For example, the HP48G series was a direct descendant of the HP48S series, and the HP49G of the HP48G series. Is there some place where I may find the entire family tree of HP's calculators and handhelds?

Wow, that would indeed be interesting to examine.

You will need to clarify what you mean by "direct dedcendent" though... (emphasis addded) For example, the HP-38 family (all the way to the 39/40GS I think) are all RPL-based internally, but are vastly different from the 48/49/50 series. Are these descendents?

And both of these lines follow from the 28 series. As were the 18C/19B/19BII.

And all the Pioneers too.

And RPL evolved from the 71 Forth ROM.

So it depends on what you mean by descended.

But real interested to see replies here.
