(EDIT: There also seems to be a fx-3600PV (with a capital V) that doesn't have the bitwise operations, just to confuse things further! EDIT 2: That one seems to be a fake Casio according to this.) Somewhat annoyingly, I bought a fx-3800P from a major UK stationers back in the day and didn't discover the lack of bitwise operations until it was too late.

sigh; I'd not really looked into the Pv models, assuming them to be non-UK, on which I was concentrating. But now I think I will have to!

I think the fx-3600Pv (the real one, that is) probably was non-UK although the user manual was printed in at least English, Spanish, French, Chinese, Korean, and Indonesian. Some of the images of the (real) calculator I have seen have "H.K.E.A. APPROVED" printed on them (and so do pictures of the fake one), suggesting it was sold like that in Hong Kong.

Indeed; I've always thought the Pv models look a bit garish, with all that "SUPER FX" etc, compared to the more restrained design of models sold in the UK (at least, the ones I was used to).

That said the 3400P looks a bit different, too. And those rubber buttons, sigh.
