Problem solved.  Transients were the problem, and putting surge protection in the lines between sensors/IO and the board has solved the problem.     Methinks the WC boards might need some better IO clamping/isolation.  Definately something to look at for WC32 if/when it comes out.    

Boards are OK (I've swapped boards with a known good one, and the problem follows).

Firmware is 3.02.17a.  Power supply is a 10AMP,9vdc industrial power supply, that's supplying two other WC's without problems (I really think it's a noise issue on a data line, I just haven't been able to narrow it down)

Agree with everyone else that the current connection method is a PITA.  What I would love to see in a future design is an option with a 50-pin AMP connector so we could use ready-made cables to a 66 block and punch everything down (or for those who don't do punchdown, a fanout cable to a screw...
