REPLACEMENT TIP
This game uses a rotary joystick. If you have
one that gets broken and you have any Atari
Tempest rotary joysticks laying around ... go
ahead and use 'em-these will work great for
replacements.
PROBLEM
The 2 player and 5 player score displays
where continually strobing.
REPAIR TIP
Also if you have any rotaries that are just bad
and in need of repair, you can use the Atari
sensors that were used in their trackballs
( Centipede) for replacement.
NOTE
Although the Romstar sensors are different
(physically) the holes are on the board and
the traces are on the board to use the Atari
type sensors also.

SOLUTION
Finally found out that the circuit was miss-
ing two 3 Megohm resistors which are physi-
cally mounted right above the Master Dis-
play. Question is: Why did Williams put two
diodes in there from the factory instead of
the resistors? And what component should
really be in there on this model? I called
Williams. They first could not tell me wha~
was causing the strobing. Then when I called
back to tell them, they could not tell me what
should be there, or why! Maybe some engi-
neer somewhere knows the answer.

PROBLEM
If you have a problem with this supply taking
its sweet ol' time firing up, then change this
capacitor and you're back up and running.
Immediately. (I had one that took 45 min-
utes to start up!)
