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 :-(
I believe the *Remote* 3174 (et al.) is one of
these devices from IBM.
The bigger 3174s have ethernet as an option, as did the Memorex/Telex 1174
More commonly, 3174s had token ring and people have gone Cisco to 3174 to
get coax terminals talking to Hercules. I believe Guy S., Dave W. and Jay W.
have done this. I have the parts to do either token ring or ethernet on
a 3174,
and just got probably one of the last 1174s in the world with ethernet (but no
docs)
One of my projects is to try to get something similar going that is open-source
which is why I was interested in ajk's arduino project
The documents presented seem to have lots of info. Perhaps I should get the scope out and
see what happens on the co-ax...
