RE: HP-67 bouncing keys
The key debounce is done in software.

It is possible that the key domes have become soft over the years and might feel a bit mushy when a key is pressed. This may lengthen the contact bounce such that it is outside the debounce delay causing multiple key presses to be recognized.

cheers
