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?

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.

I was a freshman at Georgia Tech in Atlanta, GA studying engineering in 1972 when the HP-35 came out and a year later when the HP-45 came out. The HP-35 cost $350 and my tuition for one quarter 3 months was a little over $400! It was a HUGE amount of money but the ENVY of everyone! We all had K&E slide rules. $350 in 1972 is equivalent in purchasing power to about $2,630.65 today, an increase of $2,280.65 over 52 years! Unreal, makes me feel old (will be 70 years old in a week!).

Which of the three would you recommend for TVM, uneven cashflow and other financial calculations?

I spoke with the folks who now have the HP license (team that released the HP-15 Collectors Edition), and they say they are planning on a re-release of the HP-35S in the next 24 months. Figured I would relay the news.

In the words of Han Solo "And I though RPN was hard to use"

My first personal computer was the TI SR-56 in 1977. Great fun! My favorite calculator app for Android is RCL-58, a fine emulator of the 58C.

I have one (bought myself around 1989) as well. Must be around 1995 on a usa trip, I found its twin a "Radio Shaek CAT.NO.65-993 MODEL NO.EC-4026" for cheap (10$?). The RS has a bit different color scheme, but still black/grey. Both work fine till today, though not sure when I used them the last time, besides now powering it up and checking that the battery is still alive ;-) I find their design has aged very well. It still looks great and modern to me and not like 35 years old. ;-) (I just googled to see what images would show up searching for 1989 (in that order): Taylor Swift and Tiananmen Square, ...)

God bless the guy who create the emulator for Android phones. A great opportunity for many people.

Greetings. Where can I find and buy this calculator, im located in bogotá colombia? i never seen a calculator like this before! I usually used the FX 880P.

I had this exact model going through college. Great device.

i got a radio shack ec 4020, which is a rebranded 4000p. such a cool calculaor, cant wait to try some programs with it.

A Russian colleague gave my an MK-61 that he kindly organised for me in his hometown. What a fantastic device ! I really love it. And guess what: it still works. There is an MK-61 emulator for Windows available, called `Calculators 3000` by Eugene Troitskiy, and an excellent English translation of the original manual is also around. You may give it a try.

Still got this fantastic calculator from 1982 with the FA-2, still the best from Casio

I lost my mind or this, Prof. Brain Cox !!

How does this new one stack up against the 42s? Do you have a video comparing the two?

Pretty shameless that they just rerelease the same calculator from 2011 (only with slightly higher clock speed) in 2019. Nowadays, even $50 phones are 10 times as powerful, there are countless free calculator apps, and you can even connect an USB keyboard, so who'd still buy such a calculator?

Can anyone post links to any web sites where I can download apps for this calculator? I am most interested in chemistry.
