OK, I'll explain it another way.

I get a 40 pin male .6" crimp header cable, the type that plugs into a
40 pin socket.
I crimp a 40 wire flat ribbon cable on it.
I crimp a 40 pin female IDC connector the other end.

Looking at the top of this connector, where will pin 1 of the 40 pin
socket line up?

IDC connector        40 pin .6" header to DIP socket
 ======                ===========
| 1  2 |              | 1       40|
| 3  4 |              | 2       39|

etc.

With the connectors available to me, I have found that pin 1 of the
connector on the left mates with pin 40 on the right, so it looks like I
have to reverse the connections on my artwork on the IDC connector.

Am I getting closer to the explanation and the problem guys?
