We build Greenscreen 3270, a modern TN3270 terminal emulator for iOS, on iPhone and iPad, and we design custom systems that connect core platforms to the way people work today.
Greenscreen 3270 is a fast TN3270 terminal emulator for IBM Z on iPad and iPhone, designed around the hardware keyboard and touch. TLS, TN3270E, models 2–5 and logon scripts, in an app that fits any screen.
A separate, free-to-download edition that only works after a company sign-in, with central control over seats, host configurations and scripts.
Microsoft Entra ID, Google Workspace, Okta and other OpenID Connect or SAML providers.
Add and remove seats, push host configurations and scripts, and lock settings from one web console.
Designed so device-management tools such as Intune and Jamf can push configuration too.
Beyond our own products, we take on custom work for organizations: connecting legacy and mainframe platforms to modern tools, and building the internal software teams depend on.
