INTERCHANGEABILITY
NOTE: The board revision is on
the trace side on the bottom near the edge
connectors inside a box. On the com-
ponent side it is on the bottom, furthest
from the connectors. [Q]
This circuit is very similar to the
type used on "Missile Command" and is
very reliable.

Williams "Hyperball" Service Notes
The ball shooter circuit on Williams'
"Hyperball" has a fuse change. On earlier
games a 15-amp fuse was used. This was
changed to a 4-amp slow blow fuse. On
the sticker inside the light box it still
indicates a 15-amp replacement. This
should be changed to eliminate confusion.
The auger motor jams with the
slightest amount oflint from the playfield.
If your auger motor has a metal fan
instead of a plastic one, then you need the
kit from Williams - Part No. K-509-2.
Williams Video Board
Interchangeability
Contrary to popular belief, "Defender"
and "Stargate" CPU/Video Boards are
not interchangeable. However, "Stargate"
and "Robotron" CPU/Video Boards are
the same and can be switched with no
problems.
Atari's "Centipede" Board Revisions
Some problems may occur with the track
ball even after new -02 steering boards
have been installed and resistors R83-86
and RI 30-13 3 have been changed to
6.8k. This can be checked in test mode by
spinning the ball hard to the left. The
moving image will move backwards and
then "lock up" with eight images flickering
even after the ball has stopped moving.
This problem is caused by revision "A-
F" which has no capacitors in the input to
LC. LS157. "G" revision boards have
capacitors and resistors arranged so that
the object displayed in any mode will be in
the direction in which the ball is traveling.
This requires a lot of work and should be
done only on a game in the shop in case
any problems arise with cutting traces,
etc.

NEW INPUT
PROTECTION
CIRCUIT FOR
WELLS-GARDNER
COLORX-Y
DISPIAY
This display contains an additional small
printed-circuit board (PCB). The PCB is
mounted in "piggy-back" style on top of
the Deflection PCB.
The input protection board was
added to protect the fuses in the display
from damaging input voltage conditions.
Without this board, the display fuses
might blow in the event of an intermittent
or long-term game PCB failure. With this
board, the screen will momentarily go
blank if the average X- or Y-axis voltage( s)
exceed a certain level. The screen then
automatically recovers for normal game
play and earning when the voltage( s)
return to normal.
If this display is used in Atari
"Tempest" games, be sure to correctly
adjust the X and Y SIZE and CTR video
pots on the "Tempest" Analog Vector-
Generator (main) PCB. The instructions
for these adjustments are printed on the
"Tempest" schematics - Sheet 2, Side B
- 3rd printing or later. Improper adjust-
ment may cause the screen to go blank
during normal game play.

STERN
"TURTLES"
UPDATE KIT
Stem has released an update kit for their
video game, "Turtles". The kit is a 9-chip
program change enhancing the game play.
The new program makes it easier for the
player to score, adds color, and improves
overall game appeal. Also the video images
are changed. The beetles are now race
cars which adds considerably to the
excitement of the game.
The "Turtle" update kits are avail-
able, at no charge, from your Stem
distributor (with return of original roms).
Order Kit #RBI.

SOLUTION
Newport Joysticks mod. 125
(black color)
Subject:
Intermittent contact on leafswitches on
early 1982 shipments. Small particles of
the white Delrin(plastic) contactor, which
moves the contacts, is being rubbed off by
the edge of the leaf contact. This plastic
dust settles between the contacts.
Solution:
Call or write: Newport Machine Design,
P.O. Box 418, Bishop, CA 93514, 714-
873-4431. They will send you a whole
new shaft assembly from the New Joystick
mod. 125A (golden color) with a perma-
nently attached large knob, heavier rear
bushing, larger spring and shallower
contactor. This will solve the problem.

