I just love old calculators, I'm building qute a collection now.
The photo is of one of my oldest which I found in a drawer at my Dad's house. Its gimmick is to use a stylus on a wire to enter the digits, a bit rubbish really and the arithmatic isnt quie right either.
I used to use Casio programmable calculators a lot to work out sun and moon positions, these were always spot on and faster tan some of the alternatives.
Recentley I have bought some mechanical calculators, one like the ones we used at school before electronics were common.
