Checklist
If your Stern "Berzerk" video g~me
gives free credits when the power is
deliberately intenupted {tampering
with the line cord) Stern's customer
service group recommends these mod-
ifications and inspections.
1. Remove the AC power lines for the
service outlet from the cable harness
located on the right side (front view)
of the cabinet. Isolate the AC lines
and retie the harness.
2. On coin chute #1 (closest to the
coin door hinge} remove the blue/-
white wire and replace it with the
brown/white wire that is taped and
hanging from the coin door harness.
This is the unused #3 chute. {After
this modification, check program-
ming for correct coins/ credits set-
up at this chute.)
3. Check for correct polarity of the
Ni-Cad battery on the logic boards.
4. Check for correct bookkeeping RAM
at location IE (#6513 or #6514).
5. Visually inspect the RAM and its
socket at location lE for looseness
or bent pins.
6. Check for correct polarity at the
incoming line filter {AC power
lines}.
Performing these modifications and
inspections should eliminate the free
credit problem. If you have any ques-
tions about these procedures, call
Stern's customer service engineers at
800-621-6424.

S'\).q~ GAME
IMPROVEMENTS
by Todd Erickson
All of us have to agree that the games are much
better in respect to income and maintenance than a
few years back. We also have to understand that the
manufacturers make many different models a year
so there will always be a few problems.
·1n the operator's eyes every game will have some-
thing that can be improved upon. Many of his points
.:r;nay be good, but he never seems to take the time to
fill out the card that comes with the game and send in
the information. This information is needed by the
manufacturer so that they know what the problems
are with their products. If just a few people notify the
manufacturer, then nothing may be done.
Even an easy service call can cost over $25.00. There
must be a better relationship between the operator,
distributor and the manufacturer in the 1980' s.
Here are a few of my major complaints;
1. Coin rejectors can be jammed with Canadian
coins.
2. Back door interlock switches are mounted high
without a spring on videos. If the door warps or the
lock is loose, the games go off.
3. Poor quality in critical points (points that if they
fail the_ game is out of order) on pin games. I can
remember when Gottlieb had 2 points on score
reels.
4. Power supplies and fuse blocks on the bottom of a
video game so that coins and hardware can fall on
them and short out the game.
5. Games that are not drink proof. Who pays for
repairs on a 2 year old game?
6. One fire button on a video game.
The list could go on for some time, but I think the
point has been made. We must all become a little
more involved in our industry.
