Hence my comment. It's a matter of what to
believe--Motorola or your
lyin' eyes. :)
FWIW, when it came out, and for some years after, we were all talking
about "Motorola's (new) 16-bit micro", and when I attended a later
ComputerSci course on 68000 architecture and programming in the 1990s
the family was still treated as 16-bit until the 68020. The first THREE
implementations are 16-bit as far as I'm concerned.
