-.., PINBALL GAME RELAYS
Relays mounted on small PC boards with the
applicable 'snubber' circuitry parts are
now available. These are being included in
current garnes (OOAD Kil:l'GS, PIN*Bar);
however, they are also applicable to older
garnes (HIGH SPEED, GRAND LIZARD), when
replacements for the older relay and
separate components snubber circuits are
necessary.
Conversion Hints
By
prevent burned edge connectors on down
the line, on any game that you convert,
cut and tie all of the ground wires
together about three inches from the
connector, and do the same with the 5 volt
lines.
To
The part m.mbers for these Relay-Snubber
units are p/n C-11232 for those used in
the Solenoid/Flasher circuitry (with an RC
{resistor-capacitor) network in the relay
circuit), and p/n C-11232-1 for those used
in the General Illumination circuit
(without the RC parts).
This allows several connections instead of
just one or two, to carry the heavy
current demand of the board.
Also, when you set the 5 volts to the
correct level, don't measure it at the
power supply!
Measure it at the chip furthest away from
the edge connector on the logic board, for
it only matters on the logic board, not at
the power supply terminals.
HIGH EARNI1'(;S HINI'S!
Clean your playfield, polish the glass,
and do those preventive maintenance
touches that keep your garnes in top shape
for your players (and for your earnings).
,,.-.., System 11 (used on HIGH SPEED, GRAND
· LIZARD, PIN*Bar) has a great deal of
"audit" (bookkeeping) information
available, by which you can evaluate how
game features are affecting your earnings.
When you do the usual garne servicing, take
time to observe the percentages provided,
so that you can set your garne adjustments
to give the player a good game, and at the
same time, obtain a top rate of return.
Check the garne's manual to see the choices
on the rnany adjustments provided by
Williams. These adjustments are easily
made; you can 'fine tune' each game to fit
the players' skill at each location.
Good Adjustments= Good Games= High
Earnings!
