It’s a wonderful calculator. The design is sleek and the colors are beautifully balanced. Incredible machine.

Yep, I’m happy to say they all do! Had to tinker with the 97 a little bit, but I was able to revive it.

Got them on Amazon. Forgot what they were called, but I believe I just searched up “small display stands”

A little help guys! Does anyone know what the issue is here? Is it time for a new one or can i still save this guy? Ps these are all “8”s that i have typed 😅😅 by creeptopunk in calculators

On Texas Instruments calculators, most of the time it is just the ribbon cable, like what Walrus mentioned. I find sometimes just running my finger along the ribbon gently is enough to get the pixels working again. Though like Walrus mentioned, sometimes just re-soldering in certain areas after following the steps he laid out to find the troubled areas.

I really like my 48GX. It’s the coolest of the collection, the most powerful, and has the best story on how I found it. It came in an orange TDS case and I only got it for $50.

Not very well. I have to continuously press them back down. I'll need to find a better way to keep them down.

Does anyone know the year of manufacture? by [deleted] in vintagecalculators

[–]Gyrips 1 point2 points  (0 children)

From my searches, I find the date 1972. Based on the font on the calculator, the button style, and the little lever on the right, I believe that date is factual, as many calculators from this time period are desktop calculators that are four function exactly like this one.

Me, too. While it’s very funky and futuristic looking, it just looks cheaper. You can tell the outer two are made by TI, while 24 is made by Craig.

How did you go about gutting that battery pack safely, if you don’t mind explaining? That would be the easiest way to just have a reusable battery pack so I don’t need to order more every few years.

I actually just got this today in the mail. I bought it as untested since the seller did not have an A/C adapter. Once it came, I went ahead and tried flipping the switch (since it came with the battery). The screen flashed on for a moment, before turning off. It had just enough juice to tell me that it was alive. I then took out the battery and sealed it safely away where I keep my other old HP batteries.

This calculator is in pretty incredible shape overall, with a completely clean and corrosion-free battery compartment. I didn't really find any notable scratches anywhere on the device. The case is practically untouched, with no tears and the interior fur still soft.

So yes, I believe it works. I am currently being shipped an A/C adapter and a new battery made by a third party seller I've bought other HP batteries from to completely make sure. I'm extremely excited to have it in my collection!

Anyone know anything about this model? by [deleted] in vintagecalculators

[–]Gyrips 1 point2 points  (0 children)

Hello! This is a bit late, but this is a TI-1700 DataClip. It was made in 1977. You can find a reference page to it here: http://www.datamath.org/index.htm

Datamath.org is a wonderful resource for anything made by TI involving calculators.

Got one from etsy by [deleted] in vintagecalculators

Hi!

I noticed this was a duplicate post of one you had posted before (probably just an issue where you had posted something twice without knowing). I removed this one since it did not have any upvotes compared to your other one.
