I have Matlab, Derive, and a good Casio and yet I still want a CAS calculator because they seem to be well made and aesthetic while every other calculator feels disposable.
Anyone know this feel?

Nigger, just get a small laptop with a huge battery.

Also if you could deal with some limitations, you could have a CAS on your calculator IN 1986!
The HP 28C/S had a CAS, and was the hardware and software progenitor of the HP-48 and now HP-50 machines.
>>8002264
>not knowing the TI-92 was running Derive for months on a set of batteries in 1995
That's pretty cool.
I have a question: is there a nice high-quality calculator that is very intuitive that you could recommend?
Not necessarily super advanced, I'd more likely than not just appreciate a calculator that doesn't feel disposable and feels like it's of good quality.

The HP-50g is an amazing machine and it's only $50 from Amazon. They are blowing them out because they have a new meme calculator called the Prime which is a piece of shit like the modern color screen TI's that have battery life measured in days instead of months like the 50g. It comes from the factory working like a normal algebraic-style calc, like a TI, but you can (and should) flip it into RPN mode ASAP.
https://www.youtube.com/watch?v=cPKg_JtI-Ys
It's a nice sold feeling machine, batteries last a long time, it has a real SERIAL PORT and IR, can print text and graphics on an optional (and widely and cheaply available used) wireless battery powered printer (the HP 82242b), it has a full CAS, but it's really neat because you can see up to eight levels of the stack, so playing with numbers and writing short programs is really fun.
Primarily a user would program it in it's built in language, RPL, which is pretty similar to Forth. Defining new functions or 'words' is very easy, and the calculator is designed to be extensible.
It comes with a full HP financial calculator suite (similar to a beefed up 12c clone) and a neato equation and constants library, covering such topics as physics, chemistry (full and extremely detailed periodic table included), geometry, etc. You can go into a constants menu and pop a constant onto the stack, then go find some values from the periodic table and pop them onto the stack as well, then go to the equation library for physics and it'll solve your equations by popping those values off the stack, leaving the result there.
There's really nothing else out there like it, I would get one while you still can.
>>8002373
I might get this soon because I haven't been spending my ridiculous college grant and it's built up to over a 1000 the past few months.
Thanks for the information. I have yet to look at RPN but I will begin to look into it over my next holidays.
Lastly, how do you know so much and why are you so passionate about calculators?
>>8002398
>Lastly, how do you know so much and why are you so passionate about calculators?
I am a Gen Xer and grew up when earlier home computers (IIGS) were on the scene, so having a nice full development environment on a calculator was an amazing idea. I went to a special little pilot school for gifted children where we learned to program in many different languages among other things.
I got the TI-85 when I was 13 and thought it was great until my other buddy pulled out his HP-48 GX.
>serial port
>IR
>much MUCH better programming environment
>much faster
>2 internal expansion card slots
After that I converted but it took me a while to actually get an HP myself. I typically buy them used at thrift stores or whatever, but I did buy the HP-50g, bought another one as a spare when I saw they were down to $50, and the WP-34s new.
http://commerce.hpcalc.org/34s.php
The WP-34s is the most advanced strictly-RPN calculator ever made. It's also very easy to use and program despite the bewildering number of shifted functions.
There is an excellent-quality full printed manual available too. It might be the last calculator in the world that can boast this fact.
I failed to mention that the WP-34s is an open source firmware mod for the HP 20b and 30b calculators and is just great for a classic RPN fan.
The only handheld calculator that implements decimal128. Yes that's right, a 128 bit pocket calculator.
>tfw you fell for the 16 / 32 / 64 bit pocket calculator meme
>>8001733
>shill moar
>>8002425
That's an interesting background. Here in Ireland computers were a bit further off back then so it wasn't an opportunity.
Have you messed about with Matlab and other programming languages at all?
I'm very tempted to buy the WP-34. It looks like the calculator I've been hoping for the past while.
Do you have any more calculators in your collection? Post pictures if you do, I have always had a fascination with older models which were made to higher standards.
Also, what is wrong with the Prime? Is it just a watered down version made sexy with the design and display?
Finally, fuck off mods. I'm sick of good threads disappearing and all the shit ones being up for weeks
>>8002554
>Here in Ireland computers were a bit further off back then so it wasn't an opportunity.
There was an Apple factory in Ireland, I'm surprised that you didn't have those around actually.
>Have you messed about with Matlab and other programming languages at all?
Yes, many, I have had many jobs and programmed in many languages. I own a home license for Mathematica because it's great for a lot of stuff now that it has Wolfram Alpha integration.
>I'm very tempted to buy the WP-34. It looks like the calculator I've been hoping for the past while.
I would get it soon, HP has discontinued the 30b calculator (the hardware platform the WP-34s alternate firmware's hosted on) and the guy is blowing out his last ones. I don't doubt they will be worth $200+ on ebay soon, or even way more like the HP-42s is.
>Do you have any more calculators in your collection? Post pictures if you do, I have always had a fascination with older models which were made to higher standards.
Yes, many many, including some rare non-HP RPN machines. I'm sorry that I can't post too many more right at the moment but if this thread doesn't die by tonight I can.
>Also, what is wrong with the Prime?
It's everything wrong with calcs today. Whizzy color screen, shit battery life, 'educational' focus on little activities built-in, etc. Plus while the Prime has an RPN mode it's kind of separate from the rest of the calc, so it's a huge pain to do stuff that's easy on the 50g. Harder to program for than the RPN / RPL machines by far too.
>Finally, fuck off mods. I'm sick of good threads disappearing and all the shit ones being up for weeks
Yeah what the hell is up with that anyway. There are like 20 homework help questions up, why can't we have a classic science 'n math machine thread?
>>8002198
every math class I've taken from high school into integral calculus, and then linear algebra, allowed me to use a graphing calculator on exams.
I have never, ever abused TI StudyCards to sneak in a crib sheet. Ever.
>>8002554
>I'm very tempted to buy the WP-34.
Gotta add, get the printed manual with it, it'll help you a lot and it's actually fun and funny like the circa 1960s-1980s HP manuals were.

