Couldn't afford it then, now I just have a collections of HP-35, HP 35s, desk top HP-46 and other HP versions including some with magnetic card readers.

I have one, now in my hands. Inside it there are some programs I wrote to calculate areas of lands where I surveid. Azimut, angle, with Gauss method. I chenged batteries to not loose these programs: nostalgic mood...

Can we display the results as a fraction or exact value rather than as an approximate value? I mean 25/75 = 0.333333333... but it's also 1/3 and I would prefer this result as a fraction.

I hate free42 and pcalc lite because you have to pay to actually see your stack it’s actually infuriating

Can u tell me how to increase it's brightness?

991EX was the best calculator ever made by Casio and they mess it up with the 991CW. What were they thinking? In an exam situation speed is of the essence and if you have to dive into layers of menus to get to a function its a non starter.

When you mentioned that Swissmicros provides state files for all the programs in the original User's Manual as well as the HP-32S Engineering guide, I need to ask if the state files are already designed into the DM32 or if they are available for download someplace. If they need to be downloaded what URL are they found at?

Thanks for the video. If only I could hear what you're saying.

So I have watched the review videos, but im still confused which one is better: The Ti Nspire or the HpPrime? It seems like the Hp Prime is easier to use with the touch screen. If I were to buy one for an engineering class which one would work better?

All the years I did those algebraic equations on paper and your telling me there are calculators that just give you the answer if you enter the numbers... 💀

Back in 1990, in Wollongong Australia my HP15C had a faulty key. I loved the thing. I took it to a HP service centre and they couldn't fix it. I had changed careers at the time and said an emotional goodbye to my trusty old friend, my HP15C - The HP service centre kept it. Now I have my 15C as an app on my iPhone.

I want to buy a calculator that is excellent but I think the claspad is already very old although it is still exceptional, which one would you recommend? I have no price limit and I like good experiences for the end user. In this case, I am between the Texas Instrument TI-NSpire CX ii cas, the HP Prime V2 and the Casio Classpad 2. Greetings from Mexico.

Esta fue a mi entender, la mejor calculadora de casio que tuve, me gustaba mucho el lenguaje simple para programar, lo que me parecía muy poco era la memoria ram, esa calculadora con al menos 24k o 16k hubiera sido insuperable, pero claro, estaban las graficadoras que tenían más memoria y eso era otra cosa.

Cuando era chico a los 10 años aprendía a programar con esa calculadora , año 1978.... cuantos recuerdos, pensar que en esa época 127 pasos de programa no parecían ser pocos. mi viejo todavía la debe tener. me llamaba la atención términos como salto condicional, salto incondicional, subrutinas, todo un mundo nuevo para mí.

Please do the HP 28SX, my first love.

As always, this is a great video. Thanks so much!

HP 48sx was the chemist calculator! This was the calculator of the early 90's. The Achilles heel is after 25+ years. It has the same issue like many HP calculators, the ribbon starts to fail. another failure is the way it's put together, very hard to take apart, very unfortunate. And with all these faults, it is probably one of the most enduring calculators and probably the last great HP calculator that was made. For anything that HP does today, it's nothing compared to what it was before..

If you flash the 42 with the 47, can you bring back the 42?

It is too bad that they didn't add more functions like normal distribution features, I know it can be programed, but would have been nice if it was built in.

It’s one of my favorite calculators. I really enjoyed the fact that no one dared to borrow it because of the RPL input. This introduced me to programming and algorithms.

An ex-girlfriend used to have a 12C Prestige (full gold, like the prestige silver style), but someone at her university liked it very much and silently took it away... And I still have my Prestige silver, first version with no ( and ), but they keyboard is failling pretty bad, unfortunately.

Thank you for the great demonstration and brief history of dc. I especially like your demo of macros. I'm a dc fan for sure. I use dc for quick calculations oftenly. I also use dc scripts for tax itemization. It's easy to double check the script against other records. As you demonstrate, using text in dc for interaction can be done but with some friction. dc also accepts stdout so you can pipe a heredoc to it, letting you use shell variables in a dc script.

