Text terminals, thin clients or PCs?
For most legacy systems, as well as some new systems, text terminals offer significant advantages over thin clients or PCs. These advantages -- simplicity, security, stability and longevity -- add up to a return on investment that exceeds the alternatives. For more information, download our free white paper: "Text terminals, thin clients or PCs? Six arguments in favor of choosing text terminals" (PDF) .
RoHS and WEEE Compliance
All Boundless Technologies text terminals manufactured beginning June 2009 are RoHS compliant. For terminals manufactured prior to June 2009, see our RoHS and WEEE information page for specific RoHS-compliant model numbers and compliance certificates.
