Am I right so far in saying the first is right and >the second (what I used to think) is wrong? They're both wrong. 68k instructions can be 1, 2, or 3 16-bit words long, although I'm pretty sure that only the 68020 and 68030 support the 3 word long ones (CAS2 and LINK (long) come to mind). Some 68k instructions (mostly integer arithmetic) can use byte, word, and long word operands. -Jonathan
