Palm M100 Vintage Electronic Organiser parts or not working SEE DESCRIPTION

found whilst clearing out my dad's stuff. it's just the organiser, I don't have any cables or a stylus for it. I tried putting batteries in it and it didn't turn on, the battery well looks slightly green on one of the parts, so it might be for that reason. It's sold as parts or not working. please go by the photos and make sure you're happy as I don't accept returns. any questions please ask
