@drj @bondo Awesome! Good to see the Applications book there, too: managed to find a cheap one of those last year.

@drj @bondo "sweet brushed bezels" I can only hear this in the voice of Ron Burgundy.

@bondo @drj Always looking out for a 16C at a good price, but never finding one. Here's my HP-45, though.

@drj "Notation Reversal", a Netflix limited series, coming Fall 2025

The calculator i use the most for actual calculations is an emulated HP-45 that is written in Python and that emulates the original ROM. It's HP-1973 by @SarahKL and I think it, and by extension she, is incredibly badass.

@drj Going to put this as a pull-quote on the big-box release when Microsoft/Apple/Google pay me £££ for HP-1973 on 3.5" floppy.

Happy Multi-Layer-Virtual-Reality End-Point Day to everyone who celebrates: "The Thirteenth Floor" (1999)

@w5pny @JoeRess @degville Hmmm. The keybindings are defined in hp1973_prefs_[OS].json. In theory they should work for the numpad but a quick google is telling me that tkinter and numpad keys don't play well together. Unfortunately, I don't have a keyboard with a numpad, either, so I can't do any testing.

@dm319 Yeah, 4-bit binary coded decimal in the registers. It's get harder and harder to get old HPs for anything affordable. (Although the Facebook group seems full of US folk finding them for 99¢ in estate sales.)

@dm319 They are! You can see their brilliance and their clear love for what they were doing in the hardware and software. There's a page on the web specifically about the HPs and Cordic: googling should turn it up. Good luck with the '67 bid!

@dm319 It's running the original ROM code, and that uses Cordic, so by using stepping mode and following the code/memory contents, yes, that should be possible, if a little tricky.

Here's @JoeRess, @degville and the team at @LateNightLinux saying nic(h)e things about HP-1973 (which you can get at https://sarahkmarr.com/retrohp1973.html): https://www.youtube.com/watch?v=KqWmGXCIvW4&t=467s

@pellitory@mastodon.ie Oh, thanks for letting me know! Loved hearing them talk about it and "grudgingly admitting" that it was pretty cool. 😀

@metawops Thanks! "nerdy awesome" is the perfect phrase!

@l05tchild I like macOS because it's so like linux 'under the hood', and I was used to that. But I think moving in the other direction, macOS to linux, is trickier: macOS is very polished and easy to use. Linux has come a long way since my 1997 Redhat install, but it's still challenging at times, particularly when something doesn't work. If your partner is tech-savvy, it maybe fine, but in terms of a "just useful and nice to use" computer, not so sure.

@netspooky Thank you so, so much. (If you'd like a version which runs directly in an actual terminal session, rather than 'cheating a bit' by running in its own window, you can grab HP45TERM from my website.)

@eduqate I do love the 16C: it's a model I could see myself using a lot. I have PCalc on my iPhone, which covers scientific and computer science, and all in lovely RPN. I do have an HP-35 and HP-45 (and would have more but for prohibitive prices).

@mvilain That's very kind of you. I don't. I might set it up for other (maybe photographic) projects. The kind words over the past days have made this project worthwhile. Well, I did it for myself so it was always worthwhile, but it's certainly been spirit-lifting knowing other people like it.

@mvilain I used Casio, TI and HP through school/university. Bought a pristine HP-45 a couple of years ago.
