Hence my comment. It's a matter of what to believe--Motorola or your
lyin' eyes. :)
Clearly, external bus size doesn't mean much in this discussion. Take
the NS32K series--from the -008 to the -032, all basically the same
internally. For what it's worth, WikiP refers to them as the "first
general-purpose 32-bit microcomputer".
There have been a great many bit-serial computers in history,but I've
never heard them called "one bit" architectures. Register length is
similarly no indication as internal registers can be any length and
"visible" registers may not exist at all.

means just what I choose it to mean — neither more nor less.'
