I am not sure the APN-1 was ever connected to an autopilot.
The post WWII radio/RADAR altimeters are not normally alive until 
2500'AGL and I am not aware of them be coupled to the autopilot as the 
reading is all over the place as you fly over the changing terrain and 
buildings.

The autoland autopilot is coupled to the ILS/system and 2 of the three 
autopilots must be online for a coupled approach to CAT III.
