Psion Series 3

The Psion 3 range of personal digital assistants were made by Psion PLC. The four main variants are the Psion 3 (1991), the Psion 3a (1993), the Psion 3c (1996), and the Psion 3mx (1998), all sized 165 x 85 x 22 mm. In addition, a Psion 3a variant with factory installed software for the Russian language was called a Psion 3aR, and Acorn Computers sold a rebadged version of the Psion 3 and 3a marketed as the Acorn Pocket Book and Acorn Pocket Book II.
The Psion 3 models were a major advance on the Psion Organiser. They had an original way of managing files: the available program icons are shown in a horizontal line and the associated files drop down beneath them. Manufacture of Psion 3s was discontinued in 1998 shortly after the launch of the Psion Series 5 (a Psion 4 does not exist, due to Psion's concern of tetraphobia in their Asian markets) and the Psion Siena. Psion's industrial hardware division continue to produce handhelds running the same 16-bit operating system, some 17 years after its introduction on the Psion MC range of laptops and 5 years after Psion Computer's final 32-bit EPOC PDA was released.
