Oddities

The great thing about the Psion range of handhelds is the wide variety of software that is available for them. There are the usual games, business software and utilities, however out on the fringes of this are some really unusual and useful pieces of software.

The following are not recommended for the faint at heart:

Linux

Yes, it is possible to run Linux on your Psion but be prepared to trash the contents of your Psion's memory to do so.

Perl

This is just great! This is one implementation that I can say from first hand experience really works. Installed and worked at the first attempt.
PERL 4 Psion

 

Python

More script language rocket science!
Pyton for EPOC Systems

 

Shell5

So you hanker after a DOS interface for your Psion? Well this is for you. With Shell5 you get to type your commands in giving you access to basic file operations, an editor and many other more sophisticated features.
