Early CoCo2s featured the 'melty' keyboard. Named for it's beveled keycaps, this early keyboard also replaced assembly screws with melted plastic pegs. And another thing - it's physically the same as every other CoCo keyboard, except the mylar ribbon's output fingers are on the wrong side.
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.
