Could have sworn that the L 1011-500 had a digital autopilot.
Distinctly remember the (red covered) Differences Manual stating that, along with a little cartoon showing how much weight was saved by replacing analog 'boxes' with digital ones. However it was almost 20 years ago, so maybe I got it wrong. No longer have the books, so can't check.
Direct Lift Control was a beauty. "30/30 Flap, DLC, Alpha Mode" was the PNF call to complete the landing checks if I remember right. Nothing was better than the the L-1011 when going round the corner on the IGS into Rwy 13 in Kai Tak.
The 777 was almost as good, but the never-changing pitch attitude on the Tristar (thanks to DLC) made it so easy.
Still miss the old girl, but kinda fond of my present (very fat) creature too.
