@bondo Have you heard of the brand new and actually by HP made (well, somehow) 15C Collector‘s Edition? It‘s available for sale and I have one (bottom one on the photo) and love it! It has a hidden 16C mode, too! 😉 👉 hpcalcs.com/product/hp-15c-col I, too, have the programming cable so I can flash it with fixed firmwares … 😉

@metawops Such wonderful machines! I still regularly use my HP-11C, 12C and 16C. These on the photos were all bought and used by me over long a period of time (except one of the 67s, which was my father’s) : mastodon.social/@bondo/1115164

@dm319 You‘re very welcome. 😊 Last time I joined the virtual meetup was because they had Bill Wickes as a guest and he talked a lot about his career at HP and the development of HP calcs – most fascinating! 🤩❤️

@SarahKL REALLY VERY cool, Sarah! Love your emulator a LOT! 💜 I own several old HP calcs, the 35, 45, 55, 67 are amongst them. Being able to „watch them work“ is nerdy awesome!! 🤓😎🤩👍👍

@ericsfraga @tacosandlinux HP-41C - brings back memories. I had one in the late 1980s when I started studying engineering. The programming part always felt a bit clumsy though (tiny display). So I sold it and shelled out a couple of bucks on top, and spent a fortune (for my standards at the time anyway) on a 48SX in the early 1990s. The greatness of #HpCalculators lives on in #EmacsCalc !
