Interesting dead end in computer evolution

Someone noticed that had a picture of some kind of computer. Turns out it’s the Parametron. Not a Futurama character, but instead an early (1950s) computer from Japan that I’d never heard of. There doesn’t seem to be much on the web about it, but from what I gather, it used a really freaky design with no valves or transistors. Instead, the fundamental unit involved two magnetic coils and a capacitor, with the binary 0 and 1 values being represented by the phase of the AC current.

In case you missed it: Pearl Harbor

Independent Institute article: Newly released naval records prove that from November 17 to 25 the United States Navy intercepted eighty-three messages that Yamamoto sent to his carriers. Part of the November 25 message read: “…the task force, keeping its movements strictly secret and maintaining close guard against submarines and aircraft, shall advance into Hawaiian waters, and upon the very opening of hostilities shall attack the main force of the United States fleet in Hawaii and deal it a mortal blow…”

Tension mounts

There’s a Prius being shipped from Japan to New Hampshire that has my name on it.
