The Casio fx-115ES is probably one of the greatest calculators known to mankind. It's unbelievable that I haven't had a single professor that wouldn't let me use it.
>>54094738
can you program it?
Just bought a HP 12C earlier today
>>54094584
>babbies

>>54094584
I see the HP 16C is missing here
>tfw national standard won't let me program it
I wonder what kind of hardware these run on. Probably a shitty microcontroller.
>>54094584
That 912ES looks like a mix of 500ES and 570ES
Casio is best
>>54095603
>>54095693
What's the difference?
>>54095718
Difference of what?
I lost one and bought another one and then I found the old one under my bed, so now I have 2 functionally identical calculators.
I wish I could disable the answer convert mode, because usually, I'm just looking for a number, not a fraction.
>>54095768
No line output mode?
>>54095745
Between both calculators they look identical except for the name
>>54095693
This is the only correct answer
>>54095892
They are, except one has a solar panel.
>>54095881
>>54095881
it's there, but it also disables the textbook entry mode, which is really nice btw
>>54094618
Why are you on /g/?
Nothing compares
>>54095934
That board looks a lot more expensive than that calculator
>>54095934
i wish that calculator came in better colors, i can only find it in faux silver
>not using your phone
>paying $15 for a dedicated calculator device with an abysmally slow epoxy glob instead of a quad-core ARM CPU for doing calculations
Post yours.
>>54095902
Also, never really got the point of solar panels. Been using mine for 4 years, battery still going strong.
>>54095917
Well that's too bad. Casio let you do that.
>>54095934
Casio have way too many models.
And they're almost all the same, just with different hardware locks.
>>54095978
I got it from a school that was about to recycle it. It's old and I don't know how to use 90% of the features it has, but at some point I'm sure it way really expensive (800-1200 range it think)
>>54096062
Does casio even make their own calculators?
HP makes some shitty low-end school calculators that are 1:1 functionally identical to casios in the same price range.
>>54096058
There is not a single android app that can compete with my 570ES.
Every one of them is shit.
And no I don't care about graphing.
>>54096086
Pretty sure they do. They buy controllers, write software for it and stick it on a PCB.

If there's anything that's too advanced for a scientific calculator you'd do it on a computer or a real graphic calculator any way.
>>54096086
They're functionally identical because HP bought some Casio designs and rebadged them poorly. The HP 300s is actually a fx-300es with less responsive inputs.
>>54095934
I too prefer my Casio to be white.
>>54094618
That's nice, remember to add white Cheddar to McChicken.
>>54094584
What's with the TI hate? Sure, they've cornered the market in a disgusting way but their calculators (especially the nspire line) get the job done and done well.
>>54096353
Overpriced I guess.
It has the hardware of a Gameboy and sells for $50.
>>54096364
>$50

>>54096353
they're expensive, underpowered, and their programming language sucks major ass.
It's truly disgusting that TI is still allowed to sell calculators at a 66% markup and get away with it because their calculators are mandatory class prereqs.
>>54096371
For that you can buy 5 570ES in 2011.

>>54096384

Dude if I wanted to program I'd get a computer, not a calculator. Also, Nspire lua programming is comfy as fuck and it has enough resources to be useful. But I don't really want to start an argument so to each his own I guess.
>>54096399
>Dude if I wanted to program I'd get a computer
Because having a Turing complete computer in your back pocket that can run off the same set of batteries for months would never have any use.

>owning anything other than a ti-89
why
HP 20S and HP 10B - really comfy!
I currently have a casio fx-300ES beside me. Not the best in the series of rom 18 calculators, but I like it. The "r" exploit and soft-upgrade trick is quite good fun, and may allow for arbitrary code execution (which I've been looking into). Pic very related, it's the screen of the calculator part way through the exploit and upgrade (captured from an emulator, but it works on real hardware).

>>54097496
I remember back in grade 7 we would perform a series of operations to have our 570MS flash nonsense on the screen.
Years later, when I thought back about it, it's interesting that there are people out there looking for bugs on these devices. I wonder how they managed it.
There was also a hardware trick to switch the 500MS to 570MS mode.
Is there a place where I can find information on these calculators?
>>54098083
Yes there's a big ass Casio forum. Just Google for it anon..
Fuk u they are really good
can someone explain to me why graphing/scientific calculators are so expensive? for the same price these days (in my country at least) you can buy a cheap smartphone that cando all the same and more, the only difference being that you can use them in tests.
fite me
Why are calculators so expensive?
>>54097988
Post more pics man, I was the anon in the sci thread who was talking to you there.
I have a 50g and a Prime on the way. (I know you recommended against it but I've been reading about them releasing updates that fix problems and add new features, while the 50g is stuck as it is; since I have the money I got both and want to get more as well since I've been reading about them non stop).
Pretty hyped.
>>54098645
I think it's just because they can charge that much and know people will buy them.
They're awesome to mess around with. I run matlab, derive, python and C and yet insist on buying them because a dedicated high quality calculator has its own charm.
>>54094584
> needing a calculator
there's like nothing on there you can't do with a symbolic function and 3 keystrokes on a generic scientific calculator
Glad we're having another one of these threads....
Who here has a DM15L from that swiss company? I'm considering getting one because I want a smaller RPN calculator and don't want to pay $250 for a slower 15C.

