The IBM 3178 Display Station is a monochrome 3270-family terminal introduced in 1984 for IBM mainframe systems.
It features a green phosphor CRT display and is designed for high-reliability text-based interaction with IBM mainframes, typically used in banking, government, and large enterprise environments.
The 3178 supports the 3270 protocol, enabling structured data entry, form-based interfaces, and host-controlled applications. It was widely deployed due to its durability and cost efficiency compared to earlier terminal models.
This model is part of IBM’s long-running 3270 terminal ecosystem.
