Galen,
Thanks for the offer.  Yes, I do still need one.  Is it at least 8 inches long?

The IDC DB9 is clearly the explanation for the "crossed" wiring.  It
is scary to think that little hands soldering 9 leads is cheaper than
clamping an IDC closed.   Could it be that the IDC is too wide for
mounting on a ATX case bracket?  Or maybe the connector itself is more
expensive to make?  Can the molded style be wired by robots?
