Thank you Peter Fox. I found a picture of what appears to be a similar heading select system to the 747-367 that the Capt likely garnered most of his flight time on. What I see is a heading select knob with a rotary knob next to it to select the mode. I think you are correct. The operations would be very different with little carry over.
