by approximation routines. Some of which came out in EDN or Electronics

Anyone remember the mechanical calculators made by Singer Sewing Machine
Company. If you divided by zero, the only way to stop them was to unplug

The Engineers - (Title ? -- did buildings, roads, Water tanks, everything) had some when
I was in high school. We spent a day there on job interviews - found it to be a ugh job
where 'blue prints' and the brown Van Dykes were state of the art. That end of the room
was foreign smelling to most of us young people. I decided to become the news photographer
when the pro was busy or off.
