Maths was never a strong point (I was eventually diagnosed with ‘number dyslexia’ at uni!!) but was fascinated to see a few yards of paper with rectangular slots at the side during a maths class…. and to be told “this is computer paper!”
It seems totally alien nowadays to think that we didn’t have pcs, mobile phones and DVDs back then! We’d only just got our heads round the new-fangled ‘electronic calculators’ – which were mainly used for turning upside down to create words like SHELL OIL (70177345).
