GOTTLIEB RESET MODIFICATION
CAME:
All System 80 Pinball
Reset Circuit Board-
Modification Kit#MA-158
A pinball game may "lock up" due to different out-
of-the-ordinary conditions. High static electricity
environments, a line voltage dip, or a defective coil
diode may cause the game program circuitry to lock
up into an inoperable mode. This lock-up may also
affect the game displays. One digit will burn brightly,
eventually burning out the display filament. Usually,
turning the game power off, then on, will re-initialize
the game for proper operation. However, if the
game is left in the inoperable mode for any period of
time, a burned out display will result.
SUBJECT:
Gottlieb now has availab_le a reset circuit modifi-
cation kit that, when installed, will automatically
reset the game if a lock-up condition occurs. The
reset board will detect the absence of the I RQ signal
and/or a display digit strobe. Either signal missing
will generate a reset pulse to the 6502 micro-
processor, resetting the game to the game over
mode.
The kit contains everything necessary for quick
on-location installation. When ordering, specify the
MA-158 Reset Circuit Modification Kit.
NOTE: The reset circuit modification is not nec-
essary if lock-up problems are not being experienced.
Contact your distributor for availability.
TAITO "CRAZY CLIMBER'' JOYSTICKS
BY TODD ERICKSON
The joysticks on "Crazy Climber'' get a good workout
due to the nature of the game. The original joysticks
have been wearing out on the upper stop. The
factory has a new shorter stick with smaller knobs to
eliminate some of the force on the shafts. This will
extend the life of these shafts greatly, but I still
recommend visually inspecting them while collect-
ing. One of the mounting holes for the micro switch
has an elongated hole for adjustment. I feel that the
screws used here should be lock-tited and/or lock
washered. A small piece of plastic channel around
the upper stop would give the shaft a longer life span.
