most people, a morlitor is
a TV. set, and that means a complex doo-dad that
means big buck repairs. Thus isn’t necessarrly so.
This section of the manual will acquarnt you wrth the
monrtor and could just help you repair It If you feel
adventurous enough to give It a try If you have any
knowledge of electrontcs, especially the usa o f a
voltmeter, the repairs you can make are asion shing.
Just keep in mind that ELECTRICITY CAN BE VERY
DANGEROUS, SO BE CAREFUL!!
2. Once you have the circurt that IS causing tne
trouble, read the “TROUBLESHOOTING” subsectron to learn the procedure for finding the
bad part.
3. Next, go to the schematfc
section and find the
schematrc that matches your monitor It may be
helpful to read the “DIFFERENCES BETWEEN
MONITORS” subsection if you are unsure of
which monitor you have. Use the schematrc to
see what parts are in me offendrng circuit.
That really IS all there is to it. Just remember that
there are some bizarre or rare symptoms ro;
covered, or that a monitor may have two or more
drfferent problems that only a genius the experrenced, or an experienced genrus can figure out. But
be patient, follow safety precautions, and remember
that there is also lrterature available from the monitor
companies through your drstributor or from Mioway
Manufacturing Company on request (There is a ioli
free number on the backsideof thefrontcoverofthe
manual.)
If you want to understand how a monrtor works, just
reatl the “THEORY OF OPERATION” subsection. If
you wish, you can follow along with the schematics.
The rnformatron IS presented in a very basrc manner
but more complete treatment of the subject can be
found in the technical sectrons of bookstores..
If you want to attempt to reparr your monitor, It would
be a good idea to read this whole section beginning
to end before starting. Pay attention to all warnings

To understand what goes on inslde the monitor,

Instead of laboriously analyzrng the branches and
small crrcuits that make up these groups. This WI/I

concrete,
knowledge of what makes up a monrtor

too low. the other circuits wrll be starved for power
and you may see a small, wavy picture, or none at all
Some ctrcuCs receive voltages that are h,gher tnan
what the power supply should put out. But they come
from the flyback
transformer whrch will be dlscussed
later
THE POWER SUPPLY ;
The AC going to the monitor from the game transformer is just like the voltage and current from your
wall outlet. It jumps up and down gorng positive and
negative sixty trmes a second. But a monitor needs
nice, smooth DC; direct current, not alteriating So
diodes c h o p u p t h e A C a n d a b i g electrolytic
capacttor filters it out to make rt even smoother.
Srnce
the monrtor is a big piece of electronic
equipment, wrth many crrcuits demanding a lot of
power from the power supply, there are also zener
&odes and transistors to help marn!arn a nrce,
constant, smooth voltageso that the mon~forcircuits
don’t jump around. And this IS what happens when
you see a wavy picture. There is AC creeprng
THE INTERFACE SECTION OF THE
CHASSIS The interface sectron of the chassis IS farrly easy to
identify. It IS rrght by the place where the video

sets of transrstors that receive the separate red,

There are two pulses going at different speeds

Vertical wave forms at 60 times per second
(or Hertz) and

trmes per second (Hz).

that you can’t see the electron beams for each color

cycle component of the sync as rt goes on its journey
to tie deflection yoke.
THE FLYBACK TRANSFORMER (OR
HIGH VOLTAGE UNIT) The picture tube needs high voltage to light up, ana
the power supply can’t meet this demand. The
flyback
transformer receives current alternating a!
about 15,750 trmes per second from the horrzontal
output transistor The “flyback” jacks up its rnpu:
voltage and puts otit a higher voltage alternating a!
the same speed. But. In your “flyback
there are
diodes that chop up the alternating voltage to make ii
a smooth DC output just IIke rn the power st.pply.
Ths IS what goes through that thrck red wrre to your
picture tube. THiS AREA HAS ABOUT 18,000
VOLTS ON IT AND IT CAN KILL YOU!!
The 60 cycle pulse goes to the verhcal
oscrllator to
make sure this crrcurt
goes back and forth (or
oscrllates) at 60 times a second. Without thus pulse

COLOR CIRCUITS
The color circuits are pretty straight forward The
srgnals go .nto the interface section where some
amplrflcatron and impedance matching occurs
These crrcults are pretty sparse and simpie Each
color lust Pas two transistors and a diode wrth some
reslstors and capactors From here the AC coior
signal is strt oy wires to the neck board.
Along the way to the output transistors, the 60 cycle
pulse IS shaped and amplified to do the job: the yoke

