    Smile Gold in keyboard?

    sure looks like it. Or is it brass/copper? Took apart a very old keyboard and this is what I found.

    Might also be some under the black dot on the board.

    I'm pretty sure that's an IC chip under that black dot - not sure about any gold there.

    I think that is COB (Chip On Board) with possible gold or aluminum wire bonding.
    PDF has a diagram to explain.

    I would leave it as is. Removing it also removes all the bonding wires.
