    If you take it down prior to getting an answer you will not get one.

    It is a risk you have to take (or not). I do not think anyone here is interested in helping you using PM. Most often it is a team effort anyway.

    I do not recall a PIC with that number.

    Are there VSS and VDD connections to the PIC ?

    There is an unmarked 8 pin chp that looks like a driver or level shifter. Most often I2C does not use one. Keep in mind the SDA line can be driven by either the master or the slave. That would be a problem here.

    I do not see an ICSP connector. Don't leave home without one :)

    Its a microcontroller

    the unmarked 8 pin chip is the I2C bus buffer.
