By Service Department
More than 8,000 operators, distributors
and manufacturers of coin-operated
anusement, music and vending equiµnent
attended the annual Industry exposition
this year.
There were 185 exhibiting companies
occupying 486 booths and 60,000 square
feet of floor space on two levels.
r-t>st attendees felt it was a quality show
top to bottom, although many said it was a
show without any one spectacular game.
The ~ Expo '88 will be held Noverrber
3-5, at the Hyatt Regency Chicago.

FACT'S:
AMOA is a non-profit association comprised
of approximately 1,300 operators,
distributors and manufacturers.
There were an estimated 5,500 operators of
coin-op amusement and music equiµnent in
the US in 1986.
In 1986, there were an estimated 1.5
million coin-op games on location.
In 1986, coin-op games were located at an
estimated 300,000 street locations
(taverns, .r estaurants, etc.) .

All new Konami PCB's utilize a 56 pin edge
connector. This connector complies with
the standard set by JAMMA (Japanese
Amusement Machine Manufacturers
Association).
However, all Konami PCB's manufactured
prior to WP GUNNER utilize a 36 pin edge
connector. These games include:
SUPER COBRA, SQW.IBLE, PCX)YAN, I.OCCMJI'ION,
CIRCUS CHARLIE, L'IL HUSTLER, JUID FIRST,
TIME PIIDT, GYRUSS, 'lUI'ANKHAM, 'IURTLFS,
SUPER BASKETBML, MOCJ\ ZONE, PANIX>RA I S
PALACE, TIME PIIDT '84, TRACK 'N' FIELD,
HYPERSPORI'S, ROAD FIGHI'ER, YIE-AR KUN} FU,
KICKER, RUSH 'N' A'ITACK, MIKIE, FR AMIDAR, ROC 'N ROPE, THE END, JAIL BRFAK,
NEMESIS, STRATOOY X and 'IURTLFS.
Because of the large amount of video game
cabinets that are wired for Konami's old
standard edge connector, Konami now offers
36 to 56 pin adaptor PCB's. This adaptor
PCB enables you to simply plug in a new 56
pin JAMMA PCB (not only Konami's) rather
than rewiring.
Contact your authorized Konami Distributor
for further details.

Electrohome G07
5 Year Capacitor Clean-up
By
Sam Cross
Godwin Distributing Co.
North Little Rock, Arkansas
Electrohome G07's - Round 'em up!
Well pardner, I believe it's time to
corral all the Electrohome G07 rronitors
for their annual five year capacitor
change!
These rronitors are dropping like flies
now. If you want your rronitor to be
looking as good-as-new and trouble-free on
the route, you need to order a parcel full
of each of the capacitors listed below and
install them all at once when you have the
chassis out on the bench.
C511
47 microfarads at 160 vdc with radial
leads. When this cap bakes open you're on
A the down-and-out until you replace it.
W eauses the high voltage to come up then
shut down. CSll serves a critical function
of regulating the 125VOC B+ voltage.
C517
100 microfarads at 16vdc with radial
leads. This cap, along with C518, provides
the proper arrount of signal throughput in
the pincushion section. When these dry
out, the whole picture becomes real
hunkerjawed - you know, not rectangular.
C518
220 microfarads at 16vdc with radial
leads. See C517 description above. Don't
want to be repeatin' rr~self.
e

[15)
C523
1 microfarad at 160vdc with radial leads.
Concerned with the width section.
Cl07
10 microfarads at 250vdc with radial
leads. This one's perched up on the neck
board and causes uneven intensity problems
when it goes bad, which is quite often.
Before you apply power to your recapped
chassis, check the correct polarity of the
caps or you might have a real blast
powering it up!
Happy Trails to You.

50V Flipper Coil Problems 11
By
Erwin H. Boot
Automatic Music Co.
Tasrrania, Australia
Further to Rayrrond Ross's note regarding
Williams S0V flipper coil problems in the
July '87 STAR-lrTECH JOURNAL, here's an
addition:
SYMPIDM:
Fuses blowing for no regular reason; game
occasionally jumps to diagnostic rrode
during play; while in test rrode, operating
a flipper will cause program to jU111p to
next test.
PROBLEM:
mentioned in July by Rayrrond Ross, a
broken diode on a coil can cause really
weird problems. An intermittent or broken
diode across a flipper coil will cause all
of the above and maybe more.
As
C408
4.7 microfarads at SOvdc with radial
leads. Associated with the vertical
section. Not essential, but when the
chassis is out, why not replace it.
Probably bakes open due to the heat from
the vertical section.
Footnote: Diodes across coils and drop
target switches are subject to a lot of
vibration and should be regularly checked
for broken leads - i.e. breaks either frorr
their solder termination or from the
inside of the diode itself.
c412
.
3.3 microfarads at 160vdc with radial
leads. Provides some filtering in the
vertical section.
This involves pulling the leads with
tweezers or long nose pliers. It is a
particular problem for drop targets on
PHAROAH, BIACK KNIGHI', SPACE SHUT.I'LE and
mIB'I'.
