Hey Chas, how do you feel about the Baroque period ?
Fiddle-dee-dee. If it ain't Baroque, can you fix it?
I had a 600EX long-cage rear derailleur on a bike for a while. The "hatch-plate" mechanism and minimalist inside cage allowed the chain to jump off and spin the lower piece of the cage around. It did this to me a couple times before I tossed it in the trash and replaced it with a SunTour.
I like newer Shimano stuff a lot. Early '80's Shmano? Not so much.
