Hi Yorkie.
Thanks for your kind comments on my page - glad it's been of interest.
Yep, the AY-3-8500 really simplified things
Before 1976, the "home" designs were normally analogue - ramp generators and triggers to draw the lines, bats and ball at the right place on the screen.
The PW build was an "act of appreciation" at what was needed back then. Thankfully the pong-on-a-chip greatly eased the problem.
If you want to build it using an Arduiono / AVR processor then I also have a page that accurately emulates the AY-3-8500 (UK and US versions) here:

Also, my (rather sad) TV game collection, most of which used the same chip here: http://searle.hostei.com/grant/TVPong/index.html
Finally, another analogue one, and a re-build of the Atari arcade (digital) version pics here: http://searle.hostei.com/grant/pong/index.html
I've got a couple of the "Paddle Battle" (pong clone) PCBs that I managed to pick up several years ago, working nicely (huge number of chips, fully digital).
... I must be mad
