RE: CASIO fx-4000P scientific calculator from 1986
thanks José, yes, I was pleased to get it for that price. I'd been watching for one for ages, and luckily it was a Buy-it-now so I was able to pounce quickly when I saw it.

That completes my mini 'P' collection (I think): 3400, 3600, 3800, 3900, 4000. Now I need some time to play with them all and work out which I like best.

The 3800 is I think the last of the traditional segment LCD display models, which is the display I had on my Casio's at school, in the 80s, so I have a soft spot for that, compared to the (arguably better) pixel display on the 3900/4000.

But only the 3400/3600 have the a/b/c fraction key, which I also like; shame they dropped it from the later models.

I'm not interested in the later models in this line, e.g. 4500P, as I prefer the silver/beige looks of the above (again matching the scientific Casios I had at school). I think everything after the 4000P was darker?

Although I also have a 700P and a 7000G that I used at Univ. must dig those out for a play, too.
