The 128 bit arithmetic part is really interesting. I wonder whether they used libquadmath and whether they needed to implement any extra funcitons beyond what’s available there.

#12besides slightly different keymap, what are the main differences between this and DM42 (or DM41X)?
They are emulating different HP calculators. The DM42 is a HP-42S clone, while the OP is a HP-32SII.

#13In somewhat related news, HP is releasing reedition of HP-15C this summer.
Thank you for the news! I missed out last time the re-released it.
You can preorder now:

Update: I tried to order and failed. I’ll be watching for a US-based distributor though because I definitely want one.

#14This is interesting; the display can show the whole stack (my daily driver, a 35s has only 2 lines, and the 32SII only has one). Keyboard looks fairly similar to a 32SII in layout; no arrow-keys like the 35s.
Given that it takes only a single battery, I suppose it stores programs in non-volatile memory rather than SRAM (my 35s has two batteries and you need to change them one-at-a-time to not erase the memory).

#15I'm happy one can buy a mighty 4-stack RPN calculator today new. Greedily, I wish they had recreated the 32S instead, as it had a single Gold function key and far less busy silk screening. I say this as a former owner of a 32SII. https://www.hpmuseum.org/32s.jpg
I'm the opposite on this, I like more labeled functions directly reachable with function buttons and less menu scrolling :)
SwissMicros should really do the WP-34s imho:

32S didn't use menu scrolling though.

As far as I can tell, the build quality is the same: fully metallic enclosure with printed keys unlike the double-injection molded ones on the HP originals. The DM41X was released with just one font, one emulating the segmented 'font' of the HP41. This one appears to have improved that by allowing different, easier to read fonts.

#18I hope these people do something similar for the hp48 or 50 series, though I understand it's a big undertaking. I'd be the first person to buy it.

#19Did the Berkeley Graphics (https://berkeleygraphics.com) guy design their website? I mean that in a good way.

#20I keep looking to see if they have the credit card ones back in stock, but they never seem to.
A few weeks ago I added an "rpncalc" command to my CLI "swiss army toothpick" program ( https://github.com/linsomniac/toothpyk ): "pyk rc 86500,24/365x" (x == * == multiply).
On the one hand I love the HP calculators and have leaned on them heavily in the distant past. On the other hand I like having a clean desktop (3d printing some under desk drawers at this moment).
