No, don't try to use the hardware I2C in the PIC's for master mode!   I've
made many attempts at this with the '74 to no avial... finnally figured out
that master mode IS NOT SUPPORTED on the PIC's UART!

You must abandon the hardware methode and bit-bang out to normal I/O lines.
There's an ap-note for this in the handbook.

If I where you, though, I'd buy the MPC "C" compiler from CCS.  They have a
"C" file already written for you to do this.  It's only $99, and it sure
makes alot of codeing easier!  Especially for the larger PIC's!  I have been
using this compiler to interface to a 24LC01 for some time now with no
difficulties.
