I started with a token ring card in a Windows/2000 box so I could connect directly. I have also gone via a Cisco router with a Token Ring interface NATed onto my normal LAN.
I now have a 3174 with an Ethernet card but only floppies. I was planning to try moving the card to a bigger 3174 with a Hard Disk (actually an MFM emulator) but the PSU in that has dies..
... just as I got the MFM emulator working :-(

The documents presented seem to have lots of info. Perhaps I should get the scope out and see what happens on the co-ax...
