IBM 3174-01R Establishment Controller for 3270 terminal networks.

The IBM 3174-01R is an Establishment Controller from IBM’s long-running 3174 series, a core component of the IBM 3270 Information Display System. It sits between the host processor and a network of 3270-type terminals, printers and workstations, managing coax attachment and controlling traffic across the display network.

The 3174 family covered a range of establishment and remote controller models built around a common architecture, with the 01R variant sitting alongside related models such as the 11R and 51R. These controllers supported host connectivity over SNA or BSC links and were widely deployed in mainframe environments to extend terminal access without a direct host connection for every device.

This controller is commonly sourced by organisations still maintaining legacy IBM 3270 terminal estates or SNA-based mainframe networks. Tech-Star (UK-based, shipped worldwide) checks every controller before it ships. Get in touch to confirm compatibility with your 3270 terminal network.
