Then it'd be a Simon clone :-)

The goal of this machine's design appears to be that it can be built with
stuff laying around the house (paperclips, tin can for the drum, etc.).
There were earlier machines, like the Minivac 601, which used motorized
rotary switches and relays to push the "automation" envelope.

I like the manual paperclip approach, but I agree that a fully automated
paperclip computer would be way cool. Maybe it could powered by a
pull-string gyroscope or a wind-up clock....
