"DONKEY KONG"/
ADDING A SLAM SWITCH
By Howard M. Smith
B&B Vending, Dallas, TX
H the front door of a "Donkey Kong" mini or
upright cabinet is kicked hard enough, a free
game will be awarded. Once this fact is dis-
covered, the door will be kicked to pieces in a
very short time. The only way to stop this
abuse is to add a slam switch that will reset the
game when the door is kicked.
A standard Midway-type slam switch can be
added to the front door quite easily as described
below:
1. The " Double-D" hole in the switch mount-
ing bracket must be drilled out to a round
hole so the assembly can be mounted with
the switch pointing down.
2. One side of the slam switch is connected to
ground, which is any brown wire on the coin
door.
3. The other side of the slam switch is con- ,
nected to about 4 feet of small gauge wire
which is routed through the harness back to
the CPU board.
4. On the two-board set, this wire is connected
to the bottom end ofRl 24, found at location
l/2P on the CPU board.
S. On the four-board set, the wire is connected
to the bottom end of R6 l, found at location
4F /G on the CPU board.
About 6 inches from the CPU board, we cut the
wire to the slam switch and installed a single-
pin Molex connector to simplify board removal.
