The early IBM terminals (e.g., 3270) were driven by a control unit that was in turn connected to the IBM channel interface (Bus-Tag/ESCON/FICON). The control units connected multiple displays. You¡¯ll need an IBM CPU that has an IBM channel interface to use any of those.
I don¡¯t know what more modern IBM terminals use, but I think they still use the channel interface-control unit scheme.

Hi all,
sorry for the offtopic message, not sure where to go with this one, so I thought the smart heads around here might be connected somewhere. I'm looking to get a 70s IBM terminal, either for a System/3, /6, /32, /38 (or contemporary), 3600 FCS, a Display Station (or terminal) for the IBM 32xx, 37xx, 49xx, 52xx, 65xx, or 74xx, or an IBM 5100/5110/5120 portable computer. I'm interested to see how they were built and would like to see how it is to use them. If you know any good places to go other than the website which should not be named, especially any forums that could have enthusiasts of the same hardware, or if you know someone willing to part with one such machine, let me know please.
Thanks!
