Here is the schematic diagram for the original arcade version of Pong, the first digital video game. Unlike other video games of the time, Pong used an all digital circuit to produce the graphics, sound and game control. There is no software or processor, just a collection of 66 discrete chips performing a single function, inter-connected to create the game we know.
For the home version, a single specialized chip was used to replicate all of the functions of the arcade version.
The different sections have been colour coded. As you can see many of the part annotations are very hard to read and copying artifacts obscure many details.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
