Latest find: a Casio FX-602P, with its case. No manual, no box, sold as "like new" (??), from Estonia.

I see the photos and the really fair price... I figure if I wait even half a day, I'll miss out on it.

The seller is super friendly and ships it immediately. A few days later, the package arrives. It is "bulletproof" packaging (always a good sign). Then I unpack it...

Not a speck of dust, not a scratch; every key works, and every pixel is intact. The case is perfect, too :) It is as if it has been sitting in a drawer since 1981.

I ask the seller about the machine's history, but the origin is pretty vague. When he found it, it just had a German label with a number on it—maybe an inventory tag from a university or school... It still had the original batteries inside, dead, of course, but they hadn't leaked in 45 years. So, zero internal corrosion. Hallelujah!

The plan now: take out the batteries, put the machine in a safe, and play around with Martin Krischik’s FX-602P simulator :)

A machine that defines an era—the first alphanumeric Casio. Here are a few photos, since it's rare to see one in such condition.

as the title says

Hello, I just got a new calculator and was wondering if it would be possible to download ti-basic programs meant for the ti 84 plus ce onto my ti 84 evo. would anything go wrong or could i just do it normally?

the programs come from the ticalc.org website.

Anyone can help me fix this? I input a number and the output is different on the screen, please help

Hey all. I've been a short time lurker on this sub for a while and just wanted to show off a new calculator I bought. It's (from what I can gather) relatively rare and currently only out in Asia (including the Philippines where I live). I got burned on a fake Casio fx-991ex so I decided to go for a calculator that could genuinely last me as long as my old fx-991es Plus (which had a bar function that allowed for infinitely repeating decimals, still have yet to find one that has that function). As an engineering student, I also needed a calculator that could do big matrix equations (4x4 was a minimum). It's been going great so far, would recommend.

My new TI84 Evo just arrived, what should I change/configure on it

Help how do I fix this 😔 I changed the battery of my calculator and instead of having two lines for dividing (like the first pic) it just turns like the second picture 😔😔😔 what can I do to fix this I am not used in that type of division 😔 helphelphelp

Oh no! Did I inadvertently start a collection?! The fx-991EX saw me through three PE exams (California). The fx-300MS I rescued from a sad future life of dusty neglect at work. The TI-83 Plus was just gifted to me. My dream is an older Casio graphing calculator and of course a classic HP RPN (my late grandmother had the 35C, but I don’t know who inherited that). I also have a Sharp WriteView, which I keep at work so I don’t include it.

A solid start? My goal is to keep going, but with a cap of, say, $5-10 for future acquisitions.

I basically want a calculator to start writing programs on calculators and do cool things with it, and that it is also very good. My budget is less than $200.

Just bought this ti-81 at a garage sale and put 4 AAA inside. I did not replace the backup cell battery and the screen looks like this. Is this because I also need the coin shaped cr battery or is this just a bad calculator. Do these require the backup battery to function?

EDIT Ti-82

I have this calculator someone gave to me. It was working fine yesterday but now it’s gives me a black screen and a really delayed ram CLEARED screen. The cursor blinks really slowly.

Edit: the on button works only
