I had something like this, but it was called a Digi-Comp.  Don't
remember when it was but it had to be before 1970 -- probably between
1968 and 1970.  Previous versions had used rubber bands to work it,
but this was a new version that used tiny springs made out of thin
copper wire, and they broke or got lost easily.

I never really understood how it worked.  I got it to do what it was
supposed to, but I didn't understand why.
