How would you interpret the Xerox Sigma instruction set then...
It had LW (load word), LH (load halfword), LB (load byte)
instructions... BUT the address argument was always considered as a
32-bit word (word 1 was 32-bits after word 0).
To actually read a sequence of bytes required using LB with an
auxiliary index register, which identified which byte in the word was
desired.
