    Color Classic no sound output via internal speaker or headphone out but issue is NOT analog board.

    What is a Performa 450 Demo Unit and what is this weird layout/component?

    I’m afraid I have no idea, mission was to recap, and maybe remove wire from egret, and see if it still functions. I think at this point I will leave as it is.
