Restrictions
Stern Electronics is aware that
there are still some areas of the
country that maintain legislation
that restricts the use of amuse-
ment type pinball machines. We
would like to see your publication
attempt to locate areas where
restrictive ordinances are en-
forced, and subsequently we
would like to work in concert
with you and local operators to
eliminate these restrictions. We
feel that in light of recent court
decisions, particularly in Los
Angeles, Chicago and New York,
that outright bans as well as their
licensing restrictions can in fact
be amended to enable everyone
to enjoy the sport of pinball.
If you would publish in your
periodical some sort of request
for information on restrictive
legislation , we would pass this
along to other manufacturers and
hopefully all of us working
together might be able to accom-
plish the e limination of these
rest rictions.

Business articles

and accounting methods, sales
presentations to customers, com-
mission or pay plans to workers
and incentives, service charges,
etc. Basically, I would like to see

Prevalent problem
I would like to write about
some of the most prevalent
PLAY METER, A pril, 1979
problems in new pinball games
which are easy to solve. Williams'
solid state sound boar d gives an
audio hum . This is t he result of
wrong power grounding on t he
sound board. Cut the folio on bot h
sides (front and rear) of pins 5
and 6 on socket 10 J 1 and solder
a ground wire from pins 5-6
straight to the negative pole of
the large 10 mf capacitor (c29).
If the power switch is turned
off and on real fast on some
Gottlieb Joker Poker and Sinbad
games, it causes transient peaks
on the +5v line and gives away
free plays . To solve t his problem,
cut the two red wir es between
t he power supply and t he c:ru
board and add an iron core
inductor between t hem. I used
t he same type t hat is used on car
radios to prevent ignition dis-
turbance . The DC resistance of
the inductor must be as low as
possible to prevent voltage re-
duction. Measure t he volt age on
the CPU board after t he modifi-
cation and adjust it t o + 5v.
