There's this remarkable Pong simulator working at a circuit level:

It describes how all the subsystem works (horizontal ball movement, drawing the score, etc.) and allows to play with them in the real time.

Fabulous resource, thanks.

I have a pdf bookmarked that walks through the same schematics in a bit of a narrative, calling Pong "THE GREAT CIRCUIT TEACHER" [0] - the only drawback being the poorly scanned in drawing of the sub-circuits. I haven't worked through it yet but combining it with those simulations should be most illuminating.
