The slam on the binnacle is known as the "eyebrow dashboard salute".
This is a known problem caused by a pin soldered into the backplane
that's used to support the speedo cracking the solder that holds it to

That is a likely fix but the OP has already replaced the IC and the
problem was not resolved. Still, I suppose the both ICs could have had
the same problem and symptoms.
