The first microcomputer: The transfluxor-powered Arma Micro Computer from 1962

I imagine the civilian equivalent in size and structure would be a PDP-8/S (bit-serial, still discrete logic?) But DEC material from that time simply calls it a "small-scale computer".

There's not much information about transfluxors available, although a patent for them goes into quite a lot of technical detail, and is referenced in the Wikipedia article.[0] If anyone knows more about this, the Wikipedia article is definitely in need of expansion:
