What happened between 39gii and prime?
Hi everyone here,
It is said that 39gii had been sold very cheap in China(about 10$ USD only) ,because it has a bad-programed firmware and its kit is completely a mess (For example, I can't even transport any program from emulator to kit).So on these bugs made me believe that 39gii is an uncompleted project.I wonder why HP give up 39gii so early.
Besides, I noticed that HP gave up scientists and engineer's market so far,but why?
Hope someone from HP can explain it. Big Grin

Hello,

Prime comes from the 39gII...
Different HW, and updated FW, but it is the same code base.

The main differences: More time to develop, more HW capabilities, color screen.

Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP.

RE: What happened between 39gii and prime?
Just ask Wikipedia:

"Development of a "HP 39gII+", an improved variant of the calculator powerful enough to include a CAS, was almost finished when the underlying processor was abandoned by Freescale, causing the project to be abandoned as well.[3][4] Instead, the calculator concept was revised again and the specs further improved (f.e. color touchscreen, even more powerful processor), which eventually led to the release of the HP Prime in 2013."

If I remember correctly there is an old forum thread where Tim Wessmann states that sales numbers also weren't great because of the lack of a colour screen.

Hello,

Another factor was the fact that the 39gII was designed to be "cheap" as this is "what the market wants"...

But when we released it, and it did not sell well, we were told

"we need something top notch, the market does not care about cost"...

so, here comes Prime :-)

I wrote several articles for HP's online newsletter a few years ago. Among these articles was a set of statistical regression calculations using the HP 39GII. It proved to be quite capable and versatile!!

Quite sad to know that HP flagship is just a pimped-up educational calculator.
Market is changed a lot since the release of 48 series.

Biggest change is back then there actually was a large market.

As for "...just a pimped-up educational calculator" I'd have to say it's quite an impressive set of pimping; it's still unmatched in the market and we're about 6 years past introduction of the Prime...

I am pretty sure that for the major part of the forum and the (potential) users the Prime is the state of art: powerful CAS, a good programming language, excellent hardware specs, etc.
I am not a mathematician, just a chemical engineer. I was born on RPL calculator (28s) and maybe this is a strong bias.
I was tempted to buy one Prime, but after trying several times to use in for my job (as emulator) I can say that its paradigma (apps, confined areas for each app, lack of advanced uom handling) is far less effective than the open and flexible HP48 paradigma. This just for my use. I am sure that for other use it is well suited.
Even the future DM43 cannot replace the 48/50 on my desk.
I would like to buy an hipotetic DM48, based on SX or GX, with modern cpu, more memory ad SD card or USB connectivity.

Hello everyone:
I have read you for years. It is a luxury to read the messages of such trained people in this forum.
I'm mechanical engineer. In our company we have 8 Prime calculators, one in each cnc machine, and another in the technical office. Each calculator has specific applications and utilities for each machine. It is a wonderful calculator. We could not live without them !!!!

Thanks for sharing that. This is a bit surprising, but to me a nice surprise, to learn Primes are being used for hands-on Engineering applications. Maybe sometime you could share one or more of the programs your company has written, as examples of real-world use.

Prime in CNC machines? I thought the CNC machines, that are not exactly that cheap, came with plenty of power in them (Say, at least the equivalent of a raspberry).

Could you share more? Did your team put the Prime in the CNC, did the CNC come with the Prime built in? Are the programs run there done by your team or come pre-programmed from the factory?

I did not know the Prime could be interfaced to command things.


And for the (paraphrasing) "the prime is just a pimped educational calculator". I wish so many things would be pimped in the same way the Prime got pimped from the 39gii (and I have 4 times the hp50G, so I like RPL too).

Wikis are great, Contribute :)

I admit that my phrase may be considered "extreme" but not wrong, according to Cyrille post
It was Cyrille himself who wrote about the relationship between 39g and Prime
"Different HW, and updated FW, but it is the same code base.
The main differences: More time to develop, more HW capabilities, color screen."
We can still debate about the 39g being an educational calculator....

This does not infice that Prime is, imho, the most capable calculator on the market, far beyond 50g,at least for hardware specs.
But for my own specific needs it is quite useless....
