The Psion II Portfolio datapack. Although this is a copy, it needs SHARES inserting into the top level menu, like the original. The manual is not included but is available in pdf format on Jaap’s website (thanks to Jaap Scherphuis).Supplied in a grey casing, but can be supplied in a black casing on request.
The manual can be downloaded and printed for free from Jaap Scherphuis’ website (jaapsch.net/psion).
Many thanks to Martin Reid and Jaap Scherphuis (and others)!
