PC-1 (computer) (original) (raw)

The Parametron Computer 1 (PC-1) was a binary, single-address computer developed at Professor Hidetosi Takahasi's Laboratory at the Department of Physics, University of Tokyo, and was one of the first general purpose computers that used parametron components and dual frequency magnetic-core memory. Construction started in September 1957 and was completed on March 26, 1958. The PC-1 was used at Takahasi's Laboratory for research related both to hardware and software and the researchers in the Faculty of Science also used it for scientific computing. The PC-1 was retired in May 1964.
