Psion Raspberry Pi Pico

Re-creation of Psion Organiser II

In 1984, Psion launched the first practical pocket computer, the Psion Organiser I. Psion followed up with the Psion Organiser II.

Andrew Menadue has a project which recreates the Psion Organiser II with the Raspberry Pi Pico and ESP32-WROOM-32. He has several videos on YouTube and some GitHub repositories. Andrew was nice enough to send me a set of boards, which I’m in the process of building.
