Take a look at Vol. 2, _Accidence and Word Formation_, in
Moulton's _Grammar of NT Greek_ series. Pages 37-114 give a fairly
complete description of 1st Century Greek phonology, especially as it
relates to writing. Moulton was well-versed in the secular papyrii
discovered beginning around the turn of the century, and his
observations rely heavily on that knowledge. There may also be other
resources out there which others on the list will mention.

It is my impression that relatively little attention has been
given to reaching such a widespread consensus.
