No, but I imagine somebody here will let you know.  I bought mine (a
net4801-50) at about the date Soren mentioned, so I didn't have to check
that mine was an earlier model.  I know that the -60 version was not yet
available when I got mine, but it may not be much newer.  I assume the
revision number and date are printed on the board itself, but don't have
one here to see where.
