I expect to get Jim's prototype board that plugs into a LaunchPad today, so I wanted to get everything ready.  I did not want to disconnect all my rat's nest of jumper wires and breadboards that I was initially using to check out the pins for Jim, but luckily I have another new LaunchPad.  Here is the odd thing (which I think Chris has also mentioned).  While the one that I was initially using clearly had headers factory-soldered for connectors J6-J9, they are DNF for the new LaunchPad that I have.  Thus I soldered in headers.  (I only hope they are sufficiently straight to fit Jim's board when it arrives!).  If the time comes when anyone needs to do this, I have a whole box full of headers that can easily be broken to the right length.
