When the Atari ST first came out, there were people at Atari claiming that it the 68000 was a 32 bit processor. But other people in the industry were literally saying "wait a minute, this is NOT a 32 bit processor." I guess it is a matter of definition. My understanding is that the 68000 can move 32 bits around internally - and that it is a lower external bandwith version of the 68010 or 68020 from what I heard like 14 years ago.
