Manufactured by Diehl, a rebadged version of their top-of-the-line printing calculator, the Transmatic S. A duplex machine with automatic decimal point management, but trailing zeros need to be entered. High speed multiplication and division. True memory. Last printed value automatically transferred to the keyboard. Other Diehl models sold in the USA by Marchant were the Decima (sold as the 212), and the Decima S (sold as the 314).
