Exactly.
Back around that time I wanted a calculator, but at that price there was no way my dad would buy me one. It was a ̶s̶m̶a̶l̶l̶ fortune back then.
But less than a year later the prices had fallen so much I got one as a Christmas present. A Casio, which still works perfectly today (green fluorescent tube for the display). It changed my life as far as maths at school was concerned, and ours was the first year in which the calculator could be used in 'O' Levels.
