Re: I found it! A very sorry looking MK14.
It's just a trick of the light, those vias have not been touched. The 'hole' is just a dent in the solder, probably exacerbated by my prodding it with a multimeter probe.
Have you noticed the two sets of extra holes at the bottom of IC12 & 13 ?
It looks like they used an 18 pin template for a 16 pin chip.
