Are you sure about that? I thouht the only difference was that
more wires were connected on the later backplane. You were
supposed to be able to use anything (including a KA670) in
the later backplanes but only a KA670 in the earlier one.

If the difference was physically obvious, why rely on telling
people the serial number range to distinguish one from another
when simply looking would have done?
