Then I think... The II Rom won't step or trace FP calls. When you Switch to FP the II+ Rom (F8) Image replaces the II Rom (F8).
As far as I remember, it's perfectly possibly to use the Applesoft ROMs (D0-F0) together with the "Old Monitor" ROM (F8), which has the step/trace routines.
You could load this combination into the language card if you don't have a physical "Old Monitor" ROM.
Maybe the step/trace will step on the toes of Zero Page locations used by Applesoft, though, I don't remember that.
