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?

Thank you!
Probably another little disc ceramic. It looks like one end goes to
ground, so it's either some sort of decoupling or for very crude
debouncing. Draw out the circuit around that bit of the board, and see
where it goes. My first guess would be another one the same as C14.
I bet it's not hugely critical.
