Designed to compliment the Pi 400, but also compatible with the Pi4 board
(and probably earlier Pis too), the Plus One ( +1 ) upgrade is designed as
a cartridge that neatly plugs into the expansion connector on the back of
the Pi400, or the expansion pins on the Pi board. The Pi 400 was designed
to be reminiscent of old Acorn machines like the Electron, so we chose a
name that reminds us of the old Electron upgrades.

But what is the mystical +1 ? It refers to other OSs such as Linux or
Windows (ARM version) which can run on Pi. The cartridge provides a
physical hardware switch allowing you to select which OS you wish to boot
into, without needing to re-write (potentially dangerously) critical files
on your SD card. Instructions and files are provided to help you install
this, or you can buy a ready-to-go OS bundle (physical drives) directly
from R-Comp Interactive.

But that‘s not all! The Plus One also includes a real time clock, with
battery backup, so that your Pi400 or Pi will preserve the time between sessions. This is compatible with both RISC OS and Linux.

Your +1 upgrade costs £25 (bare board) or £30 cased, inc VAT.
OS bundles from £65 (depending on size of discs)
Packs with a Pi400 are available from £120
Carriage is charged as appropriate.
