It is shown that, for analytic functiions f, systems of the form z'' = f(z, z') and z''
= f(z) cannot produce chaos, and
that systems of the form z''
= f(z, z*) are conservative. Eight simple chaotic systems
of the form z'' = f(z, z*)
with quadratic and cubic polynomial f(z, z*) are given. Lyapunov spectra
are calculated, and the systems' phase space trajectories are
displayed. For each system, a Hamiltonian is given, if one exists.
