announced he'd be over at the
airport speaking at 6:40, so we
didn't give it a second thought
that he might get in the way of a
$45 boatride... he didn't, as
Opryland's gracious Jimmy
Tresler assured us that the boat
would not leave without us-or
any of the other 450 people at the
hotel who needed to shuttlebus
past Bush over to the dock ... it left
on time ... we met a couple of self-
proclaimed
Wisconsin Cheesehead Party
Babes, Marge Corey and Tammy
Reflke, who were vacationing for
the week... they report having
back-home fun at the Oneida Ca-
sino in Green Bay Wisconsin ... we
drank and laughed about their
encounter with the Secret Ser-
vicemen at the Ramada the night
efore-they thought the sun-
glasses security men were about
to burglarize their room ... off the
boat and into a cab for a cross-
town ride to Rodeos, where a dj
spins country dance music non-
stop for the beer-drink.in' two-
step rockin' crowd ... coin-op
games absent but for a pool table
that got plenty of action ...
Thursday-Saturday, it's up early
for the AMOA Show, 10AM-5PM
and then suite-hopping with our
good friend Tosh Morita of
Fillmore, Inc., Osaka (fax him at
011-81-6-845-2510 for his stock
list) at the Strada suite, where
America's next street fighter
blockbuster title TIME KILL-
ERS was getting its sound up-
date over the computer modem
from the hackers back at the
home office ... what a knockout of
a piece, taking both SF2CE and
Mortal Kombat to then-th degree
of gore with the power to behead
your opponent, and boasting of
twice as many maneuvers ... we
went back nightly to see this
piece that was not on the show
floor and picked it for best of
show ...

(easy to play golf video kit, 2p/4p);
Taito's MONKEY MOLE PANIC
(real cute linked video/
wackamole for redemption).
Grand Old Opry is a tradition on
WSM 650AM, heard all over the
east, but Buffalo's on the wrong
side of the Appalachian Moun-
tains so we decided to go see it
and got tickets Tuesday for the
9:30PM Saturday late show

PROPERLY POWERING
y OUR COIN-OP EQUIPMENT
I was inclined to write this article
because of the amount of prob-
lems I have solved over the phone
by telling the operator or
routeman to check the AC voltage
going into his machine. It seems
that there has been a rash of this
going around lately, almost like
the measles.
PROPER GROUNDING
Grounding is probably the last
thing anyone is concerned with. I
cannot stress how important this
is, however. It should never be
defeated.
I would say that more than fifty
percent of the equipment that
comes in for repair has no third
wire ground. It has either been
cut off at the plug or left discon-
nected on the inside of the ma-
chine.
There are many reasons to have
good grounding but I will only
cover the important reasons
here. The most important reason
is to keep any spurious AC from
entering metal parts of the ma-
chine. This could become danger-
ous especially if there are other
machines with it.
With a bad
ground orno
ground there are
much higher risks
of component
failure due to
noise and static
discharge.
If one machine is grounded and
the other has some AC on i t ~
chassis the result is an electric
shock for whoever touches them
both at the same time. This can
prove dangerous to folks who are
old or to players in a damp/wet
environment. You definitely
don't want to kill anyone or be
sued for negligence.
Another important reason for
good grounding is safety of your
electronic equipment such as
CPU boards and other Pcb's.
With a bad ground or no ground
there are much higher risks of
component failure due to noise or
static discharge.
I am not going to go into the
theory of this as there are several
good books written on the subject
of grounding. If you must use a
twoprongplug, useanadapterto~
give you a third wire ground to
your equipment. The better ones
have a pigtail wire coming out of
them.
