Atari 5v Switching
Supply Low Voltage
Control Marketing Inc.
Intros New Pushbutton
By Al Vernon, Field Svc. Tech
Atari Ganes Corp
Milpitas, california
By
Power Supply: Sierracin 5V/15 amp
switching power supply.
Push buttons have been a problem from day
one. Contacts are always getting dirty.
Control Marketing Inc. of Illinois has a
new push button with internal contacts. It
works similar to a GM autorobile solenoid.
Also, it is much easier to use than other
button systems in tight locations.
Problem: Low or no +5 volts on the
logic PCB.
Solution: Check the capacitor located at
Cl9 on the switching power supply unit
(47mf/50V/105°C), replace if defective and
verify.
For more information call Atari Service at
(408)434-3950.

I first used the button with my Konarni 'lUP
GUNNER kit. I have had no service calls so
far. I was hesitant at first because this
system requires 2 contacts to make. '!he
switch is enclosed -so it remains cleaner.
If the contact plate wears out, it would
cost 25 cents to replace. It is rated at
5,000,000 cycles. One major manufacturer I
talked to (Atari) is presently testing it
beyond several million cycles with no
failures. Control Marketing: 312/593-6130.

Lock Ball Adjustment
By Terry Long, Shop Forerran
M & P Amusement Co.
York, Pennsylvania
Gane: Williams MIIJ,IONAIRE
Problem: Upper left lock ball gets
caught on wire form.
Solution: Move wire form closer to ball
kicker so that ball sits on it. Always
possible you will have to move micro
switch with it.
Performing this adjustment will reduce
service calls significantly.
