Bought a second HP-50G (not Prime). Heaven in the real world :-)

RE: HP Prime or HP 50g
I had the Prime for a couple of weeks before returning it.
Compared to a real (legacy RPN or RPL) HP calculator, it’s a piece of crap despite the color screen and the much faster processor.
Had it been a real RPN calc like the 50g or any previous real HP calc, il would have been great.
I personally hate it.
I’m still using both my HP41’s at home and at work for everything.
The best scientific calc HP has ever made, with the hp50g.
The Prime is a total disgrace to HP calculators.

This is my personal opinion.

RE: HP Prime or HP 50g
I'm just started to program with the hp prime app on android (after having boight it in may 2017). I see that hppl is Pascal like but, maybe I am wrong , the available library of commands (especially related to programming)) seems a fraction of the size of those available for the hp 50g.

I also quickly went through hpcalc and the general software library and I did not spot any library made to simplify some programming procedures (like on lists). I saw a lot of math functions though and that's neat.

Even the manual is quite short (I found no AUR)

So the levels reached by the 50g are really high I would say. Or I am just plain wrong so would be nice if someone would give me some good directions (do other forums on the prime exists that are as active as this one?)

Wikis are great, Contribute :)

RE: HP Prime or HP 50g
I now own both, the Prime for graphics and most CAS tasks, the 50g for some programs, I like squeezing the last byte out, these: get it running with smallest size is fun, and that is what I have those calcs for. A hybrid is what I would like to have, the elegance of the Prime with touch screen, size and keyboard and a fully implemented RPN .

Yes, the Prime would be a very good calc if it had a different firmware. Full RPN/RPL.
Connections to the outside world is also another issue, though... unfortunately...
Maybe some day someone will write a new firmware like the NewRPL on the HP50g.

RE: HP Prime or HP 50g
As far as I know, Claudio said that porting newRPL to the Prime won't be that hard.

he focus firsts on the 50g, because the 50g is still going strong although discontinued.

So, nothing bad. Moreover for programming I won't consider HPPL bad, it is more readable than RPL.

That’s good new!
Everything that is not 100% RPN compliant is not to my liking and I consider it a step back in evolution.

But I hear you.

RE: HP Prime or HP 50g
I would like to buy SwissMicros, but DM15L (I am assuming you are getting the full-size model) costs the same, and (just like a real 15C vs. 11C) offers more memory and more capabilities and you don't lose anything.

Never regretted this decision.

RE: HP Prime or HP 50g
As a side note, the Swiss Micros DM42 is the most capable "key stroke programmable" calculator ever made...

RE: HP Prime or HP 50g
Hi guys

I just bought my HP Prime 2 days after yearning for it (or its predecessors eg. HP 50g, HP 49g, etc) like more than a decade ago - since 2004/05 to be more precise

This is the first HP calculator I have ever owned. Had been using Casio calculators since teenage years.

Glad to able to register & join this forum. Looking forward to learn a great deal about my new "toy" from all of you.

Thank you.

RE: HP Prime or HP 50g
I think the Prime has the advantage in programming clarity with CAS PPL instead of RPL on the 50g in situations where you are generating symbolic structures like matrix elements. For example, below are portions of programs in RPL and PPL on my 50g and Prime:

RPL

“row1” << IF K1 0 >= THEN L3 NEG PUTI K1 PUTI L3 PUTI K1 PUTI ELSE 0 PUTI 1 PUTI 0 PUTI 1 PUTI END >>

PPL

IF A >= 0 THEN CAS(“row1:=[x^3,-A,-x^3,-A]”);
ELSE CAS(“row1:=[0,-1,0,-1]”);
END;

It is immediately apparent what is going on in the PPL code, whereas the RPL code is a bit obtuse.

For someone who has no experience in either RPL or HP-PPL, I would agree. Whatever you do have experience in is always easier to grok. For my part, it's the RPL version.
