Psion organisers

The Psion Organiser was the brand name of a range of personal digital assistants developed by the British company Psion in the 1980's

Early Psions are very robust (as witnessed by tech support people who were able to retrieve data from machines run over by cars and even forklift trucks) and they have been sold in very large numbers (about a million). Some continue to be used commercially, although the firmware of the two-line models fails to acknowledge dates after the end of 1999.

The name "Organiser" was not used for later Psion handhelds, such as the "SIBO" family Psion Series 3 and the 32-bit Psion Series 5 machines which were of a clamshell design with a QWERTY keyboard. In terms of hardware architecture and operating system had no links to the earlier "Organiser" range, other than the end user programming language which shared a great deal of structure with OPL.

Production of consumer handhelds by Psion has now ceased; the company, after corporate changes, now concentrates on hardware and software for industrial and commercial data collection applications.
