The "WAS" in that title just made me feel really old. I remember learning about this in college and it being a thing that I would need to work with and understand how it works why it's different than ethernet. And now it's just a big "WAS".
Never ever seen it in my life though. It was a big "WAS" even then.
The i386-i486 machines we had in middle school were on the Ethernet bus (I remember the BNC cable going along the classroom, with T-joints to the network cards).
IIRC Token Ring wasn't a thing in practice for 100Mbit speeds and beyond, and went the way of the dodo faster than DOS did.
Sometime I wonder if any of the old protocols have new merit because of some other advance.
