This is a SHARP PC-G805 pocket computer. Light operation has been confirmed. I haven't tested all the keys, so there might be some oversights. If necessary, I can check everything! I think it's very rare to have the box, so I appreciate your interest. The screen has some minor scratches, but there's no problem with visibility. Everything in the photos is included. It's an old item, so there is aging, scratches, and signs of use. Please understand this by checking the photos. Thank you for looking.
