Yes, all Ti8x models except 89 (and 92 which are 68000 based) are z80 based.
There are already several emulators to compare to.

http://sdcc.sourceforge.net/ ?

I'm not sure if we ever had a ti-specific z80 compiler like tigcc was for 68k-based models, maybe check on http://www.ticalc.org/

The TI-83 was a great calculator.  At one point there was a community
and quite a few games for it :).

The issue with emulating it is that you need a proprietary ROM that
can't be redistributed.  I think the same goes for the other TI graphing
calculators.

Yes, though Ti never caused trouble with this on emulators AFAIK.
OTH they did send a DMCA letter to those who breached their signing process to make their own flash app.
