>>
>>54212760
it's designed for people solving equations and not pasting their homework problems

it casts the burden of order of operations from the calculator to the user, but the user shouldn't mind, because he actually knows what he's doing.
Some might say that RPN is a holdback from the days when all calculators could only display 1 line of numbers, but it's honestly more fun and more satisfying to use a calculator this way.
>>
>>54209085
The 35s is one of the few calcs usable for some engineering exams, so it's basically like TI in that it's school-approved.

The 50g is harder to use, but way more capable, than the TI calcs, and HP is pushing a new meme calculator called the Prime that barely has functional RPN (doesn't integrate well, etc).

RPN and RPN programming are basically just assembly language. You put crap in registers and then do an operation. It was much easier in those days to have RPN as your operating method because that's how the simple processors of the day worked.

To have algebraic logic you need some code to figure out operator precedence and so on, for a long time many of even the most advanced algebraic calcs including the TI-58C could only handle three or four nested levels of parenthesis, making the use of pen and paper or scratch register operations necessary for calculations.

The fact that it's also faster and handier, especially for long chain calculations or calculations using a certain number (which you can put in t and pull down an infinite number of) is just a happy accident.

The HP 9100a and 9100b, HP's first calculators (really computers), were all transistor to transistor logic, no IC's whatsoever. RPN was the way to go, the extra logic needed for algebraic use would have filled another chassis at least.

>>54214356

Revealing age but I used an HP48g through college (CS) the the TI89 series came out my junior year if I remember correctly. It is a nice calculator to be sure. If memory serves (and a little of my opinion here) it was the first TI series that had an equation writer/solver that was on par with the 48g. At the time, I think a lot of my friends took to it because it was what they used in high school. The 48g instructions were fairly easy to read...easier than those early edition Deitel Java texts.
>>
>>54214747
Thanks for the answer. I have never used an HP calculator in my life (never even seen one with my own eyes). I was just genuinely curious as to why HP is held in such high regard here. If TI's best is pretty much on par with a retired HP model, I can see why people hold HP in such high regards.

Thanks!

Not once those heat stakes start to give out and the foam gives way.

50g is just built better. I agree that it'd be nice to have the big ENTER key but the pluses of the 50g outweigh the downside of the misplaced ENTER.

It's between three and thousands of times faster than the HP-48 series depending on what you're doing.

Mine creaks when you push the keys.

And it happens to a lot of people, failures due to the heat stake construction and the fact that foam and shit wears out are what take most HP-48s out of service.

If yours is in good shape you're doing great but many are going to fail and require somewhat minor surgery which will mar the case.

What the company that does everything in its power to stop you from programming the machine except in their shitty meme language?

TI sucks for programming, consider yourselves lucky that you can still even program them at all. Once they come up with an improved secure boot system the whole TI programming community will be using out of production machines.

They fell so hard for the education meme that they forgot there were other users.
>>
>>54227065
I'm sorry. HP did the same thing by not releasing documentation. There is no difference between "secure boot" or "undocumented" in my eyes. It's the same thing.

>There is no difference between "secure boot" or "undocumented" in my eyes. It's the same thing.

NewRPL is working great on the 50g hardware anon, it's a whole new OS. The system was apparently easy to figure out, it's a fairly common embedded platform.

IR even works though nothing's really implemented with it yet on NewRPL AFAIK, though maybe they have printing and file transfers working now, it's been a few months since I played with it.

There is a huge difference, though. HP is not taking active measures to stop anybody from doing anything they like with the hardware platform. HP cooperated with the WP-34s project people and even gave out free programming cables and stuff to the team. TI has teams of engineers trying to come up with newer and better ways to prevent you from running anything but their TI brogramming shit-tier 'language' on their machine.

They did by not documenting the hardware. I said it, there is no difference in my eyes.

You can do it whichever way you feel works best but most people use enter. Programmatically they are equivalent, the machine will execute the same instructions.
>>
>>54205955
The 48GX is comfier for use with the 82240B printer, you can hit that thing from halfway across the room!

The HP-50g has much weaker IR, people have found a very high-value resistor in the circuit and replaced it with a lower-value one with success though.

You can do 3D graphing and you have a full CAS on the HP-50g. In fact, before Mathematica

It's handier for many use cases, you don't necessarily want to lug a laptop everywhere just to play with Mathematica.

In fact before Mathematica even existed you had the HP-28c/s which had a CAS as well as graphing capability.
