Casio FX-7700GH Has some marks and tipex on back from age and use, also has some slight rust on battery terminal and batter metal cover. PLEASE NOTE, ONCE BATTERIES ARE INSTALLED THE RESET BUTTON MUST BE PRESSED FOR IT TO START WORKING, ALSO THE METAL CASE NEEDS TO BE PLACED OVER BATTERIES AND LOCK BUTTON MUST BE SLID ACROSS FOR THE CASIO TO POWER ON. Please study pictures. I usually post Tuesday or Wednesday.
