Hello, I trying to divide and categorize casio scientific (not graphical) calculators into some kind of groups or better to say "generations".
For examlple latest of this kind of "generation" are ClassWiz, before then there was ES PLUS and before that was ES... MS and so on.
Please take a look at attached images and comment if you can agree with that categorization? especially in pre V.P.A.M era. I'm not sure especially about older calculators. Also if you know about relase years of these calcs it will be great.
