Interesting. IBM also did quite a lot of work on FDDI, but that's a very different
technology than 802.5 (and a better one in many ways).

You can find commercial Token Ring cards that support, 4 Mbps, 16 Mbps,
/and/ *100* Mbps. I see them on eBay monthly.
I heard that IBM developed 1,000 Mbps / 1 Gbps Token Ring in the lab.
But that no commercial products were ever made.
Here's IBM's "Redbook" on Token Ring:
"IBM does not view high-speed Token Ring as a requirement for the majority of
its customers, and therefore the decision has been made not to provide 100
Mbps high-speed Token Ring uplinks on its products..."
