CAS on Casio vs HP?

[Dave Britten]

So I can't help but wondering... 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.
