random Q from a non-list member...

Hi everyone!

I'm in the process of reviving an Atari pong system circa 1975. It's  
actually a tele-games pong (Sears branded.) All the circuitry is  
Atari, of course.

Can anyone point me in the right directions for schematics for this  
beastie? Does anyone even have one and can just tell me what resistor  
or cap or other fun toy is missing from C15 in this admittedly huge  
graphic?
