Condition	For the most part the calculator is in excellent condition. However, the top right edge from the red display cover has broken off. I used some glue to attach it.
Repairs, Comments	Was sold as defective but after I removed the corroded battery pack and cleaned the battery compartment it worked fine with a new battey pack! I cut off the connector of the powr supply and made a special cable that can be used with an off-the-shelf DC power supply.
