When it finally broke this year-reinforcing my 15 year replacement rule- and couldn't be repaired because Robertson no longer supported it (now 2+ generations obsolete) I went with a Simrad AP25. I finally replaced it about 15 years ago with a Robertson. I had it for many years and it gave good service, although it required more and more TLC each year. I think Bendix may have become Cetrek-Benmar at some time.
I started out in 1966 with a Bendix autopilot.
