Oregon Scientific Osaris PDA Handheld Computer. Very similar to the Psion Series 5 but uses a more recent version of EPOC and has a much simpler and more robust hinge mechanism. Lovely screen and keyboard along with the excellent EPOC software.
This machine has had very light use but stopped working suddenly. Not sure why, it has never been dropped and was just stored carefully in a drawer and is in lovely condition otherwise.
Sold as spares or repairs, hopefully someone will be able to get this lovely machine working again.
Sold with the original Stylus pen which fits neatly in the case.
