In a Sph. project, we were given a ferrite core (~1 pound) and were told
to use it as a counter, adding up when a new car entered a parking lot,
and subtracting down when a car left. So, doing arithmetic in ferrite
cores has been around for a very long time, indeed. {{OH, BTW, the
purpose of the count was to prevent overflowing of the parking lot}}
