who can beat this?

My calculator is a Casio fx-81, unremarkable except that I bought it in 1980 before I went to Uni and what's more remarkable is that I only changed the batteries a few weeks ago. Still does the business!

Oh sorry I forget to say that we have a Morphy RIchards toaster that was a wedding present in 1949!
It's a but moody at times,but still makes excellent toast.

Are yes the pocket calculator.

I worker in the aero space industry, and in the course of my work needed to make many calculations that needed trigonometry to work them out.

Before the advent of pocket calculators, we needed to use large Monroe mechanical calculators, along with a 6 inch thick book of trigonometrical tables.

Then came the electronic desk calculator, that was so expensive to buy, they had to make a security cage to go around it.

The scientific pocket calculator then became almost affordable, seventeen shilling and sixpence I think, we then had the opportunity to purchase one for ourselves and have so much a week stopped out of our salary, till it was paid for.

This thread has just reminded me- my gran said she'd had the same sweeping brush for 70 years. It'd had 2 new handles and 3 new heads though.

Is it a big calculator R1Geezer? I was one of the first kids at school to have a hand held calculator (also a Casio) in 1974. I say 'hand-held' but you needed two hands really.