Just download WabbitMU the ti-84 emulator for free on your Android device.
>>8002633
The HP-28 and onward will solve your calculus and linear algebra step by step just like you would do on paper, and you can simply copy each step off the screen if you're into that.
Of course you can tic a flag and turn off step by step mode and have it simplify and / or solve an equation or system ASAP if you don't care about looking at the steps, but it applies the same rules you would with your math training and you can verify this.
It's a lot better anon.
>>8002651
Way to fail to read the whole thread before responding my non-RPN using friend.
>>8002656
hold up; the product picture on Amazon has the HP-50g graphing in 3D. Can it really do that?
>>8002656
I might add that if it encounters a situation where it could try several methods, you can choose which one it will try just like you would with your own math knowledge.
The CAS (caller Erable) is really great like that. It's probably more on the level of Mathematica or Maxima than the TI and Casio / Sharp / etc ones.
Amazing stuff lads and lasses.
>>8002663
Of course anon.
>>8002671
I need to throw my TI-84 in the garbage and find 50 bucks for an HP 50g, yesterday. This is amazing.
>>8002674
Wait until you take your 50g onto the internet.
Or use it to communicate with your car's data bus, or initiate an xmodem transfer or even surf the internet with it.
It's a real computer disguised as a calculator.
>>8002645

>>8001062

>>8002711
Yep.
Here let's look inside the first RPN calculator. Despite it being an antique it could graph, print text, control a plotter, connect to external storage, print and read punch cards...
All in the days when the average mainframe user was doing the same tasks and it was costing 1000000x the money.
>core memory
You could lose power or kick the plug out of the wall and your HP-9100A/B would keep on going without error when power was restored. There was even a reminder to 'check the machine' to make sure it wasn't in the middle of a calculation when you turned it (back) on.
Pretty good for 1968.
TI is legit for babbies though.
