Series 5mx PRO © 1999 Psion.
The Psion Series 5mx PRO is a professional variant of the Series 5mx, released in limited quantities for business users.
It is technically similar to the standard 5mx, featuring the same ARM710T processor and EPOC32 operating system, but includes expanded bundled software, increased memory configurations in some versions, and enhanced enterprise-oriented tools such as improved security and data management applications.
The 5mx PRO was aimed at corporate environments requiring mobile productivity, offering a more complete “out-of-the-box” professional solution compared to the consumer-focused model.
