Migrated to @luana@wetdry.world 🏳️‍🌈🎃🇧🇷Luana🇧🇷🎃🏳️‍🌈Anyone here got a CASIO CP-400 or CP-400+E (ClassPad II)? Or CG-500 too, since that’s just the same calculator on a different enclosure.It’d be really helpful if y’all could submit your calculators Serial Numbers to my.calcs.quest! As well as do the <a href="https://bible.planet-casio.com/teamfx/keypress_cp.txt" rel="nofollow noopener" target="_blank">Diagnostic1 key combo</a> to figure out your ABS_Date (maybe add at ‘comments’?)Specially if it was bought late 2022 or later (but older models, submit too!): Apparently there’s a new revision for the ClassPad (possibly for the cg500 too? haven’t seen that) that breaks compatibility with OSes older than 2.01.7, and hollyhock runs on 2.01.2. We’re trying to figure out what changes and how the SN works at Hollyhock-2 discord. We know that affected calculators have an ABS_Date of 2022, while afaik all previous ones had an ABS_Date of 2012.I have a CG500 bought in mid-2022, but it (thankfully) has the 2012 ABS_Date.<a href="https://tech.lgbt/tags/CASIO" class="mention hashtag" rel="nofollow noopener" target="_blank">#CASIO</a> <a href="https://tech.lgbt/tags/ClassPad" class="mention hashtag" rel="nofollow noopener" target="_blank">#ClassPad</a> <a href="https://tech.lgbt/tags/ClassPadII" class="mention hashtag" rel="nofollow noopener" target="_blank">#ClassPadII</a> <a href="https://tech.lgbt/tags/fx" class="mention hashtag" rel="nofollow noopener" target="_blank">#fx</a>-CG500 <a href="https://tech.lgbt/tags/fx" class="mention hashtag" rel="nofollow noopener" target="_blank">#fx</a>-CP400 <a href="https://tech.lgbt/tags/Calculators" class="mention hashtag" rel="nofollow noopener" target="_blank">#Calculators</a> <a href="https://tech.lgbt/tags/Homebrew" class="mention hashtag" rel="nofollow noopener" target="_blank">#Homebrew</a> <a href="https://tech.lgbt/tags/OpenSource" class="mention hashtag" rel="nofollow noopener" target="_blank">#OpenSource</a> <a href="https://tech.lgbt/tags/Hollyhock" class="mention hashtag" rel="nofollow noopener" target="_blank">#Hollyhock</a>

cthululemonThis little mechanical calculator is one of my favorite objects. It came to me with what turned out to be a fouled 10s pin retaining ring; it was a bear to take apart, ‘machine’ a new part, and reassemble. But it works!

Boris KretzingerWent to the Hessenpark today, which is basically an open air museum with several old half-timbered houses. In one of them, I stumbled upon an exhibition about the history of the transistor. And there were some calculators on display as well, two made by Commodore. The one of the right is one I did not see in real life so far - nice surprise 😎 <a href="https://oldbytes.space/tags/commodore" class="mention hashtag" rel="nofollow noopener" target="_blank">#commodore</a> <a href="https://oldbytes.space/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://oldbytes.space/tags/calculators" class="mention hashtag" rel="nofollow noopener" target="_blank">#calculators</a>

Stefan Wolfrum :mastodon:<a href="https://hachyderm.io/@theotherlinh" class="u-url mention" rel="nofollow noopener" target="_blank">@theotherlinh</a> Very nice! The HP 35s is a bit of a look-after machine because it was quite popular when HP still sold it. Unfortunately, they stopped that not very long ago (I think last year?) and people started to grab the last available items while supplies lasted. I bought one several years ago and still love it! I’m a bit of a <a href="https://mastodon.social/tags/calculators" class="mention hashtag" rel="nofollow noopener" target="_blank">#calculators</a> collector (mostly HP but some TIs, Casios, Sharps as well) so I always appreciate these lovely little machines! 😊 Got an HP200LX, too.

Faster CPU, and IEEE floating point, which would be nice to have consistent with desktop.It has Multiball! > Another way to represent Multi-State is to consider each open State like a virtual calculator in the background; activating one State is like bringing the corresponding calculator to the foreground. <<a href="https://appdot.net/tags/calculators" class="mention hashtag" rel="nofollow noopener" target="_blank">#calculators</a>
