When I was young (mid to late '60s), I had a computational machine that I would like to rediscover. I've done the Google thing, but I can't remember its brand name, so I have been fruitless in my search. Maybe someone here either remembers it or can figure out which one it is (I am sure there were a few in the era).
It was made of mainly red and white plastic flat "sliders" and there were metal rods supporting the whole thing.
The slider had small, white plastic tubes to set it up (program it) and they were pulled or pushed in a certain way.
I can't remember how the answer was supposed to be read, but it was just a binary logic machine.
Does anyone remember this device?
This is the Dig-Comp 1 that I had.
This is a new copy.
