Stern has introduced a new type of joy stick board, called a photo reflective unit. It
operates by the use of infra-red light that is transmitted from, and reflected back into
the lens by a polished washer. There are 4 photo reflectors (up, down, left, and right).
When trouble-shooting a reflector, there should be +5V between Pin 1, which is
designated by a white dot, and ground, (pin 1 on connector J-1 ). By covering the
reflector, the voltage should drop to 1 ½ to 2 volts if the reflector is good.
After determining that the photo reflector is good check the outputs of the LM339
(location U-1 on the PRU-1000 Bd.). Still using pin #1 for ground, check the following
pins on connector J-1 for individual outputs. Pin 7 for left, pin 4 for right, pin 3 for down
and pin 6 for up. Again +5 Volts should be measured. By covering the reflector for the
direction that is not working, the voltage should go to 0 volts. If it stays at +5 volts, the
LM339 is bad. If the volts drop to 0 and the player still won't move, check the
connector and the cable for bad connections.

ATARI STEERING TEST MODULE
Atari , for many years, has been making a steering circuit board that is used
on every steering wheel or trak ball in all games. From time to time like
everything else, they fail. Sometime, it is a royal pain to determine which
is bad-the steering P.C.B., the main logic or wiring harness. With all the
vibration and dirt this little board goes through, it's amazing the problems
aren't severe!
That' s why it is important for every operator to have one of these test
modules. The module plugs onto any Atari steering P.C.B. and by rotating
the steering wheel or trak ball a set of l..E.D.'s will illuminate sequentially
(cascade) in the direction of rotation or reverse by rotating in reverse.
Atari Steering Test Module-$50.

color monitors to install in older cabinets but discover they have power supply
requirements that cannot be met. This power supply is the operator's
answer. It develops the following voltages:
• 5 volts DC 3 amps (5 amp optional)
• 12 volts DC I amp
• -5 volts DC I amp
• 16 volts DC unregulated for audio circuits
• 110 volt AC isolation for color monitors
•Price 1-4-$100. 5-10-$90.
