OPERATOR'S CONCERN
Do you have a problem removing
glue residue and paper labels
from plexiglass or glass.
Plastic ramps are expensive.
Plus, on older games they are
hard to come by.
You have just purchased a second
hand Atari Race Drivin' and
would like to keep one or two
parts in stock that might be
needed in the future.
SOLUTION
SOLUTION
Try straight ammonia. It's cheap
and works great!
Williams now manufactures
Ramp Side Protectors. They are
on all of their new games.

On Floppy
SUBJECT
Phillips (call 1-800-526-9354)
has an IBM-pc & compatibles
floppy that can access the full
ECG replacement semiconductor
data base of over 262,000 indus-
try part numbers.
Typical access time of under 1
second! Over 4000 ECG compo-
nents are available in the pro-
gram, making it the largest cross-
ref data base available.
If your computer has 640k of
RAM, a hard drive, and a floppy
~either 3.5" or 5.25", you can order
one of these and perhaps improve
one of the most tedious problems
techs have, hunting up parts.
Call Phillips.
You want know the repair record
and failure chart on this piece
and what parts to keep in stock.
Many of these side protectors can
be fitted onto older games. Then
you have a permenent repair.
BOTl'OM LINE
These will become a big money
saver for the operator. Congratu-
lations, Williams -an excellent
idea!

PAST EXPERIENCE
The Race Drivin' and Hard
Drivin' games are pretty solid.
• The biggest single failure I have
seen is the solder joints on the
pedal board's voltage regulator
cracking. This is a basic TO220
package 7812 regulator.
• I also have fixed a few shifter
assemblies but they have had
various minor problems.
Overall a good dependable game,
no need to be overly worried with
this used piece.

Williams New
Electronic Flipper
& GoldEOS

SUBJECT
It has now become well known
that Williams/Bally Midway has
their own electronic flipper. The
electronics are used to eliminate
the tungsten EOS (end-of-stroke)
switch and cabinet switches.
These tungsten swit.ches are re-
placed with gold contacts. The
EOS is now normally open and is
used to give an exact feel to that of
conventional mechanical/electric
flippers.

ings from the plunger also slows
down the flipper action.

most wire and diode breakage.

If you don't have parallel coils in
your pin game, upgrade them on
all 50 volt games. Be sure to use
coils with similar power. And re-
member that adjusting the EOS

CLEANING PREcAUTION
One major caution that should be
mentioned here is to use only non
abrasive cleaner like paper, or
business card to clean these con-
tacts when it becomes necessary.
They are gold flashed and can't be
filed without ruining them. Also,
they are software controlled, so
for that reason you can't install
them into your older games.
RETOFIT SPRING
Another major improvement to
this flipper assembly that can be
used in older games, is an exter-
nal spring which eliminates the
conical spring used until now.
The problem with the conical
spring is that it can damage the
plunger.
When the plunger is damaged, it
ruins the sleeve and this allows
the plunger to then rub on the
sure to also replace the sleeve and
coil stop all at one time. Part# for
EOS is 01-9375 or you may be
able to use an "L" bracket.
I feel that all your older games
should be upgraded when they're
next shopped. Older games
should also have the terminal
end of the coil facing the front ( 01-
opening also cuts power when it
opens sooner.
CONCLUSION
Congratulations to Williams on
an excellent job with their new
electronic flippers.
