DigiComp was a mechanical computer with an awe-inspiring 3 bits capacity.
I got one, after begging my father for what seems now to have been a year, then built it, got it to count from 0 to 7 in binary, and pretty much put it aside because I was able to start programming a real computer, with an absolutely astounding 8K bytes of memory. (IBM System/3 model 10, card compiler.)
Still, if it hadn't been for DigiComp, I might have had to find honest work all these years.
