Psion Epoc

The most effective miniature business computers

Index to my Psion and Epoc miniature computer pages.

Epoc is the operating system used by Psion computers since 1997, and in some GSM mobile phones in 2001. It is stable, feature rich, runs well on slower, battery conserving CPUs, and has a wealth of applications available. In 1997 Epoc 32 replaced the earlier range of SIBO pocket computers made by Psion since before 1990. Epoc formed the basis for the Symbian operating systems used by the major cellular phone manufacturers.

The eighty or so pages in this section of my web site describe the Epoc based Psion and compatible computers, their remarkable built in applications, and software available to run on them. Think of a Psion as a Swiss Army Knife of computing. Not your first choice for large projects, but compact, portable, and robust, always handy, and capable of handling more tasks than you initially think. Some people run their entire business from a Psion computer.


The built in applications in the Psion and other Epoc computers.
