Reply to "Turned out to be a Faulty CC-M [Originally CC-M and motor-to-backplane connection questions]"

GRJ,

So I took the (arguably) easier route and swapped the CC-Ms since I didn't notice this mismatch pre-upgrade.  The problem follows the CC-M.

Now, the question is - which one is bad?  Check this out, I noticed something a little different between the two boards...

One is green and one is black/brown!  Now I know manufactures often change PCB substrates and whatnot, but these are likely from different generations.  Both do have the same 2007 copyright year and have a sticker that says "CRM- 6.0" on top of the microcontroller.
