The adjustable credit stop coil on
mechanical credit units cannot be
set for 1 credit. Since you are elim-
inating dime plays you can make
some wiring changes. For the sake
of simplicity and bill acceptor com-
patibility, you should make these
changes at the coin switch plug to
main harness.
Remove the male pins from positions
6, 7, and 8. Insert the pin with a pair
of slate wires into position 6. Insert
the pin with the blue wire into
position 7 and the remaining pin
with the slate-white wire into posi-
tion 8. Adjust the slug rejector to
reject dimes and nickels as shown
on the "Price of Play Procedure" in
manual.
Refer to "Price of Play Procedure"
and substitute quarter wherever it
says dime and half dollar wherever
it says quarter. This chart will show
you how to set price selector switches
and credit unit screws for your choice
of pricing.
If you have a bill acceptor, set the
number of pulses from the pulse
chopper. Remember that each pulse
now equals one credit.
Midway "Pac-Man" has been one of
the finest games produced lately.
As with any game, it has a few minor
defects. The worst one is that in
rough locations people will push
down on the joystick and bend the
points. My first cure was to replace
the blades with stiffer ones which
cured the problem for me. Midway
has come up with another cure that
will be used on later production
games. The nylon sleeve (0921-00701-
0000) that has the "E" clip on it has
been replaced with one that has a
shoulder on it. This will help protect
the "E" clip. A nylon washer (0017-
00104-0111) has been added be-
tween the "E" clip and the bracket
so that the joystick won't go down as
far. The wear plate (0932-00905-000)
should be inspected for wear once in
a while. (Note that this part has been
improved and has a new number.)
I recommend stocking this item. If it
is worn or damaged, the shouldered
sleeve will wear, causing problems
with point adjustments.
Note: Midway has incorporated this
change into their games being manufac-
tured now.
