This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: took file HP-15C Calculator-horizontal-2.jpg as a basis and inserted keypad incl. silver rim (for this it was necessary to make the keypad absolutely rectangular instead of using its original deformed state from the source file) as well as complete LCD display from second source file HP-15C calculator, power on, showing square root of 88 (24623476512).jpg, then carried out white balance in GIMP and removed distortions, dust and scratches.
