I finally got all my parts.  I was able to test everything, but ran into some problems.  When I plugged the control board in, the power supply dropped out.  Turns out I used the wrong footprint for the female DB-9 connectors.  I must have use the male DB-9 footprint because the pinout is reversed.  I will remove the connectors, and solder them upside-down instead.  That should fix that problem at least in the short term.

I also tried to solder the pins in for the serial connector.  I ran into trouble here as well.  Turns out I used a 9mm circle instead of a 7mm circle.  I was never 100% on the dimensions for that connector.  So the pins don't fit in the computer connector.  Kind of disappointing.  I will update the layout.  I'll have to decide if I want to make a new set of boards or not.  But I need to finish proving out the rest of the design first.
