SERVICE TIP:
Tailgunner 2
The two nine pin plugs to the audio
P.C. board look the same. One plug
has + 5 , + 25 , -25 volts , while the
other has 5 volts only .
You should mark these plugs
before removing them from the P . C.
board so they can be easily differ-
entiated . This will avoid the extensive
damage that would result from
getting these interchanged .

CORRECTION
An ite m in the Technical Topics
section of PLAY METER , June 15,
1980 included an incorrect part
number for GE varistor MOV-11. The
article concerned retrofitting some of
th e older model RMC phonographs
("Varistor installation how-to ," page
76) . The correct General Electric part
number is V56ZA8 . The correct part
number does occur on the RMC
drawing, kit 11 52551. PLAY METER
apologizes for any confusion caused
by the June typographical error .
C ·Common
Si ngle Coin Slot
Some video game manufacturers use a single coin sense input to the logic
system from a double coin slot door .
Figure 1 shows the different coin switch configurations. As you can
see, in the double switch arrangement , the switches are not wired
identically .
This can be confusing when troubleshooting games utilizing this set-up
[Exidy Star Fire , Vectorbeam Warriors , C inematronics Tail Gunner] .
Figure 2 illustrates a typical single sense input to the game electronics.

OMAA urges care 1n buying
Ohio operators are being urged by
the state association to use caution
when
purchasing
vending
and
amusement machines from certain
out -of-state sellers .
James H . Hayes, president o f the
Ohio Music and Amusement A sso-
ciation, said the OMAA has received
reports from the northwest area of
the state , of a "fast talking team from
Michigan" who promote "non name
equipment with low income-drawing
ability ."
Hayes recommended these steps
be taken by machine permit holders
before signing a contract to buy
equipment :
1. - Contact the local Better Busi-
ness Bureau for a report on the
people who are selling to you .
2 . - Carefully read the terms of
the contract, especially the clauses
having to do with time payments.
interest rates, and assignments .
3 . - Get a written guarantee for
service and parts .
4 . - Consult your present equip-
ment operator when planning to buy
your own vending and amusement
equipment.
Hayes suggested that the permit
holder consider three basic items
when approached by out-of-state
sales crews: service. integrity, and
dependability .
" Permit holders should stop to
consider that the jukebox repairman
is a professional who is always
available at no cost," said Hayes.
"He's trained to work on the latest
computerized equipment and will
answer calls at any hour , including
weekends."
Few other professional repairmen
can be found for breakdowns at
crucial times, such as busy traffic
nights , he pointed out.
Ohio's music and games operators
in the OMAA "subscribe to a
stringent code of regulations ," Hayes
said . That code includes attention to
the role of the coin -op industry in the
life of the community , recognition of
"the highest possible standards in
order to properly serve the public,"
and fair and honest dealings with
customers and the general public at
all times. Members are committed "to
compete fairly and ethically, thereby
making our industry more efficient by
stimulating the greatest possible
service to the public," and to faith-
fully execute all contracts and to
conduct business in such a manner as
to generate the confidence and
respect of customers, the industry as
a whole . and the general public.
Hayes said any questions about
OMAA can be answered at the head-
quarters office , 41 S . High Street,
Columbus 43215 , or by the Better
Business Bureau .
