That's the one. It is still in my sideboard in its plastic sleeve with schoolboy doodles and instructions.

My Casio HS-8l does square roots. Does that make it scientific?

It has solar cells and has never needed batteries. I think I got it in the 70s. Expect it to see me out..

SMP ("Schools Maths Project" IIRC) tables (i.e. a book of logarithms and trigonometry look-ups) up to O-level

And then calculators allowed for 1/2 of A-level basically for the "mechanics" part of the exam papers.

First scientific calculator was a Casio FX502P in 1980 (for afore-mentioned A-levels). Cost an arm and a leg.

This was a programable calculator which I programmed to, amongs other things, play noughts and crosses.

Still in regular use today, in my workshop, which is too dusty to consider running / ruining a computer.

It was the thing that led me down the treacherous path in to software development.

P.S. Any calculator whose result of "1 + 2 x 3" is "9" gets thrown into the bin as not being a "scientific" calculator.
The only permissible correct answer is "7".

It is amazing how few people remember that from school. We once embarrassed our French teacher at the start of our high school lives when he set us some simple maths problems to do (the catch being that the questions and your answers were to be in French). After handing back half of the class' work commenting on how they obviously weren't listening in maths some brave soul pointed out that maybe he had forgotten the maths he was taught. To his credit he did check with one of the maths teachers and apologised during the next lesson to those he'd criticised. Then, without hesitation, he criticised those who hadn't followed the rule and told them they obviously weren't listening in maths! :lol:

I have a slide rule. In getting it out to remind myself what it looked like I discovered that in its box there is an instruction booklet that cost 9d.
I also have book of Log tables with my military number stamped on it.

My scientific calculator hasn't been used in absolutely years.
Even my Garmin will do scientific calculator functions let alone my iPad and computer. What do I need my calculator for?

Dunno, but I use a calculator quite a bit for working out budgets for various things. Just lately it was working the projected cost of lists of new clothes I need because I have lost so much weight. I usually use the one on my tablet or phone, sometimes the one on the PC, and sometimes my little solar one. Nothing complicated or scientific though. Anyway, as for you I suppose there is pride of ownership? :D

You obviously don't need one.

I have one right here beside my computer. It's more functional than a Garmin (and easier to use), doesn't need me to go looking for the app and doesn't occupy screen real-estate like my computer and doesn't occupy desk real estate like my iPad.

They all have their uses mind.

I've got that slide rule and its grey plastic case and instruction booklet. We were recommended to buy them for maths lessons at school in 1972, just before the age of calculators.

Her is a web pic of my first scientific calculator which I've still got in the loft at my dad's. It cost me £29.99 in Oct 1976 and I bought it the day before I went to university.
