Dual core computing engine
At a garage sale today I picked up this:
I had a mechanical calculator similar to this when I was a kid, one with I think more digits. You enter numbers with a stylus to add and subtract. With my old one if you wanted to multiply or divide you were basically out of luck. This one can do it though. How? Flip it over and...
There you go.
Okay, a Curta it ain't, and I'm sure K&E lost no sleep over this thing, but for fifty cents I figured I'd take it home.
