Default PCB of garage door opener failed: Which PIC is this?

On Fri, 09 Feb 2007 13:37:10 +0100, Joachim Wunder
put finger to keyboard and composed:

might the 16-pin IC a I2C maybe? If so, which
ones were commonly used to control an Intel 8748/8749 ?


There appear to be 8 or so interconnect pins at the RHS of the 16-pin
IC. Can you trace them to the uC's pins? Do they go to the data bus,
ie pins 12 through 19? Which pins are power and ground? What is the IC
to the right of the relays? Which chip/component drives the relay
coils?
