I've been trying to get my IBM 3174 establishment
controller (to which my IBM 3179 terminals are connected) communicating with the Hercules

I wanted a more immersive feeling of actually using a mainframe than using TN3270
emulators. They just didn't CUT it (little pun there).
After much grumbling and pulling out what little hair I have left, I finally managed to
get everything working as evidenced here:

The real challenge was getting the 3174 configured as there are literally 100s of
configuration questions that need to be answered correctly. The configuration manual for
the 3174 is 800+ pages and the questions from the configuration utility are of the form
Q110: ___. You *really* need to read and understand how the 3174 is set up in order to do
this right (along with filling out what seemed like 100 worksheets).
The big breakthrough came when I figured out that the 3174 was complaining that I
didn't have enough memory for the configuration I was specifying. It seemed odd,
since I had 4MB of memory...the max on most 3174s (some could go as high as 6MB). After
finally cutting the configuration down to the absolute bare minimum I was finally able to
get the "Connection Menu" to show up which allowed me to select from the
configured hosts.
For those paying attention, the 399 on the 3174 status display is indicating that the
SDLC link is not connected. I don't particularly care, so long as the ethernet and
TCP/IP work. ;-)
If there are others on this list that are trying to do the same thing and haven't
made progress, let me know...the details are still fresh in my head. ;-)

I have two of the Token Ring units in stock to give it a try. I should
dig out the pile and hook up what I have.
I bought a Cisco Token ring router which I need to configure, as I
initially used a system with a Madge card. I figure the Cisco will be
more compact.
I have your thread (I am guessing you are the one with the recent
thread) on the Ibm-legacy group, as well as Jay Maynards and Mike Ross's
notes on getting a 3174 to work.
Good to see you got it going.
thanks
