I fully agree with those saying that the diagram is at least partially incorrect.

Now, it is true that the question is confusing. Are we talking about a technical derivation or a function/feature derivation? this probably would yeild to 2 different graphs.

Hello

The diagram is not only partially incorrect, it is also missing some rare not well known models. There was for example the HP-25 light, which was HPs early approach for voice entry in the late 70s.



It was of course a direct descendant of the HP-25. :)

I only see a trunc(HP-25)... :)
