You would need something like an IBM SDLC adapter for a PC, or a Novel PCox board (also for the PC) depending on whether it needs to be connected on a SDLC link or as a control unit terminal off of a cluster controler. Problem is there isn't either a SDLC or a CUT board available for the Amiga, however it might be possible to put one in the PC side of an Amiga with a bridgeboard. Is the interface a 25 pin like the Amiga serial port or is it a twisted pair or coax cable? > UNLESS: > Q2: Does he need a "3270" emulator, or an emulator which recognizes one > of the several protocals supported by the new smart IBM async terminal > controllers? This, too, is a Big Difference. Most of the async term controllers > recognize VT100s, in which case several are available; I use VT100 V2.6 (NOT! > V2.9x, which is broken and will _not_ work with the controller - calls to line > 24 end up on line 23) myself, and it works just fine. Some of the new cluster controllers do have ansync converter options and I believe there is a program on a Fish disk to use one of these. However, the ansync conversion is an OPTION so it's worth a try but...
