I'm not paranoid are you talking about me?  ;-)

Well, if I could suggest something (and why not,
right?) I would want a section for "Neat tricks" where
how certain things are done are explained.  For
example:

In "Fast Food", how did they make the letters for
"You're getting fatter"?  Those ain't playfield
graphics.

In "Space Invaders," how do they do it?  I'm guessing
the invaders are drawn with player graphics, but how
do they move the rows over?  Also, if I hold reset
while turning on the power =:-D I get two missiles,
and the invaders get two missiles, and they all move
independantly.  Where did it come from?

In "Missile Command," how do they draw all the
missiles and their trails?  My only guess is with ball
graphics, but I can't see how--I thought you were
limited to one ball on screen at a time.  Likewise,
"Pitfall" with its swinging rope.  It changes color
depending on the scan line, so I'm guessing ball
again, but how?

In "Asteroids", all those asteroids and the ship with
no flicker until you get over (I believe) 6 asteroids
on screen.  How'd dey do dat?

How about a text document, with JPEGs of the diagrams
that can be downloaded seperately?

Still fighting with his Adobe Acrobat readers,
