Maker Patrick Doherty offers step-by-step instructions on how to modify the classic Atari punk console with a joystick. Here’s how Patrick describes it:
The Atari Punk console is a classic 8-bit noise maker. It is easy to build and requires very few components- ones that are readily available at your local electronic supplier, such as Radio Shack. The problem with the Atari Punk Console is the interface; knobs can be fun but only keep me entertained for so long. A joystick on the other hand is a much more fun and active way to use interface
Here’s the build.
