Psion 3a

[Pocket Books]     [Computers ]

Introduction

I used a Psion 3a, at work, for a number of years until I repaced it with a Psion 5. I have included it in Chris's Acorns to show how similar it is to the Acorn Pocket Book II and how few xhanges were made.

Here are pictures of my old Psion 3a for comparison:

From the outside, the only visible difference between the Psion 3a and Pocket Book is the logos.

Apart from the logos at the top and the Psion key instead of the Acorn key on the bottom left of the keyboard, the only differences are the application names. In fact there are also minor differences in the applications.
