The Hearts of the Super Nintendo
The article explores the internal clock systems of the Super Nintendo, identifying two primary clock generators: a 24.576 MHz ceramic resonator for the audio unit and a 21.300 MHz oscillator for the CPU and graphics. Discrepancies between official documentation and physical findings reveal a missing oscillator and frequency adjustments made via a variable capacitor. Clock signals are divided to support various components, with detailed timing information documented by the SNES enthusiast community.
