Soooo..The word from Casio is that the keys are different on each calculator (no kidding).
YouTube posters have stated that the programs on each calculator are similar however.
I wanted to buy the Casio Workbooks sold on the Casio site.
I'm looking at the Casio fx-9860G II workbooks in particular as they are cheapest.
Are they compatible with the Classpad 2 400??
