Psion

Historia

The Psion Organiser was the brand name of a range of pocket computer developed by the British company Psion in the 1980s. The Organiser I (launched in 1984) and Organiser II (launched in 1986) had a characteristic hard plastic sliding cover protecting a 6x6 keyboard with letters arranged alphabetically. The Organiser II can be considered the first usable PDA in that it combined an electronic diary and searchable address database in a small, portable device. Production of consumer hand-held devices by Psion has now ceased; the company, after corporate changes, now concentrates on hardware and software for industrial and commercial data collection applications. On an episode of The Gadget Show (first aired on 30 March 2009), the Psion was pitted against the BlackBerry for a place on the shows Hall of Fame.[1] Whilst the Psion was highly praised as a device that pioneered portable computing, the accolade was ultimately given (by host Jon Bentley) to the BlackBerry.

Historia

With the release of its 16-bit architecture, Psions consumer and industrial computer designs diverged. The Psion HC was the industrial counterpart of the consumer-oriented Series 3. The HC retained the vertical design and alphabetic keyboard of the Organiser II computers, while using the same 3.84MHz NEC V30H processor as the Series 3. The screen resolution was 160x80 pixels. Three models were available: the HC100, HC110 and HC120, with 128KB, 256KB or 512KB of RAM.The HC was designed to be used with bespoke software packages, and lacked many of the user-friendly elements of the Series 3. It replaced the Series 3s built-in graphical software with a simple command line, and thus lacked an editor for the OPL language. It could run OPL programs, but not those which used GUI elements like windows, dialogs and menus. The basic graphical facilities were offered, but this incompatibility with the Series 3, and the industrial environment that HCs were sold into, meant that little or no entertainment software was written for them.
