Early CoCo2s featured a 'melty' keyboard. There are actually two of them, named for it's beveled keycaps. One versions replaced assembly screws with melted plastic pegs. On that version, the mylar ribbon's output fingers are reversed - on the bottom laid flat (picture 2)
We don't offer a KeyFix for the melted together melted keys keyboard, but this gizmo will let you plug any other CoCo keyboard into your melty CoCo2.
