I was working with PyPy 1.6 at the time on Windows and eventually got
stuck because of a problem with DateTime values not being handled
correctly somehow. PyPy has all the required interfaces to support
PyODBC with some minor modification to the source of PyODBC. My
changes were pushed to my Git Hub clone but there have been several
releases of PyODBC since then. I have not had a chance to get back to
trying PyODBC with PyPy since that post so I have not tracked the
recent changes.
