Rudys Retro Intel | Revolutionizing the Commodore PET with External Video and Audio @RudysRetroIntel | Uploaded March 2023 | Updated October 2024, 1 hour ago.
To help diagnose Commodore PETs like the 2001 and 4000 series computers, I have created a board to provide external video. This helps to determine if the issue is on the computer or analog board within the monitor. Plus saves the built-in monitor from frequent powering on and off.

I have also added the output for audio and a joystick port. This is still a work in progress, so join me as I demo what it does. Stay tuned for updates.