Hi folks. I am about to buy a hp 50g or ti-83 plus, to replace my bootleg casio with. Anyone here could tell me the pros and cons about them ? Which one should I buy ? I am studing business related math tbqh, so the 50g would be kinda overkill or would it worth the extra 30 bucks ?
>>54102360
The 50g is only 45 usd at the moment and it will be discontinued soon so get it if you can.
There's another anon far more knowledgeable than I am when it comes to calculators so hopefully he can help you out better.
the amount of shitskins on my /g/ is distressing
>>54102360
HP50g:
+ cheap af right now
+ RPN or algebraic (you can choose)
+ powerful ARM chip
+ powerful & efficient programming in RPL
+ CAS (symbolic solving & calculus)
+ unlimited precision numbers
- you have to read part of the manual
ti-83 plus:
+ they will teach you it in school
- complete garbage
- overpriced
>>54102813
>you have to read the manual
hp50g doesnt come with a manual tho
>>54102765
>>54102813
The problem is that it would cost a lot in for me to import, so I rather buy it on the local craiglist-like site. These are the only good options atm the ti-83 is 57 bucks or the hp 50g for 85.
>>54102884
I think it does?
Either way its online.

Guys, I currently have a Casio fx-991es plus (goes by the name 570es-plus in USA I think),
should I buy a 50g for replacement? Can it replace a Casio e.g can it calculate definite integrals?
Why the fuck would you need a calculator in 2016 other than some shitty 10 bucks device for exams?

>>54098773
What model is that old one?
>tfw bought a casio fx-9750gii for alevel but uni wont let me use it
>>54103936
I'm not sure, I just know it's made by HP.
You could check their product lists to try find it.
>>54103043
I own the small and large versions (dm-41, dm-15L) and it's a nice calculator.
The firmware he cooked up has way more steps / registers than a stock 15c. If you like the 15c you'll love the DM-15L.
Way faster too in case you're waiting all day for your programs to run.
>>54104008
I'll try to find it. I don't think I've ever seen an old wedge-shaped model like that but with an LCD display instead of LED.
>>54104102
unfortunately I've never used a 15c, I don't see why I wouldn't like one though
How is the keyboard? I notice that it isn't like the one on the 15c, but from the video it sounds like the 50g keyboard kind of.

Depends on what you're used to. Are you a new HP calculator user?
>>54104161
>I notice that it isn't like the one on the 15c, but from the video it sounds like the 50g keyboard kind of.
Keyboard is fine, decent but not the same as those 10c series keyboards.
For a dedicated programmer the fact that you can manage your memories over the USB cable is a huge plus for the SwissMicros.

>>54104232
Only started last year, but I started with someone else's 48gx.
I use my own 50g now. Why? Does the 15c have certain quirks?
>>54104261
Well, like I said I would rather not be spending huge amounts for a 15c.
>>54104373
>Does the 15c have certain quirks?
Complex numbers take up 2 stack slots, so you can only work on two at once (if this is your poison).
It lacks a handy UNDO function, but it does have LASTx. This makes undoing a mistaken operation a two-step procedure.
Download and play with an emulator before you decide.
I remember my granddad had a calculator that was nearly the size of a cash register. Wish I knew the model.
>>54104451
You made me realize I'm a pleb with these calculators. I have never made use of an undo function, and I can think of countless times where it would have come in handy.
>>54096935
my university forbids the use of anything more advanced than a casio fx83-es
i gotta say, the new casio calculators have a very good button layout and UI. better than other calculators i've tried

It takes time to get used to them, working out of the manual is a fun way to get the hang of things.

>>54094584
I used to use a TI-92 but these days, if I need to do some complicated math, I use use an interactive python session. Faster and more flexible.
Got a HP 50g today.
Still figuring stuff out, it's not very obvious coming from a TI84.
The CAS is amazing, the solvers, Laplace and Fourier.
The binary/hexadecimal operations are pretty nice too.
>>54107351
Even if you're not used to it, you've got to eventually learn RPN to unlock the full potential of the calculator. RPL is a very nice programming language and you'll find the calculator is completely customizable. (Custom functions, menu, even bind your most used programs to key combos.)
>>54107566
RPN was one of the reasons why I got it.
I've used RPN calculators on my pc and phone before and it seemed much more logical than normal input.
The other (main) reason is that I'm an EE student, so all the symbolic math and linalg comes in handy.
Going from a transfer function to a plot of step response by pressing only a few buttons is awesome.
>>54106583
>no buttons
>shit battery life
>no RPN or RPL

