Eric..  I wanted to do this too, some time ago, and wound up buying the
adapter.  It serves the C92X and 17Cxxx parts.  I count about 30 traces from
the header (it has a 40 pin dip ribbon header hanging off of it) to the ZIF
socket.  The board is two sided and there are vias.  I would literally have
to unsolder the ZIF and header and reverse the traces.  It may (likely)
damage the plate throughs in the process.  I regret that it is a bit too
much work.  Sorry, bite the bullet and order.
