Psion Series 5
The Psion Series 5 was a PDA from Psion. It came in two main variants, the Series 5 (launched in 1997) and the Series 5mx (1999), the latter having a faster processor, clearer screen, and updated software. There was also a rare Series 5mx Pro, which differed only in having the operating system loaded into RAM and hence upgradeable. Ericsson marketed a rebadged version of the Series 5mx called the MC218. An open source project OpenPsion, formerly PsiLinux, supports Linux on the Psion 5mx and other Psion PDAs.
