What is it?
The Psion 3 and 3a were personal digital assistants (PDAs) produced by British company Psion in the late 1990s. They featured a clamshell design with a QWERTY keyboard, a monochrome screen, and ran the EPOC operating system. The Psion 3 had 2MB of memory, while the 3a had 4MB. Both devices had basic PDA functionality, such as calendar, contacts, and task management, as well as the ability to run third-party software. They were popular among business professionals and early adopters of mobile technology.
It was the third generation of the Psion Series 3, and was a popular PDA at the time, known for its small size, long battery life, and powerful features such as a built-in QWERTY keyboard and the ability to run a wide range of software applications. It ran on the EPOC operating system.

Psion Series 3
In 1991, Psion launched their first clamshell format organiser, the Series 3, which was a major advance on the previous Psion Organiser models. The Psion 3 range of 16-bit PDA (personal digital assistants) had four main variants: 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. Acorn Computers sold a rebadged version of the Psion 3 and 3a marketed as the Acorn Pocket Book and Acorn Pocket Book II.
The machine featured 128K or 256K of RAM, and 384K ROM Psion containing the Psion EPOC operating system, several good office/PDA applications and the OPL programming language. 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.
The Psion Series 3 had two SSD (Solid State Disks) drives. SSDs could be used to store any information normally stored on the internal disks as a way to provide more space for storing information, to make backup copies or a way to transfer data between Series 3. SSDs were also used for software that could be purchased for the Series 3.
Manufacture of the Psion 3s was discontinued in 1998 shortly after the launch of the Psion Series 5 and the Psion Siena. A Psion 4 does not exist, due to Psion's concern of tetraphobia in their Asian markets.
