especially given what I paid for my 48GX, as I wanted one of the last with the black LCD

(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!

It was groundbreaking. The 7000G was the first graphing calculator brought to market!

180? crikey! that makes me feel better

I thought the 7000G was the first, thanks for confirming.