AOE '82 SHOW REPORT* WILLIAMS "HYPERBALL" LOCATION NOTES
WILLIAMS "HYPERBALL" HANDLES* RESPONSE TO ROWE LETTER
By Todd Erickson, Summit Amusement, St. Paul, MN
AOE '82 Show Report
Attending the Amusement Operators Expo
for the first time this year, I received a pleasant
surprise. I expected a small show with a few
people. What I found was a large show packed
with participants. Thursday was an early bird
session - the manufacturers faced the firing
·Jine. The main concern at this session was the
manufacturers supplying a conversion kit for a
poor game. (Most of the people there had been
in the industry for only a short time.) If we
could buy kits for all of our games, this would
be a successful business for only a short time.
The locations would find this out and we
wouldn't be operators anymore. The manu-
facturers would no longer have the necessary
money for research and development and the
quality of the games would drop. There are
only a few games that earn big money.
The next three days were filled with
activity. There were two sessions of seminars
each day. I attended a few of them. The
comment I heard from many people was that
they considered the sessions very good to
excellent. The seminars that received the best
comments were put on by Randy Fromm,
Robert Stone, and Frank Seninsky. Comments
on these seminars varied, depending upon the
experience of the individual participants. Many
people felt the way this show is growing, it
could rival the AMOA for the top show.
Sending key employees to the AMOA is about
the same as sending them to the local distri-
butor's showroom. Sending them to the AOE
gives them an opportunity to learn some valuable
skills for the business. The AOE faculty gives
their years of experience and opinions on ways
to improve where they went wrong. These facts
could save you thousands of dollars.
The hit of the show had to be "Robotron"
by Williams. This is a high technology action
game, robot vs. man. "Zaxxon" by Segal
Gremlin is a new flying game with unbelievable
graphics. Cinematronics appears to have a
giant hit on their hands with "Jack the Giantkiller''.
This is the first color raster-scan game by these
people. Exidy showed their product, "Victory".
This is a much refined version of what they
showed at the AMOA. Their hardware package
is one of the best in the industry. The book-
keeping is excellent. This has to be their best
game to date. Gottlieb was one of the surprises
of the show. Their "Reactor" is a new concept
game. I feel that this is going to be an excellent
players' game. This game will be the first step
for Gottlieb to establish itself as a top video
company. Midway's main game was "Ms.
Pac-Man". With the success of this game, they
will probably be making it for the next six
months or longer. Stem's new game, "Frenzy",
looks very good. It is a high technology
"Berzerk".
Williams "Hyperball" Location Notes
Williams spent a tremendous amount of time
engineering this game. So far, my games have
worked better than most pin games I have
purchased in the last few years. With any new
game, the operator must learn all about it.
"Hyperball" is a dark game and must be in
some light. The game should not be elevated in
the back. Most important is that the players
must be helped to learn the game. Either have
the instructions up by the game or have the
location know about the game.
The only parts I feel should be stocked are:
I. Damper washer for plunger 03-7725
2. Spring shooter 10-370
3. Stop plate A-9215
4. Coil SD-245-1588 and sleeve
5. Optical interruptor assembly B-9093
6. Trigger micro 5647-09633
With the action of the game, the only
part that showed any wear is the shrink tubing
going into the cannon. The 110 volts for the
cannon has to be protected. Only a few games
have the shrink tubing. Later games have
nylon. If you have shrink tubing, order the
nylon part from Williams. The handles on the
game must move freely from right to left. If it
binds in the center of the movement, the drive
arm that makes contact with the cannon was
probably inadvertantly bent. One last caution
is to cover the playfield when moving the game.
Because the playfield is black, the sun may
cause the playfield to warp. When the game is
on location, keep it out of the sun.
Williams "Hyperball" Handles
Handles on "Hyperball" have two small holes
drilled into them for roll pins. The center one is
for the trigger, the other one holds the handle to
the drive shaft. On a few early models of
"Hyperball", the roll pin holding the drive
shaft may be too short.
If the pin makes contact on one side
only, it will eventually break. When this happens
the trigger will then break also. I recommend
checking this roll pin, and verify it is a 3/ 32" x
I". This will eliminate trigger breaking problems
and the resultant Joss of control complaints.
Response to Rowe Letter
(S•TJ, April 1982)
The articles I write are about items that are
causing problems in the industry. Many times
this may be a small problem (i.e. an interlock
switch in a high production game) rather than a
major problem with a particular game of which
only a few hundred were made. The reason I
continue to write about Rowe changers is
because I feel they are the standard of the
industry. In my area, over 95% of all bill
changers are Rowe. I have the majority of my
route on Rowe $1/$5 changers.
Any time an operator is in jeopardy of
losing a large amount of money because of a
simple problem, I feel something must be done.
I contacted my local distributor with the problem
of changers being tipped over. They, in tum,
contacted Rowe, who felt this was a minor
problem. When I spoke to a Rowe representa-
tive myself, he didn't care to obtain the name of
the operator this happened to so they could
possibly look into the matter further and/or
determine the extent of his loss.
I agree with Rowe that all changers
should be bolted down. But there are locations
that are old and the buildings are made of
wood. If there is no way of getting behind the
wall or floor, large screws or lag bolts could be
used to hold the changer down. If, however, the
customers know that they can tip the changer
over and get the money out easily, it is more
likely to occur. It doesn't take much to rip a
screwed-in changer out of a plaster wall or
wooden floor. I don't know of any person who
is able to tip a big food vendor over. For that
matter, all ofmy games have covers on the cash
box. This would keep the money in the box if
the game was tipped over.
I am certain Rowe is always willing to
listen to suggestions for improvements. This is
reflected in the annual Star..-Tech Journal
Reader Survey. Whatl published was a problem
and then a cure for it. I would not write
something like this for any publication that the
general public might see.
Furthermore, the only protection Rowe
presently has to keep scraps of paper out of
their changer is a kit they supply from the
drawings I made for them.
