hello group, sometimes when I see the new color and touch calculators I wonder if you can still be proud with one of these 2 excellent calculators if you see it in a practical way, given the advancement of the new models

Great calculators, both of them.

Try and install on your phone the EMU48 application, that replicates the HP48-50g (& other models), but run 100 x faster than the physical, original calculators.

Greetings,
If you are into surveying software, I would recommend Jacob Wall's excellent program Cogo+ Pro. Recently I was looking for updates and noticed that is free of charge now, some years ago it was something like $275 USD. A 50G cannot run a survey instrument, however with Cogo+ Pro you can do comps that you used to do on a TDS48 but you are able save your points as ASCII or DXF or KML or Lat/Long files, store them on a 1 or 2 GB Secure Digital card that the 50G accepts, pull out said SD card and transfer back and forth with a computer. If you do coordinate comps and have a 50G...why not?
check out Simple Geospatial Solutions at https://sgss.ca/index.html and scroll down to 50G software. If you want his software for the HP Prime, that you pay for.

HP 45, HP 67, HP 41's C, CV & CX, HP 42s, HP48SX, HP48GX, HP 50G, HP Prime, I am a big fan of Thomas Okken's Free42 loaded on a smartphone & then punching in my old 42 survey software from the late 80's and early 90's. Much of which is available on hpcalc.org (RIP Ted & Thanks still!) Being able to do things like grade intersections quickly on your phone can be handy.

One of the machines in my regular "daily driver" rotation is a 48g.

Even though I now use less than 10% of its overall functionality, it's still a joy to use, for its multi-level display and unlimited stack. I have an interval arithmetic library I wrote for it: not perfect, but still very good for when I am doing calculations with lopsided uncertainties or different ones in different steps.

The built-in date/time math is also easier to use than on some of my other models, so it's my go-to calculator for that as well.

I've never tried carrying around a calculator this large, but mostly I am near a desk at most times now, and can easily just reach for it if I need it.

So, yeah, 48gx or 50g+, still a good investment!

Daily drivers: 15c, 32sII, 35s, 41cx, 48g, WP 34s/31s. Favorite: 16c.
Latest: 15ce, 48s, 50g. Gateway drug: 28s found in yard sale ~2009.

It really depends on your perspective. I like my calculators just as much, and besides, I don't get to enjoy handing my computer to people and counting to 10 before they say "Hey, there's no EQUALS button on this.."

Last time I experienced this was in senior high school but I still cherish the memory of having a "lend-proof" calculator.

Emu48 has been my "calculator" for casual use for a while now. Having grown up on 28/48/50 lineage, I love being able to use 48g key layout with real speed.

I am using Em48 regularly. The HP50g version has enough big integer stuff that I can do reasonably serious number theory. It's much easier to program the Pari. My only problem is getting really large integers out to text. I have been kludging it by displaying the integers in 15-digit chunks (or so) and using a screen capture that's on the phone.

You should be able to use the Copy Stack feature to copy the large integer in one big chunk.

Edit: Seems that Copy Stack can only copy up to 127 characters. I wonder if that is a bug or just a limitation. Still, copying 127 digits at a time is better than 15.

If you convert it to a string before copying, you should be able to get everything in one step.

Example (exact mode, of course):

999 FACT
→STR
<Copy Stack from EMU48's Edit menu>

Pasting into a text editor of your choice should result in the entire string of 2565 digits.

If you work with numerical matrix / eigenvalues / vectors etc then it is an excellent and quick calculator with some extra software. Especially if you install hpgcc3 and libraries with software programmed in C.

Thanks. It looks like this will work.
