Indeed, I suppose it would have been useful — all those programs asking you to select [C]MP or [R]GB on the startup screen, having to always remember to type “RGB” in BASIC to get the palettes loaded, having to type “montype x” in OS-9 (though most of us just automated that). I never saw it used — is it even wired up?

And, does that mean this pin is available for input? :)
