Talk:Parametron

Details needed

How about an electrical circuit with a detailed explanation? The circuit given here is incomplete and shows two ferromagnetic toroids, which don't seem to make sense. Any experts out there, please? David Spector (talk) 23:34, 7 September 2013 (UTC)

Not at all an expert, but I've managed to find some sources that explain things better:

Here's a patent, if that's useful (then again, maybe I'm just link spamming...)

Wording change: PC-1 was not a prototype computer

The computer PC-1, built at the University of Tokyo is referred to as " A prototype parametron-based computer, the PC-1, was built at the University of Tokyo in 1958.". It was hardly a prototype. It served researchers very widely inside and outside the University of Tokyo once it became operational. One of the first open computer seminar was held with hands on programming on PC-1. See, for example, https://ieeemilestones.ethw.org/Milestone-Proposal:Parametron,_1954#The_Birth_of_Parametron_Computer:_PC-1

I would propose to change it to read something like the following: "The PC-1 (Parametron Computer No.1) is a fully programmable stored-program computer for scientific computing, assembled in the Takahasi Laboratory, Faculty of Science, at the University of Tokyo." Basically a copy of the sentence in the IEEE Milestone proposal page. — Preceding unsigned comment added by Zephyrusjp (talk • contribs) 01:37, 14 August 2025 (UTC)
