@Romero Regarding Droid48, the developer has dropped support for it. Consider switching to Emu48 For Android, which also has more features. If you stick with Droid48 and want to get data/programs _out_ of Droid48 to save or share, you can install my own companion app called "Droid48 Reader". However, because Droid48 support has been dropped, my own app received what will probably be its last update last year.

This is a really remarkable jewel of one of the greatest companies ever founded. Back in those times, they were still named „Hewlett Packard“ in full. I am still loving my HPCV/HP41CV. Today using a Swissmircos DM41X too🎉 Thank you very much for every hour you all spent on the HP41.

I studied the entire HP 48 SX calculator manual during 12th grade in 1992, as it was my first real calculator given to me as a gift by my father. I learned to use the calculator very well over the years in college, but many of the things in this video would have made my usage much more efficient. I still have the SX and GX with a bunch of expandable storage cards, and even the printer. It was the coolest calculator ever made and probably still is in many respects. I also have the entire line of HP 95 lx,100lx, and 200lx micro computers.

In my college we had an HP ambassador to give us course for intermediate and advance use of the calculators, 48 series, with a device that was an LCD screen for the overhead projector connected with the serial cable to his calculator, so we could see his screen. yes, best calculator ever, I tried the 49 & 50 series, just not the same, yes they were faster but the buttons were horrible. but now with smartphones we can even use Wolfram in the web and calculate on their clusters, it is expensive but we can get a ton of power on our modern "palmtops" or "handhelds"

I managed to buy one of those overhead project displays for the HP48. It actually connects via one of the card slots, surprisingly.

I got my 48sx in 1990 for college; had a detour and 30 years later I'm back in school for EE to finish what I started. The 48sx is in class with me. Pretty sure it's older than most of the people I'm in class with these days. It's a little old and slow, and creaks a lot, but still gets the job done (just like me) :-) Still love it and wouldn't trade it for anything.

I wish you the best of luck @ your back to college journey… planning doing same thing next year at exact 30 years later also, back in 1994… I still have my HP48GX & HP49G up & running😅

I loved my HP-48SX. I got it for college in 1991. I wish I had access to this video back then to get more juice out of it.

One of the greatest handheld calculators ever. And by the way, the keyboard-layout is the best ever.

Thank you for making this video available. I had a 48sx in the ‘90s and used it a lot in my eng studies. We had the same model with a class mate. We developed and exchanged programs via IR. It was incredibly useful that time. Unfortunatlely the buttons dont work on it anymore. However a very nice iphone app called iHP48 has recently been released so I can enjoy again the good old hp48 experience. I came here to relearn the basics of programming.

Long live RPN! By now I am literally befuddled when faced with a non-RPN, non-stack calculator. The head of the engineering program at the Community College I attended made us buy 48's for Statics in 2002. They were about $120 in the college bookstore by then if I'm remembering correctly. Still using the 48GX I bought then, every day at work, and it is perfect! I don't do high level math on it anymore, but I can't believe my colleagues who use the Windows calculator instead of a handheld calculator. I made my own interface cable and managed to push one pin into the calculator body. I called HP customer support and they offered to send me a replacement! That impressed the heck out of me, and made me a loyal customer for as long as HP makes calculators. I just ordered my son a Prime G2; way overkill for high school, but should see him through college and beyond in a technical field. The replacement 48GX HP sent me sits at my computer desk at home.

29 years later, the 48G is still the best calculator I have ever owned. By a wide margin.

I have found this video wildly useful for understanding my 48g and 50g. For years I just could not grok the paradigm of how to use these things. And the 48g manual is like reading the IRS tax code translated into Latin. But now I keep the 50g handy after watching most of this a few times.

I really liked the HP 48 SX. It's orange/blue keys and the Swap key were great! Early models had mechanical problems with the keypad. HP apologized and offered me their new 48GX at a preferential price. Which I assumed. But the purple/light blue color choice at GX was never mine. The 48SX key colors were epic. - Nice to hear that there are later 48SX models with a durable keyboard. :-)

Bought a second hand HP-48GX on the strength of this video. No regrets.

I think someone should create an HP48/49Emulator for Prime similar to Emu48 for Android. This video was nostalgic to view. For years I've found it relaxing to sit down with an HP48, hp49g+ or HP50g and create programs and libraries. I also like relaxing with an Android often using HP emulators.

Thanks a lot for uploading this video! Amazing calculator! I have the HP-48G as hardware and the Emu48 program in my Android phone. This video was made with the 48SX and it is difficult to follow if you have the 48G (different menus and options available). Fortunately, I can configure the Emu48 program to work exactly as the 48SX and follow the video!!!

love this video, thanks!!!!! hp48g ... the best!

BOUGHT THIS IN 1993. this calculator was amazing. NOTHING came close to it. RPN is the best way to use a calculator.

that video brings back old memories, i had a 48GX when studying engineering, a great calculator, I still have it and still wokrs after nearly 30 years

Bought mine in 1991 and still using it today...the HP50 is $500!

Great video

As a calculator, it is absolutely unbeatable. But it has/had some serious design flaws. For example, a very large number have been affected by contact errors, which cause buttons and the screen to stop working. I've had four of them and all of them have had contact failures. The glued-on metal plate has a tendency both to loosen and to become dented. Sticking on a metal plate of very soft/flexible metal, was a really bad idea. The calculator is assembled in a way that makes it completely impossible to open. Given all the contact errors it tends to suffer from, it would have been nice if it could be opened. But as I said, as a pure calculator it is completely unbeatable - as long as it works, that is.

ok i want to buy one of these now

Cuando era estudiante de ingenieria, esta calculadora HP48G era lo maximo frente a los modelos de CASIO, resolvia todo, acompañado de un menu respetable de opciones que la HP PRIME no tiene a pesar de los años y que Hewlett Packard debio lanzar un producto realmente PRIME. la HP48G solo contaba con 32KB de memoria y la HP48GX podia ampliarse con una tarjeta hasta 128KB de memoria. Increible que con ese poco espacio se podian hacer maravillas de programacion en ingeniera quimica (mi profesion), calculos iterativos mediante programacion RPN que incluso podrias graficar automaticamente y darte los resultados que querias. Me emociono hasta las lagrimas por mi calculadora HP48G que me costo 100 USD pero valio la pena el gasto, pues en esa epoca no tenia dinero. Aun la conservo pero ya su pantalla esta fallando y busco cambiar su pantalla y eso ya no encuentro. Igual seguira conmigo hasta el final. Saludos desde Lima - Peru, January 2022

This calculator came so tragically close to being the perfect marriage of RPN and Algebraic. All they needed to do was make the equation editor the default command line and make the ENTER key do what the EVAL key did. You could type a number followed by ENTER and it would push the number onto the stack as usual for RPN, or you could type an expression followed by ENTER and it would evaluate the expression and push the answer onto the stack as usual for algebraic but with automatic memory function. The multi-line stack display actually made RPN usable by mortals since you no longer had to keep the stack layout in your head as with the earlier single-line displays. The units system is a thing of beauty and I cannot understand why spreadsheets do not implement something similar today. Sadly, after this apex of the calculator story HP did RPN/Algebraic as a modal choice rather than something you could mix-and-match before dropping RPN altogether shortly before calculators finally died. It is worth checking out one of the emulators, and downloading the full user guide. These days you do not even have to pay extra for the top of the range GX!
