| Professional applications for the HP 50g|

some might remember my presentation I gave at HHC 2011 or have seen it on YouTube
HHC 2011: HP 49g+ / 50g O.S. Extension Pack
In this presentation I said:
"Minimum development effort needed to create customized and professional solutions targeting at different industries through specialized equation libraries (e.g. Mechanical Engineering, Electrical Engineering, Civil Engineering, Chemistry Engineering, Petroleum Engineering, Physics, Statistics, etc.)."
A first attempt toward this is a professional data set for the TreeBrowser (first presented at HHC 2007) with over 500 Electrical Engineering Equations (including variable descriptions, units and pictures) covering the undergraduate curriculum for electrical engineers in most universities.
A preview of it is available at my website
As an aside remark:
Some "old" fellows might remember the plug-in cards by Sparcom for the HP 48GX or EE pro by Sparcom / da Vinci which were - amongst others - a reason for the success of the 48 family (and which are still sold today).
Ironically EE pro is available for years with any sold TI-89 / TI-92 Plus / Voyage 200 and guess which company took HP’s position in the calculator market (which they gave up without any needs (as we all know), by the way) ?
And there is nothing in regards to software from HP for their graphical calculators as there is from TI at their website:
Some might also remember that there was an attempt to bring EEpro to the 49g+ in 2006, but eventually it never happened.
Now, the Electrical Engineering data set for TreeBrowser will not be as functional / powerful as EE pro was for the 48GX. But missing things could be added ...
Also note that my code is totally unrelated to any existing HP 48 / HP 49 software - a data set is just a bunch of lists. Creating a data set is not sorcery, just labor-intensive.
Feedback and suggestions are welcome.
P.S. This is not meant as an advertisement. It is meant of what is *possible* now with the existing platform and that improvements could be done *fast* and *easy* which I have shown already with my 'MultiLanguagePacks', the 'O.S. Extension Pack', the 'HELP for *all* commands incorporated into the O.S.' and now with this Electrical Engineering data set for my TreeBrowser (TB is included in the MLP / OSE).
Now, given the fact that the HP company has known this for years, but did not had any interest in updating / improving their top-of-the-line machine remains a mystery to me. What’s not surprising is, that they keep loosing market-shares (according to NPD, HP's share in the graphing calculators market is less than 5%)
The new platform of the HP39gII is interesting, but the 39/40 series were always "closed" machines (much more closed than open) and this is still light years away from the functionality the HP 50g offers. And if it breaks compatibility then things won’t become easier. Last but not least: What will it cost at which estimated ROI compared to updating the existing platform ?
And continuing in rushing out immature and buggy products (although common nowadays) looks rather like milking the cash-cow-customer instead of bringing quality products to loyal customers.
P.P.S. Since this forum is - at least - still read by HP people, there is no excuse for not doing anything ...
