@moira YESSS! They were my favorites also, especially the 9810 (the one in the middle), which I had previously encountered some 40 years ago, doing some surveying stuff during my military service, in a land far far away. It was obsolete even then, but as an HP calculator fan since my teen years, I was just blown away by this thing.Very nice to see it again.
I wish there was more HP stuff at VCFPNW. Guess I need to bring some of mine next year!

Moravia (the current owner of the HP calculator IP) has announced they'll be making a Collector's Edition of the 16C RPN programmer's calculator next year:
https://youtu.be/vwgQu2s7rxY?t=1185
HP made dozens of scientific and business calculators over the years, but they only ever made one programmer's calculator, so I don't expect this one to stick around for very long.

Free42, the Free Software re-implementation of the classic HP 42s RPN calculator, supports using custom skins, a bit like WinAmp skins but more complex - instead of just a bunch of bitmaps, you get to define the size and location of each button and graphical element.
I have discovered that it its parsing of the layout file is not very strict, so I can wrap some HTML, CSS, and JavaScript around it and get a polyglot file that I can load into Free42 to test, and also load into a browser to visualise the coordinates as I edit them.
(the attached screenshot depicts a skin for Free42's slightly more capable cousin Plus42, but the skin files are interchangeable)

I did a wee bit of 6809 assembly long ago during more comfortable Borland Pascal evolution. Was glad for the exposure and glad to be done with it ;-}
Moved on, with some concurrency I expect, to #HPcalc languages during the heyday; notable for resource discipline.
Organic memory constraints preclude any more current programming; restricted to the standard shell utils, and listening to the birds sing.
Peace and Best Wishes,

I took a chance on a nice-looking HP 19BII on eBay that was listed as untested. It was quite cheap and worst case it’d be a really cool display piece.
I got some N-cell batteries and very carefully installed them.
Nothing happened at first when I hit “ON”. Just as I resigned myself to it being a dud, I heard a beep and the display came to life!
There’s a lot to explore on here and it’s going to be a fantastic companion to my 17BII.

HP1973 project brings the HP-45 back to life, not only with full emulation, but showing the ROM workings under the hood.
Beautiful.

I did some Nonpareil (HP calculator microcode simulator) work, and HP calculator ROM reverse engineering, over the weekend, but it doesn't seem like I got anything significantly accomplished. As usual. Maybe next weekend.

From the 70's, Shanks' SQUFOF algorithm for prime factorising using square forms, with a mention of the HP-65...
"""
...to prove this I had only a hand-held HP-65 with its very small memory (100 steps in the program). Obviously, one cannot put the huge BRIMOR on such a machine. But one can put on the simple algorithm...
... factor the 19-digit N₀ as
(22) N₀ = 139001459 · 8294312261
even though the HP-65 only computes with 10-digit numbers.

I was about to say, surely you can't object to the HP-16C!
The first HP calculator I bought was the limited edition 15C - I seem to have picked up some more since then.
There are lots of in-browser emulators, some of which function as webapps - see
