update on IBM terminals

Why are these always in the USA? I wouldn't have thought there was much gold in a 3174-11R I think there are only a couple of boards in them. The 3174-11R is normally connected to the host via SDLC and as such isn't usable "as-is" unless you have a Mainframe with an HDLC or BiSync cards. I Think it will take a token ring or Ethernet card and with that it can be connected to Mainframe emulation via TCP/IP. http://www.argecy.com/index.php?p=2389 The terminals are pretty much useless you have a controller (or Mainframe with on-board controller, like the one Dave McGuire has I think) to do anything with the terminals as they have a co-ax port that runs at 1.5MBps (I think that's the speed) and both the physical (voltages, impedances) and logical (protocols) interfaces between the terminal and the controllers is pretty much undocumented. http://www.argecy.com/index.php?pfile=3472 With a controller and TCP/IP they can be used onto Hercules or some of the other Mainframe emulators..
