===Model 1 US===
There are a few different types of power supplies for the model 1. The important distinction is the output voltage: some provide 9V, others 10V. Beyond that, they differ by input wattage, which does not matter to the functionality of the console and only affets power consumption. Check the voltage rating printed on the bottom of the model 1 for the correct voltage before using a power supply you find in the wild.