1988, this was my first programmable calc, i programmed a silly game in hp's assembly-like language (like the jumping dinosaur game in chrome mobile, but with a stick-figure) - only issue is that there was no command to just read the keyboard without stopping processing, so i had to constantly press "space" to advance to the next frames , and another key to jump the obstacles.

What makes the C47 better or different than the DM42? What is so cool about it?

Esta en inglés en español por favor

Hi! It's missing the HP12C Prestige! Anyway, it is just a disguised 2nd. series Platinum, with a hard-to-read (f)-shifted function set (the brass-collored background of the keyboard faceplate was not well chosen, though...)

Basically, its a calculator made for newcomers. with emphasis on convenience and menus over speed. So even though I REALLY need that pink calc, I don't think I'm gonna get it.

Do you think the C47 will work on the DM32 hw?

Hello. Thanks a lot. My fx-5000f works fine!

Circa September 2024, I'm thinking about the new Swiss Micros DM-32 ($300) and HP-15C Collectors Edition ($150). But those are both much more expensive than a used HP-11C off eBay, which I just snagged for $60. As a "basic scientific RPN" calculator it's hard to argue against that price. It's a pity they (HP) dropped the HP-35S (now $275 used! on eBay), as it was a great "basic scientific RPN" calculator for my high-school-aged kids. But who am I kidding, I bought this HP-11C for myself, as a shelf-queen, just to round out the collection of HP-12C, DM-15L and HP-16C. Now the quest is on to find that HP-10C at a reasonable price.

Please make a video about hp 41c

some guys do the test to calculate the sumation that this old sci-calculator range no.2, lose to HP Prime, You shall show the degree-minute-second function during the video... Actually, we would like to see this old advanced calculator can be imported or export to the PC and other universial interface for the data log that would be great!

The only addition I would love to have with my HP15C would be bluetooth etc. access to it so that I could save and load programs from/to a laptop.

880P vs this one.. wich one you recomend?

it has some kind of port on the top...?

Does anyone know why the fraction display function glitches so badly? If I enter 5/8 (0.5.8) I get the correct decimal value of 0.625. If I change to fractional display, I get a wrong fractional value of 3/5 (0.6). In fact, all of the fractional display values are wrong if you try adding up fractions. If HP wants to simply fractions it has to be per the fractional measurement system (ie: 1/2, 1/4, 1/8 1/16, 1/32 ...). Nobody cares how many 1/5th of an inch anything is because that is not how the fractional system works.

Build quality of the second edition of TI Nspire CAS is inferior to the first edition. The color side in particular is a very low quality plastic.

There is plenty of information out there about TI’s lobbying to make their calculators mandatory in math courses and standardized tests. When I was going through tech school in the Air Force, we had to use a TI-30. Overall, it did what it was supposed to do. But later, as a more seasoned adult, when I saw TI calculators showing up in textbooks, I instantly thought, “Hey, wait a minute. TI is doing some slimy stuff here.” They basically made it mandatory for kids to buy their products even if there were better alternatives available.

Buying a 12C to use in algebraic mode is a bit like buying a sledgehammer to hang a picture on a wall

In 80ś and 90ś I owned an HP33E and a HP41CV and loved them, but since i got the HP49G i had never owned an HP calculator, the 49G was so bad i could not believe it. Tried to use despite the spontaneous cracks in its body, slooowww working, batteries eater, and bad display until the keyboard broke tottaly after less than one year of light use. Since them only casio calculators.

Any suggestions for a factional scientific or "pretty print" calculator that you can scroll back and select calculation history to insert into the current calculation? My TI89 really spoiled me in this regard!

Is this the HP prime that people keeping bragging about on comment sections of Casio products reviews???

You need better buttons.

What's it like actually using the calculator and pressing the buttons compared to the original? Is it any good as an actual calculator for regular usage? Or moreso as an oddity to play with every so often

Imagine someone borrowing this calculator for an exam 😂. I can only imagine the horror of them trying change to decimal or even find the factorial function.

Best of all, SwissMicros has good customer support...

The screen is far better than the one from the Casio fx-7500.
