Can you get it to do TN3270?
Those IRMA boards implement a 3270 hardware interface...nothing to do with
IP. TN3270 (as you know) is effectively 3270-over-IP.
Ah, right.

I still think that "TERMINAL" is a better name than "thin client"
I'm kinda bummed that I've got an IRMA 3270 card and nothing to to
connect
it to.
The 3270 hardware protocol uses coaxial cables and BNC connectors.
Upstream from terminals and printers are usually found "establishment
controllers", like 3174s, etc. They connect to a host (mainframe) via either
a LAN connection (Ethernet or token ring), serial bisync over a modem or
direct connection, parallel channel (an older high-speed IBM mainframe
controller interface), or some other method.
Interesting architecture!
That interface board allows one to connect a PeeCee (or a Mac, or whatever
it's for) to one of those establishment controllers.
I want to know more about these boards now, did software come with them?
