The Victor 83-1421 is a typical example of an early 1970s desktop calculator. The 83-1421 is based on a Rockwell calculator chipset with floating point and memory functions, and has a genuine Burroughs BR13403 13-digit Panaplex gas discharge display. Unlike previous Victor calculators, which used much larger Rockwell chipsets only a year or two earlier, the 83-1421 chipset consists of only two devices: the 10567PD and 10584PB.
