Used HP 27S Scientific calculator with a case.  Everything functions as it should.  Photos are of the actual calculator being sold.  Calculator never opened for repair, but bezel was removed to straighten a small dent above the display to the right side.  Calculator in nice cosmetic condition, no manual included.  Several programs are included for fun, example, and/or utility: (1) Biorhythm (BIOPHYS, BIOEMOT, BIOINTL, and BIOAVG) - calculates a person's biocycles from inputs of a birthdate and a later date, (2) EBAYPR - for an eBay sale calculates profit, selling price, or cost from inputs of 7 of the 8 parameters: profit, selling price, cost, shipping & handling charge (from the auction), postage (actual paid), insertion fee, tax rate, and bank for payment (USA or foreign),  (3) ERTHDIST & ANGLE - calculates the distance between any two locations on the earth's surface and the direction to begin travel from the first to the second from inputs of the coordinates of the locations (see photo for typical distance, DIST[MI]=8594.4962, for LAT1=30.4506°N, LON1=91.1544°W, LAT2=15.1321°S, LON2=30.1156°E - angle of 87.9937°CW from N), (4) MILEAGE - calculates automobile mileage at fill-ups from inputs of MI1, MI2, and GAL, (5) PYTHG - calculates the hypotenuse or a leg of a right triangle from inputs of any two of the three parameters: A (side 1), B (side 2), and C (hypotenuse), (6) SHOP - calculates which of two items is less expensive from inputs of the cost and quantity of each, (7) TAREA - calculates the area or length of a side of a triangle from inputs of three of the four parameters (area and 3 sides), (8) TWODICE - simulates the random result of throwing two dice, and (9) VFHELL - calculates the rigorous volume of fluid in a partially-filled horizontal, cylindrical tank with ellipsoidal heads.  Batteries included to maintain memory.  Hard copies of the programs will be included in case the batteries disconnect during shipment.
