Asm by itself can only be different if the proc is different. all the
TI-8x have a Z80,so the asm is the same. all 4 use LD, INC, SLA, SRA,
ADD, SUB, JR, JP, they all have A,B,C,D,E,H,L paired AF, BC, DE, HL.
both have IX and IY, both have PC, etc.

The difference lies in hardware. For one the 83 and 82 have a smaller
screen. the 86 requires programs to be aware of the fact that memory
works differently. (You can only access 32k at once.) Rom routines are
in different locations across different ROM versions, and rom routines
actually work differently across different calcs.

Aside from the processor, the linkport is also *exactly* the same. if
you have programmed in asm for the linkport, you can virtually
copy&paste the code for 83&86.