I don't remember the model, any help?
So I got a box today...
Wonder what's inside?
It's a 30b that has undergone an amazing transformation into the ultimate RPN calculator, the WP-34s.
Get one while you still can.
>>54103166
>list price: 850 dollars
why is it so expensive?
>>54107805
>http://www.techedu.com/EL_CADET2.asp
Yeah the Radio Shack set designed by the gentleman scientist Forrest Mims is basically feature-equivalent and is still available used for like $25 for a good one.
>>54107830
>>54107805
I think it might have been even more than that.
This is the closest thing I can find to what it actually might be
http://sine.ni.com/nips/cds/view/p/lang/en/nid/205425
Even if it's just half of that set it's easily a thousand or more.
Really good brand test equipment and prototyping stuff like NI is always stupidly expensive.
No matter what it was a good find.
>>54104327
HP calculators were plotting charts while stored program digital computers were typically interfacing with line printers.

>>54107918
>I think it might have been even more than that.
OK, I looked and that thing is fancy.
Anyone else have one of these?
>>54108069
The HP 9000/300's HP-IL keyboard will interface directly with the HP-41 the HP-71b if they have their HP-IL modules, and there are many plans for simple adapters for other keyboard types.
You could do this in the 1970s.
Also serial keyboards exist for the HP-48 series though I have never seen one myself.
You can have many devices in an HP-IL loop. Pretty neat protocol and it's still in use today as an industrial computing thing.
>>54094693
Which do you like better?
If you have to choose, I'm dropping you off on a deserted island with one of the two calculators and an adequate supply of batteries.
I would go for the 48 myself (actually I would bring a 50g).
>>54094713
>casio normies
Casios are the most normie-grade calculator out there.
Seriously why can't you into RPN like a grownup?
>>54095420
Good show, nice machine.
Pain in the ass though if you want to try to use it as a normal calculator. You should get a WP-34s before they are all gone.
>>54094584
I had 3 of those ones on the left and smashed them all in school
I'm a vegan. I don't use calculators.
>>54094833
Of course not, it's a baby's first calculator.
HP had more impressive *PROGRAMMABLE* calculators 40 years ago.
>>54107666
>Going from a transfer function to a plot of step response by pressing only a few buttons is awesome.
Checked and why do Casio and TI make every different 'mode' separate? It's not easy to use the different facilities of a calculator together unless you're using an HP-48 series.
>>54107351
Here's a little advice for new 50g users. You can use NiMH rechargeables, they work fine but make sure they're the low self discharge type. hpcalc.org has a huge software library, make use of it. I would install HLP49 from there, it's a full online manual for the calculator so if you want to look up a function or see how to do something you can without going into the manual. Also the thing can't use bigger than a 2gb SD card so just get a nice cheapo old one. 2gb would easily store every bit of software written for the 50g series (thousands of programs) so you'll never run out of space. Also learn how to back up the calculator to the SD card, and restore it.
Also if you can wrangle up an inexpensive 82240b printer they're nice to have around. You can print text or graphics with it.
Damn good machine there.
>>54096086
>Does casio even make their own calculators?
Actually Casio and HP both use the same Taiwanese company, Kinpo, for their calculators now. Clearly the Casios are a Kinpo product that HP and Casio both re-brand.
HP struggled with Kinpo, and some quality was lost such as double shot keys, but in some way they are improved as well (gone are the shitty heat stakes for example).
Teaming up with Kinpo gave birth to some horrid calculators from HP though. Take a look at this piece of shit, which actually is a pretty capable machine even though it looks like it needs to go into the trash.
>>54095934
Nice prototyping board, I use a similar model a lot for coursework and hobby stuff. Have it on loan from the engineering department but there isn't a set time I have to return it, they just know I have it.
>>54108260
The only thing that's prevented me from making a wp-34s are the matrices. How are they? When I screwed around with the emulator, you had to type in a matrix descriptor like 12.0203 (2x3 matrix, starting at register 12), and then edit it using MIO or MED. It all felt kinda clunky compared to the 15c
>>54108739
Yeah it's not quite as easy as the 15c but once you get used to it, it's ok. I really prefer the 50g for matrices.

My TI-84 Plus has served me well for well over 6 years now. Only thing I had to do was to clean the battery contacts because Texas Instruments apparently couldn't be arsed to make them gold-plated, and the corrosion caused the calculator to not turn on sometimes.

I would highly recommend getting the printed manual, it might be the best manual made for any calculator, ever, and a couple bucks will go to the authors. They really knocked themselves out with this one, it's an amazing hack on what was just a mediocre business calculator.

Then I read up about them and they have a very dedicated fanbase.
