Steve,
These are the Nikons I know have Focus tracking:
F4, F601, F801S, any of the F90 series, F401X, F5, F6, F100, F80, F75 and the F65 should have as it has the 5 point AF system.
For the older F4, F601 and F801S, the manual says that focus tracking is engaged at the lower continuous drive CL mode.
