For Gauntlet Legends I have a high-resolution control panel scan. A forum member paid me years ago to airbrush out the graphics from the CPO, so I have a version of the CPO with no text as well... awesome if you don't want to use the same control layout.
The original tiff scan is about 60mb, the PSD of the airbrushed version is about 800mb and an output version of that is probably about 200mb.
I don't have the rest of the art though.
