Victor Comptometer 19-4461S  
Written by Accutron on 2017-05-07  

The Victor 19-4461S is a heavy duty print-only four function desktop calculator with memory. While most competing machines from the period are equipped with a drum printer, the massive body of the 19-4461S houses a Victor-designed 7-pin dot matrix impact printer which generates 5x7 characters. The 19-4461S is based on a 4-chip Rockwell calculator chipset, and is similar in construction to other Victor 1800 and 1900 series calculators.
