That is phenomenal! My first graphing calculator was the only thing on my Christmas list when I was 14, I still have it, and it is still precious to me. I hope that he enjoys it!

Ding ding ding!

I hope that I remember to take out the batteries before then. That would suck to get the whole place set up and then have a whole corner coated in battery acid due to my own negligence.

It’s one of the reasons that I love collecting them. They all have their unique flavors and quirks!

Another beautiful review! Too bad the pen is such a lemon, because you make it look so nice!

That is a beauty! I have the fx-115W from about the same era, and it is a lovely looking machine. I think that if we’re going off of pure aesthetics, I’d have to put the fx-9750GIII at the top of my list for Casios.

I’ll have to see if there’s a deep dive on that somewhere. It sounds fascinating!

That’s a whole line of pretty calculators there! Is the magnetic reader on the top of the unit?

That’s a great looking machine!

You got written up in The Register! That is amazing, wonderful, and awesome! Congratulations! https://www.theregister.com/2024/09/21/hp_12c_calculator_mystery

My second fountain pen was a Kuratake 13, and I love it! I’ve been using it daily for more than a year and had no problems with it at all. I’ve used it with Diamine Ancient Copper, Robert Oster Deep Purple, and Organics Studio Santiago’s Sea. The only thing to be careful of is that it will get your fingers inky for the first week or so after a refill. The breather holes are above the brush and they seep for the first seven to ten days.

That definitely works for me!

That was a phenomenal write-up of what must have been a fascinating mystery to have discovered! Thank you for sharing it with us!

As an aside, would you mind sharing your list of edge cases? I have a few for scientific calculators but nothing for financials. If one doesn’t already exist, maybe we could even start working on a community document with edge cases and benchmarks?

The first word that comes to mind is “redemption”

I thought it was a beautiful word to stumble upon

That was such a great little calculator! Graphing in the form factor of a large scientific. I loved mine to pieces, but it got lost somewhere along the way. I was a lot less careful back then.

That is a beautiful picture, and it looks like you’re having a lovely time! Plus, I can show my wife that I’m not the only one who brings a calculator on vacation!

Honestly, this is probably the first and last Leuchtturm I’ll buy. The Midori MDs have fewer pages than a lot of other A5 notebooks, but they are also so much cheaper.

Right now I’ve got a Leuchtturm1917 A5 dot grid as my Bullet Journal, a Midori MD A5 graph for my journal journal, a Top Flight A5 dot grid as my Commonplace Book, and a no-name daily planner for my work notes. The Leuchtturm has a few minor issues with ghosting if I’m not careful. The Top Flight isn’t that great for fountain pens, but it was cheap at the grocery store. I only use my fine nibs on it. I do most of my correspondence on either Tomoe River A5 or Clairefontaine A4.

Another one to add to the list of future purchases!
