My memory of token ring is vague, but I think it was originally a ring in series as you said - however token ring switches (that isn't what they were called) also existed, which was the "modern" way of writing up a token ring network.
Yeah, see the pic in the thread. The "switch" (MAU, Media Access Unit) seems redundant to me though, based on what I read I would expect the network interface cards to create a functional ring on their own over a shared medium. Maybe the old cards for ring-topology networks only worked in that one mode and the MAU made them compatible by pretending they were part of a physical ring, cutting computers out of it if they turned off.
Yes, I think that's probably how it worked.
