After the data in all the bookkeeping registers has been recorded they can be set to zero by enter
ing the key code 99B. Note: The coin-in count (OA) is not affected by the reset code.
The game retains in its memory the number of coins dropped through the coin chute, total
number of coins and credits (replays) and the actual number of games played. In addition, occurrences
of certain features specific to the game model will be recorded to aid in monitoring overall revenue
performance. This data is stored in U45 and U49 on the MPU module (non-volatile CMOS RAMS).
A storage battery, connected to U45 and U49 only, provides power whenever the game
is
turned off
(see schematic W-1222, sheet 1, left side). The battery is charged through C R29 while
the
game is on.
Since the standby (quiescent) power consumption of U45 and
U49
is in microwatts, a
fully
charged
battery can maintain storage of bookkeeping and score information for months. If memory retention
is affected, check for battery failure and/or a leaky charging diode.
