Check your Mad Dog games:
Make sure your laser disk player
in your Mad Dog game is venti-
lated. Miµe was completely en-
closed with no air ventilation at
all.
SYMPTOM
The first thing that you see is a
gummy substance on the edge of
the disk or on the disk drawer.
This will get inside the player and

see when you first tum on the

Mine is properly grounded and
the game still burns up the CIA
chips on the Amiga 500 board all

any parts from them.

PROCEDURE
Every pinball/video game that
comes through my shop gets the
battery, usually a 3.6v nicad

BOTTOM LINE
A cheap, easy bit of preventive
maintenance that possibly saves
a big headache later.
SOLUTION
Drill holes and install a fan to the
to vent the hot air outside before
your player goes bad.
AL.so CHECK
Make absolutely sure your gun is
grounded all the way from the
