The Psion II Games datapack. Although this is a copy, it DOES boot GAMES into the top level menu (it appears as the penultimate item on the top level menu). The manual is not included (but shown in the photos), and is also available in pdf format on Jaap’s website (thanks to Jaap Scherphuis).
Supplied in a black casing, but can be supplied in a grey casing on request.
The manual can be downloaded and printed for free from
