I'm definitely not saying that they are stupid machines, just that I'm too stupid to use them
It is a beauty, but it's sure seen better days. It kept displaying Low Voltage, even with fresh batteries. I cracked the case in a few places taking it apart to fix it. I have no idea what I did, other than touch a multimeter to a few spots on the board, but it works fine now. Dumb luck, I guess.
It is absolutely gorgeous, but I've always been confused by financial calculators. The buttons are all gibberish, and I have no idea what they do. I've got a TI-BA II Plus in my collection, but I think I've only turned it on four or five times 'cause I get scared.
Between the PDAs and my bullet journal, I'm pretty well set.
I've picked up seven Asvine pens over the last year, and have been very happy with all of them. They're an impressive pen maker.
Gorgeous photo of a couple of beautiful machines! The DM42 is on my bucket list, but my wife needs some serious convincing that $250 USD is OK to spend on a calculator. ~~What pen is that, by the way?~~ Nevermind! I looked at the alt text!
Thank you! I am so excited, but terribly nervous, too!
My first fountain pen was a Lamy Safari Charcoal with a Medium nib. I still make sure that I write at least a couple of lines with it every day. It's currently inked up with Diamine Midnight.
It's a fun way to combine a couple of different collections. I'll need to throw up some more pics now that the community is getting to be more active!
Not too terribly much. I'm a network devops engineer, so a lot of my day is just parsing JSON. Stuff pops up from time to time, though, and I'm grateful to have my collection. I'm also going back to school at the age of 48 for a BS in Physics, so I'll be putting them through their paces over the next few years, too!
That machine is in great shape! I had a Casio fx-7700G in high school and always felt like I had one hand tied behind my back when I had to use a TI-82 for tests. They were capable little machines, but I didn't have the muscle memory to use them quickly.
The TI-86? It's actually a beast of a calculator when it comes to Linear Algebra. It handles complex matricies better than any other TI calculator with the exception of the Nspire CX and CX II. That said, I have never used one either, lending credence to your observation. I have passed up several auctions for them since the TI-8X line of calculators is not one that I actively collect.
I try to use all of my pens equally, but the most conveniently located is a Hongdian 1851 Forest Purple EF that my wife gave me. I keep it inked up with iroshizuku murasaki-shikibu.
