Due to its solid-state electronic circuitry, this Atari unit should require very little maintenance and only occasional adjustment. Information given in this chapter and elsewhere in this manual is intended to cover most servicing situations that may be encountered at the game site. The procedures given are in sufficient detail to be understood by a person with moderate technical background.
If reading through this manual does not lead to solving a specific maintenance problem, you can reach Atari's Customer Service Department by telephone Monday through Friday, from 7:30 a.m. to 4 p.m. Pacific Time. From California, Alaska and Hawaii, call (408) 984-1900,' from the remaining 47 states call (800) S3&-6892 (toil-free).
If you are interested in gaining more information on video game technology, especially the electronics, we recommend reading the Video Came Operator's Handbook, manual number TM-043. This book is available from Atari, Inc., Attn. Customer Service Department, 2175 Martin Avenue, Santa Clara, CA 950S0 for $5 each, or from your distributor.
The exteriors of game cabinets and plex panels may be cleaned with any non-abrasive household cleaner. If desired, special coin machine cleaners that Teave no residue can be obtained from your distributor. Do not dry-wipe the plex panels because any dust can scratch the surface and result in fogging the plastic.
B. COIiV MECHAJSISM
Figure 3-1 shows the back side of the coin door assembly where the game's two coin mechanisms are mounted. Inciuded is the lock-out coil assernbiy; the lock-out wires are connected to this assernbiy but are hidden behind the coin mechanisms. During the attract mode the microcomputer energizes the lockout coil, causing the lock-out wires to retract far enough to aflow genuine coins to reach the coin box. But during the ready-to-piay mode when the LED is lit, and during the play mode (and also when AC power to the game has been turned off),the lock-out coil is de-energized, causing the lock-out wires to move out far enough to divert coins over to the return chute.
Directly below each coin mechanism is a secondary coin chute and a coin switch with a trip wire extending out to the front edge of the chute. When the trip wire is positioned correctly, a coin passing down the secondary chute and into the coin box will momentarily push the trip wire down and cause the switch contacts to close.
Also shown in the photograph is a slam switch assembly, it has been included to discourage any players who might try to obtain free game plays by violently pounding on the coin door to momentarily close the contacts on a coin switch. The slam switch contacts connect to the microcomputer system, which will ignore coin switch signals whenever the slam switch contacts are closed.
To remove jammed coins, and for maintenance cleaning, each magnet gate assembly can be hinged open without removing it from the door, as shown in Figure 3-2. Or, if necessary, each coin mechanism can be entirely removed from the door merely by pushing down on a release lever and simultaneously tilting the mechanism back, then lifting it up and out. This is shown in Figure 3-3.
