    The OH-7700 is not only overhead projection model in Casio lineup, as i've seen references to a OH-7000 model, which was obviously the OverHead version of the Casio FX-7000, first graphic calculator.
    OH stands for OverHead, as you would guess, and 7700 indicates that, apart from the overhead features (that consist mostly in a heat resistant design and transparent LCD display), the machine has the same features and interface as the FX-7700.
    The OH machines are not exactly rare, neither are they a Casio exclusive; but the fact that they were released only to the education market make them difficult to find.
