When Casio ruled the world

 

Can you name another calculator manufacturer apart from Casio?

It used to be any colour you like as long as its black, but now available in blue, & pink iirc?

Fx-86 today? I still have my fx-85v from my uni days! In a hard case, too!

(Yup, that's "Mint sauce" the sheep cartoon from MBUK)

I remember calculators making their first appearance @ school. Some flash rich kids turning up with things the size of bricks, that could do all 4 functions! 

& Later with scientific functions:-

I wonder what happened to Texas Instruments? That.
