Ah, it's now obligatory!
I'd say it's kind of nice. Something very pleasing about having the two lines, but it is not more functional as a result. The constants/conversions are very nice and well-implemented. Think some people will find them useful for day to day stuff or at school.
DM-15L official 2-line firmware has landed
The official Swissmicros 2-line firmware dropped on the Winter Solstice as an early Christmas present. It also has a nice set of constants and conversions.
Oh wow, the whole thread is just people suggesting alternatives!! OP - enjoy your neovim and don't listen to the rest. It's a terrific editor and will be around for many decades more.
That thing holds it's place in computing history. Kinda the first pocket computer?
He really likes it. The titanium back has given a great looking engraving of his initials. Now just hoping he didn't lose it!
Got a DM-15L for my son, and hand printed/bound the manual
I'd been toying with the idea of what RPN calculator a kid could use at school here in the UK. I thought the sticking point would be that most RPNs are programmable, but turns out that isn't an explicit exclusion on the JCQ calculator guidance for GCSE and A-level exams. They can also use graphic calculators. There is a hard no on CAS. The HP-15c seemed the least likely to cause issues with invigilators, so went for this. We'll have to see if it works out though.
Respect for the 4 level stack!
Very nice! Was this a rebranding of another make or made by radioshack themselves?
Ah yes that's a pretty nice graphing calculator, also looks pretty good in pink!
I think this is the best looking Casio (fx-992s)
HP-65 and friends
The HP-65 was not only HP's first programmable scientific, but it could also read and write magnetic cards. There were several 'pac's of cards allowing it to tackle financial, astronomical, aviation, electrical and other speciality field calculations. The buttons were double shot and have a lovely tactile click. The red LED screen is remarkably crisp and easy to read.
I think I like the buttons and the highly-specialised functionality. At least that's what I think when people say 'what's the point, you have a far more powerful calculator in your pocket already'. Yes, one without buttons.
It is! Not mine sadly, but amazing to see such a thing. I didn't have much time so apologies for not stopping down enough - I didn't realise at the time!
Forensic Financial Tests
These are the tests which can give you quite a good profile and accuracy rating for your financial calculator. Any more contributions and confirmation are very much appreciated and I will update the swissmicros page (though I may need to move it off there at some point).

Really glad you enjoyed it!! It's a very very small niche of people I think.
Totally would love to work on an edge cases database! It is no secret (posted on swiss micros forum), but I can do a submission here if that works?
It's actually a really nice bit of software. Really nice range of functions.
Yes, looks like coated aluminium - not unlike a can but a little thicker and with no sharp edges. I've not seen these before but I think they are disposable/recyclable - i.e. a replacement for a plastic cup and far more pleasant to drink from. I took mine home as a souvenir, but I have had to unsquish it today taking it out of hold luggage.
Yes, in fact before I got my DM42 I had one holiday where we had no internet access in the evenings and as the children were small and slept early, I didn't have much to do but I was able to learn a lot about using and programming free42.
You do have to remind yourself at the beginning that you're using RPN, but after a while it feels a bit like working sums out on paper.
Sea, beer and a calculator.
A random shot of my calculator 5000 miles from home while I enjoy a beer near the Pacific. We had been discussing how much water was on earth and what size of a ball it would make. I have no affiliation with the brewing company so apologies for the product placement.
Just to clarify - means two taps of the esc key in succession will clear highlighting (ps I'm curious how other people do it!).
nmap <esc><esc> :noh<return>
Yes, I also have caps mapped to esc, but done in keyboard firmware so that holding it functions as ctrl.
In neovim I have two escapes mapped to :noh
I tried to play this on an original IBM PC. Without a mouse and only 4 colours. It went badly.
Yeah, I think they need to tune their nibs before they let them out. No such thing as too much flow - just too little paper.
HP-12c Platinum
HP's most accurate financial calculator, oddly enough, and despite only returning the ceiling of solve-for-n.

First post on Lemmy, and i see you like pens too :)
