PROBLEM
PROBLEM
Bally pinball games with 6800 CPU board do not
provide "free play" option useable for home sales.
On 3 of these games, Super Hi-Impact: Sure is nice
of Williams to presort the wiring harness. What?
No sound?
SOLUTION
While some creative solutions include installing
externally accessible coin switches or setting the
replay score very low to award free games, these
have their limitations.
SOLUTION
Turn up the volume and the board resets? Seems
they got the test switch and the speaker crossed!

EPROM REPLACEMENT
~
A replacement Eprom, from Pintronics, for the U6
chip on those CPU boards provides the missing
"free play" option. This fast and easy game modifi-
cation frees up the replay option for things like
awarding extra ball.
The free play option is set using a DIP switch on the
CPU board, which means that the game will always
power up in free play mode, even after a battery
failure.
AVAILABILITY
The replacement chip is available for the following
U6 parts: E-720-40, E-720-52, E-720-53. This cov-
ers the games from Frontier through Cybernaut.
Chips for other games will be available depending
upon demand.
Also, the volume control plug was stuffed back-
wards! I think all 3 of these were made Friday
afternoon!

New Black Pinball Rubbers
A Field Test
Todd Erickson
Summit Amusement
St. Paul, Minnesota
SUBJECT
ALTERNATE SOURCE
When man first invented the auto he needed a
rubber tire. Natural rubber is a light tan with
lampblack added. The next logical question is why
are flipper rubbers red? They should be black!
I have been testing another set of black flipper
rubbers by Happ Controls on a Terminator II pin-
ball. With the high earnings of this game, I wore the
ends off the rubbers in the first two weeks. My new
black rubbers in about 6 weeks play and show no
wear.
NEW COMPOSITION
Data East is using them on their new game. An-
other first for them, and they are working with no
problem. (See follwing article for more info on Data
East's new /7,ipper rubber: ed).
CONCLUSION
I feel it is worth having these new fli pperrubbers on
all Terminator II pinballs. I will be upgrading my
entire route with the black flipper rubbers as I shop
the pinballs.
Data East/Wico Introduce
New Pinball Flipper Rubber
Data East and Wico Corp have recently developed
a new propietary flipper rubber. The new flipper
rubber, made from high quality virgin rubber with
a polysilicate additive, is very distinguishable from
other flipper rubbers since it is black. Black is
considered a more stable color since most dyes
combined with UV light cause rubber to break
down at an accelerated rate.
Recent test results showed that after 247 hours of
play, 16,288 balls played and 3,856 games played,
the flipper rubber had no cu ts or signs of wear. Also
the playfield around the flippers remained cleaner
as there was no rubber particle dust and dirt
created by deteriorating rubber.
In addition to the new flipper rubber, Data East
and Wico are also offering a shooter tip made from
the same durable rubber.
For more information on the new flipper rubber or
shooter tip, please call Data East Parts and Service
at 1-800-542-5377.
