HP 67 slider switches and trace trouble

[jftman]

Tony thankYou.
My one other autonomous action was resoldering the two wires back on.
The red one on the left is alone. The black one in the middle is one of three on that contact. The right contact is 'stock'.

Are those proper? I did notice the closeness of the solder glob to the neighboring board.
The wires became loose while handling the board when resoldering the black and red to separate the two boards in the repair routine.

I think I put the other ends where they should have gone, back where they came!
