This is a SHARP pocket computer, likely manufactured after 2007. I have confirmed its operation by running a simple program and verifying that character input and display work without issue. However, I have not confirmed that all functions are working correctly. A protective cover is included. The case and internal components of this item have been cleaned. A buzzer has been added during the cleaning process, allowing sound to be produced with the BEEP command. In addition to the main unit, a cover and instruction manual are included. There are minor scratches and dirt on the exterior. Please check the photos for details on the condition. It is currently operational, but due to its age, I cannot guarantee its functionality after shipping. Please feel free to comment with any questions before purchasing.
