1) Due to a lack of availablllty of Hybrid IC
30-1000, Nintendo wishes to inform you
thatthelC3D-1001 canbeusedinplaceof
the 30-1000 with only minor modifications
to the power supply circuiting.
To replace a 3D-1000 in the PP7A +5v
circult(IC1), addapolyestercapacitor(.1 uf/
50v) across VR2 (2k pot). Also add an
electrolytic capacitor (1 0uf/16v) between
pin 10 (+ side) and pin 11 (- side) of the
30-1001.

n order to prevent the accumulation of
free credits by kicking the coin door, a
slam switch should be added.
In all cases, the switch ( a "normally open"
weighted reed switch) should be mounted on
the coin door. Connect one side of the slam
switch to the brown wire on the coin switch
(ground). The other side of the slam switch
should be connected to a wire which will be
run through the wiring harness to the CPU
board. At this point the installations vary for
the four (4) games.
