At that time it was on on sale far below Amazon´s going price range. I believe it was priced so low because 1) they/HP had way too many of these units in stock and 2) because a decision had consiously been made by upper level HP management to get rid of this entire line of Algebraic-only type calculators (like the HP30s, etc.). If 2) was indeed the situation, I agree with the decision on their part completely. There were decisions made then about creating a whole line of similar HP calculators that were bad decisions in my opinion too. Thankfully that group (management and calculators) is gone and an effort is now being made at least to bring back what they have been traditionally known for in the remains of the handheld calculator world- Quality engineered, great products which will last a very long time if treated with some respect. Hopefully with the addition of the HP35s with both the EOS (the Equation Operating System) as well as RPN (the Reverse Polish Notation Operating System) some two years ago and recent comittments to make the very small HP QuickCalc in an RPN only version too, they are now on their way to restoring the tradition for their future development as a quality company for this once very large marketplace item. Sentry in fact now makes such a low-priced graphing calculator machine (available for as low as $21.95 in stores) so if HP visits this marketing option again they better be prepared to also compete in today´s marketplace.
This machine was so very bad (even if it did indeed provide very very simple graphics at an extremely low resolution and at a very slow plotting rate as well) that when I offered to even send it back to HP at my own expense (because I was so very disappointed), they asked instead for me to to donate it to my favorite charity! For example, it had very few and quite limited plotting capabilities and users could not even have the ability to make their own choices or to try to change factory settings and other necessary control options. There were also no self-tests available to make sure that the machine if briefly acting strangely was working properly either, tests which have become standard on all quality HP calculators from almost their very beginnings. It was a decently made machine and very small and light to be sure, but the available math capability was about at the 9th grade level or even lower. Perhaps students at that level could have fully appreciated it (at least students that were mathematically very challenged who might have really appreciated it), but all I wanted at that time was a relatively cheap, graphical plotting machine that also didin´t cost as much as the famous Texas Instruments, TI-83/84 series. However the HP9G was not marketed by HP as a Middle school level plotting unit either.
. And summed up by saying HP 9G: A very sorry excuse for an HP graphing or scientific calculator. Currently HP 9G Scientific Calculator has an overall rating of 6 over 10.
