I have one of these boards fully stuffed.  I dont see the U5 pin-12 error.
Pin 12 connects to a pad right next to it that has a jumper to the ground
bus down the middle of the board.

I havent spent a huge amount of time trying to make it work yet.

The saddest part about this, following my long-standing rule of making the
front panel/case/whatever first ( got tired of piles of stuffed boards around
waiting for me to make enclosures ), I made the enclosure first and its been
sitting here taunting me for about a year now...
