Andrew Kay was the son of Russian immigrants and grew up in New Jersey. He graduated from MIT in 1940 with an engineering degree, then he moved to California to work at the Jet Propulsion Laboratory in Pasadena before moving to San Diego County in 1949 to join Bill Jack Scientific Engineering. In 1952, he invented the digital voltmeter to precisely measure electrical current. A year later, he founded Non-Linear Systems. In 1981, Non-Linear Systems decided to design
a personal computer to compete with the popular Osborne 1 portable. Though briefly called the “Kaycomp II,” the “Kaypro II” was actually the first marketed model of the computer. This was because in 1982, a daughter company was organized called the Kaypro Corporation and thus the computer was rechristened with the same name.