Wa:chrng a momtor lrke this, seerng only a horizontal

yoke or anything from the vertical output section on
back to the oscillator.
The color ou:put crrcurts

color srgnals
going to the transstors are controlleo
by two varrable
resistors called drive controls There
only two, one for the red and one for the green The

transistor is another varfable

THE PICTURE TUBE (OR CRT) The picture tube or CRT IS an output device. In other
words, the end result of the crrcurts work IS dlsplayed
by this part Actually, the output of other circuits is In
the neck of the prcture tube.
The beam lrmrter helps control the brrghtness level,
and the blankrng transistor rapldly turns the picture

there IS the heater. The heater bolls o f f
electrons from the cathodes so that they (the
electrons) shoot up to the screen to excite tne

monitor, these four to SIX retrace lknec can be seen
slanting dragonally across the prcture.
The cathodes are next. and agaln they emit electrons
to turn on the tube phosphors, makrng it glow. The
catnode can arc or short to the heater resulting In no
picture and a dafectrve

PROTECTION CIRCUIT To protect the hrgh voltage section against voltages
that are too hrgh comtng from the power supply
which could cause X-rays to he emrtted from the
“flyback”. a crrcurt senses the hrgher fpower supply
voltage, and using a transrstor, turns off the horizonta! oscrllator. Since the horizontal oscillator doesn’t
work, the horrzontal output transistor Pas nothing to
feed the “flyback” whrch in turn has nothrng to feed
the prcture tube. The momtor will be s lent, have no
picture, and will appear to be off But don’t befooled.
There IS stall that excessive amourt of voltage
coming from the power supply. To find out. check
the emitter on TR502 of the Wells Gardner monitors;
or the emrtter of X04 for the Electrohome monitor.
Here are the voltages you should receive.
Next con-e the grids. The first grid is grounded. The
follcwrng grid is the screen grad which receives about
BOOVDC
depending on the brightness settrng. The
next grid closest to the picture tube screen IS the
focus grad whrch gets about one fifth the amount of
voltage that is applied to the picture tube anode.
After jetting from the cathode through all thesegrids.
the electrons speed through a mask, a sheet of
material wrth trny holes, and then excite the trny dots
of phosphor in the inside surface of the picture tube
screen The green electron gun (or cathode and
crrcuitry)
spits out electrons which head for the
green phosphors only. Thesamegoes for the red and
blue guns The way the phosphor lrght blends
determines the color seen. Should these electron
beams become too intense, they may burn tne
phosphor. Wrth the monitor off, this can be seen as a
dark permanent image of the video informatlon on
the tube screen.
Wells Gardner = 127VDC
Electrohome = 120VDC
The best place to measure this vcltage on an
Electrohome monrtor IS at a pin marked Bl on the
chassrs Thus is because a 13 inch color Electrohome

tween Monitors
The easiest way to Identify the brand 0. momtoryou
are working with, assuming you can’t f nd the brand
name written on it anywhere, IS to see if there are two
crrcuit boards rfsrng up from the chassrs toward the
picture tube neck. In other words, the)’ stand up, or
are perpendicular to the chassis, with a black plastic
bracket holding them in place.This ~sadescr~ptronof
a Wells Gardner monitor. They use separate boards
for marn chunks of circuitry. Therefore you have a
“power board” (the power supply), 3n “interface
board” (the Interface sectron). and a “horrzontal/
vertrcal
board” [for the deflection crcuitry). Still.
there are a few parts on the chassis, but most can be
found on the board. An Electrohome monitor has no
separate boards, except for the neck board. and just
has a flat chassrs.
Another good way to determine whrch monitor you
have IS to check the transistor call out numbers that
are prlnted on the chassis next to the part For
Instance, on the neck board, one of the color output
transistors is TR401. If you look through the
schematrcs
or the parts lists, you WIII find TR401 in
the Wells Gardner Ilterature. On the other hand the
neck board transistor may say X101. Xl01 can be
found In the Electrohome hterature. So all Wells
Gardner transistor call outs begin wi?h TR, and
Elec:rohome transistor call outs start with an “X.‘.
