RE: LZ: RE: TI-86 and shells
It certainly would be harder! More will be different than just ROM calls.
Memory locations would be different, etc. It MIGHT be possible to make an
emulator to execute the most basic of 85 ASM programs, but most ASM programs
rely on certain things in the TI-85 in one way or another. Simply displaying
text to the screen requires setting numbers in memory, and these memory
locations are probably different on the TI-86.

Well, the 86 is just an 85 that has been pumped up with some memory and
some other stuff. It sill runs all 85 basic stuff, it can link to an 85
without problem. So adaping a shell ot the 86 wouldn't be harder than
doing it for a new ROM version (which has be done many times)...
