Students’ calcs in the 70s/80s

[DA74254]

Calculators were allowed in primary school in 1982 in Norway. Though only from 8th grade (age 14) and as I remember, there were no restrictions whether programmable or not (I think the prices were restriction enough).
I started 8th grade in 1982, the very first year calcs were allowed. I had a Casio Fx-82. (It's been "borrowed" by my sister and it is still with her, functioning, on the original batteries..).
I used this calc throughout most of my schooldays, only to replace it with a HP 28S in 1992 when I started my last year in Ships Engineer education.
At that time, programmable calcs were not allowed, but my teacher said that if I was able to program it, using it and get the correct answers (via the programs), I had understood the subject well enough to not need a programmable calc. Hence, he allowed us to use prograsmmable calcs, and actually argumented with the National Exam Board for the calcs to be allowed.
