Title
Parametron, 1954
Citation
The Parametron, a logic element using ferrite cores and parametric oscillation, was invented in 1954 by Eiichi Goto at the University of Tokyo. 4,200 parametrons went into the PC-1, Japan’s first university-built stored-program computer which became the nation's then-fastest in 1958. The parametron’s low cost and electrical stability shaped Japan’s early computer development and scientific research, and nurtured the country's first generation of computer engineers.
