Couldn't locate 34 pin headers required for the Axiom CPU header interconnect plugs so we had to modify standard 40 pin units to fit.  A dremel and some Exacto knife work did the trick.  When they layed out this board they sure didn't give any extra room around those headers.  .1" is all you get in all directions.  The inner corners is where the major interference occurs.  Have to bevel the inner edges to allow the three inner most connectors to fit.  Don't loose track of which plug goes where or you will be beveling after all the wires are installed.
