WHY GENDER CHANGER WON'T WORK:

I thought about a gender changer until I noticed that the "key"
(blank spot, no pin connector) position was not in the center.

What I've done in the distant past was find a 44 pin header like this:

and just cram it into one of the connectors. If there's a keying pin,
I just remove it from the header.

I think the point here, is that the header is now a mirror image of the
mating connector that is required. There has to be an inversion of the
sense of the connector, i.e. the header has to stick through the back of the
connector before engaging the female sockets, or it isn't a compatible
mate to the cable in the extension-cable sense.
