I doubt there are significant differences. To my knowledge, the semiempirical
AM1 Hamiltonian has not been reparameterized (except possibly to correct
errors). IIRC, key additions from versions 6 and 7 have been added to 5.09,
according to the web site. And, when I have done checks using test cases, the
answers (in some cases generated with earlier versions) came out the same.
Except for the expected minor floating point differences, of course.
