If anyone wants to try the TI-92......

There is an WIN 9X TI-XX emulator that can emulate anything from the TI-82 to
TI92 with some exeptions, but you need the ROM images to run the machine you
want/have.

Fortunately TI has put up ROM-upgrades of the TI-92 and TI-89 on it's site so
you can get those (need to fill out some kinda license) and you'll need the
VTI.EXE emulator (look via www.ticalc.org or also aviable at my site) You may
need to rename the ROM-images you got from TI but they do work.
