A new family tree for HP calculators
Message #1 Posted by jose goncalves on 13 Oct 2002, 7:21 p.m.

Hello, friends

I prepared a reviewed version of my family tree of HP calculators. It is available in PDF format at

http://www.hpmuseum.org/guest/goncalv/hptree.pdf

I included all comments made by the friends at The Museum. So, if you have any comments, please let me know. (What do you think of it, Luiz ?)

Right now I have 27 different models in my collection plus 3 noncalculators (HP71B, HP75D and HP85). All these calculators in my collection but 4 are operating and in pretty good condition.

Very nice! Hm... not my intention to be picky, but isn't the HP42S a descendent of the HP41CV rather than the HP41CX?

Regards, Erik
