I took another look at the schematic and your right Rodney.
There is a 4.7k resistor in-line BEFORE the pull-up.   Why
did they do that ?!!  :(((.   All it needed was a resistor in the
100 ohm range to protect that line.
    If the signal was properly conditioned and  buffered then I think
it could still work.  This could be accomplished in the
converter.   The I2C protocol is niether fast nor demanding.
It will take some experimentation to find the
solution  but I think there is a solution.

Still smelling like a rose. :))

Time to STORM THE CASTLE !!!!!
