The 2744 was THE PINNACLE of Token-Ring development as it ran at a staggering 100 (yes two zeros) Mbps! I installed exactly one of them for a customer who was using Token Ring. Soon as we upgraded to that machine but before we connected it they dropped T/R for Ethernet. :-)

It also supported 16M (and maybe 4M too, I don't recall.)

I'm quite sure that card would work on a POWER6 with PCI-X slots as it took an IOP to drive it.

For all I know it's still works in i 7.2 too as the CRTLINTRN command is still in i 7.2! AND -trivia of the day- POWERHA supports replicating of Token-Ring lines!

A lot later than I thought.

Two token ring adapters come to mind:
2724
2744
I can find this link about the 2744

PCI cards, February 2007 (updated April/May 2007, April 2008)
IBM plans that the POWER5/POWER5+ based System i models 520, 525, 550,
570, 595 will be the last to support the following older PCI cards. Users
may wish to start moving now to newer technology PCI cards to ease future
system technology adoption. These older adapters/controllers include:

I can't remember if the 2744 was a special token ring card that was mainly
there to support token ring from the FSIOP/IPCS genre of "pc on a card"

I couldn't find anything quite this clear about the 2724.

Looking at this:
http://www-01.ibm.com/support/docview.wss?uid=ssm1platformibmi

I searched for various models and the 2724.
Supported on:
9406-170.

heck with it, I'm going home for Christmas... Happy Holydays.
