[time-nuts] HP5370A vs HP5370B...

Hi,

I am curious, what are the differences between the A and B models of the
5370 interval counter.  The panels seem to be the same, and the specifications
seem to be the same.  Is the difference noticeable, or just something like a
different processor chip?

Thanks!

I don't know the specifics of this case, but often
the model number suffix was incremented just to obsolete
the existing installed base.  Once obsoleted, the clock
started to run on the support life (typically 5 years).
Keep in mind that ECO's can be and often are applied
to products without incrementing the suffix.  The chances
are like you said, some component went obsolete, and they
needed to do a lifetime buy, etc.
