A. New Parts
The Asteroids game has three new parts. If you
have worked on Atari games in the past, then you
should be aware of these important differences. The
new parts are:
•
Power Supply Assembly. It covers a wider
voltage range than before, has higher reliability,
a smaller overall size, and all fuse numbers and
fuse amperages are marked directly on the metal
chassis.
• Game PCB Circuitry and TV Monitor. Most video
games to date have used the raster scan method
of display. This game uses vector generation
with X and Y axes to allow greater contrast, a
greater number of moving objects on the screen,
and lines at any angle to be “ drawn” on the
screen.
Throughout this manual, wherever one of these
three new parts is mentioned, you will see this sym
