Overview
The Parametron, invented by Eiichi Goto in 1954, is a logic element that utilizes ferrite cores and parametric oscillation. It was used in the PC-1, Japan's first university-built stored-program computer, which became the fastest computer in Japan in 1958, significantly influencing the country's early computer development and scientific research.
