Anybody here ever mess with Tokenring Nubus cards?

At this point I have 3 different Nubus TR cards that I am going to integrate with some Thinkpad laptops (PCMCIA) and some old IBM PS/2 MCA machines using an old Novel server or maybe OS/2 server to bridge to TCP/IP ethernet.

After reading all the stuff Apple put out in magazines when the Mac II hit the scene I figured it would be fun to try it out. Seems rare to have TR on a Nubus 68K mac.
