I have included a ribbon + socket for testing the small board with the adt14g
temperature chip. Note that the ribbon has pairwise twists at the socket end.
This is due to the funny mapping of pin 1 onto chip leg one in this
arrangement. I thought up the socket-to-connector trick after the boards had
already gone out. In the real world, you would call this a prototype and do
another round with the pairs properly reversed.
Eventually I will shrink the black tubing over the socket/connector end.

Also, I discovered a true layout error on the little board after they went 
out: there are two traces on the backside crossing each other. I cut them 
apart with two cuts of a Dremel tool, and we'll have to add a wire to 
reconnect the two now-disconnected thin ends.

I rough-cut the bigger boards on a jigsaw. They need to be filed down to make 
them look nice. Note this is G10 - don't breathe the dust - use a dust mask or 
have a fan nearby.

I added a 10-pin connector with a piece of cable. I have 14-pin connectors, 
but they are at BNL.
