CAS on Casio vs HP?

If the Algebra FX line runs on an NEC V30, and uses a ROM-based MS-DOS clone, how much work would it be to get the Casio firmware running on a plain DOS machine? Say, a 95LX or 200LX? You'd have to deal with some keyboard mapping concerns, obviously, but you'd have a lot of extra screen space to display a reference or something. If I did the slightest bit of low-level x86 work, I'd take a crack at it myself.

I'm afraid it is too late for that, this model is over 10 years old now, and most of the published hacking information is gone... I find very little (and dated) details in the old forums... but I agree that would be a nice project!
I remember to use that NEC V30 40-pin DIP processor to replace and Intel cpu on one primitive PC in the 80's, what a boost in performance it gave!

I checking now the available information on the French Graph100/Graph100+ versions (which are identical to the AFXZ-2.0+) and even on the color CFX-9970, but no luck so far.
Apparently there was a great and large French community hacking this calculator, so most of the remaining information is written in French language.
