Former owner tried to open the calculator. I have taken photos of how that part of the calculator looks. There is black electrical tape around the AC Adaptor and the adaptor has been opened. Please see photos for for a view of the damaged areas. Basic instructions printed from the computer are there. For a detailed instructions they are available online. I will provide you the link with your purchase since eBay doesn't allow me to put external website addresses into listings. Everything works fine on the calculator.
