PETpix video is a system for the Commodore PET / CBM computer that can play video images. The system is developed by Michael Hill (gubbish). He records video with his video camera, then converts the images to PETSCII images on his PC. The PETSCII files are transferred to a SD card. The Commodore PET / CBM computer reads the images from the SD card and displays them as a video.
