Couch find TI84 Plus

Friend of mine bought a couch off of Facebook marketplace. Was cleaning it up, vacuuming beneath the cushions and found this TI84 down in the crevices! 5/06 build and had dead Energizers that expired in 2014, so possibly its first batteries! Luckily, there was no corrosion. Put aaa's in from my Casio CG100 and it fired right up! Os 2.40, so most likely never been updated. Should I update to 2.53MP, or leave it OEM? I already have a TI-84 Silver Edition Teacher ViewScreen calculator that I used with my old TI Presentor.

Best Place to Sell?

I've decided I'd like to sell my 1985 Casio CK-200. However, lacking experience selling electronics online I am wondering what the best platform might be for this rarity. There's Ebay, of course, but anyone have any other suggestions I can look into that might be better suited? Thanks a bunch!

Anybody can help me find what this was made for

I bought this clock at a carboot sale, and the seller said her dad worked at IBM, so I am curious to the origins of the clock

​

It also doubles as a calculator

300ES Plus now a free emulator in ClassPad.net in the US

Was using ClassPad.net today for a graphing calculator on my Chromebook, and saw an emulator of the 300ES Plus newly added at the top of the list. This may be US-only or not... either way I thought I'd share it. If you are on your phone's web-browser, it will make the calculator full-screen.

TI-84 Evo screen...

Took forever it seemed, but finally received my Teal Evo from Amazon. Ordered it April 28th, but became Out of Stock.

Is this uneven back lighting on the right side 'normal'? My TI rep said he would send me one to exchange when he received another Teal one, which are being sent out later this month.

I just want to see if this is the norm or not. The left edge of the screen is uniform in brightness. Changing the brightness of the screen had no effect on making it better.

Casio 9860GII added to the collection... and SD questions.

Picked up this drawer queen off ebay. Don't think it was hardly used and included the QSGuide and cord. Love the larger screen and backlight option, similar to my Slim. Found the power graphic 2 version too.

Ideally, I was looking for the SD version. Which version has the most apps, SH3 or SH4? Also, can you store programs/apps on the SD card to run, or do they need to be in the calculator memory?

9860GII SD come in SH3 and SH4 (Power 2) with both being premium prices on ebay. Though Graph 95 (French version) are cheaper. Besides the test mode, are there any differences between the international 9860GII SD and the Graph 95? Does the Graph 95 have both SH3 and SH4 variants?

Thanks!

Realistic CD-1700 won't spin the CD.

This is my first CD Player my sister bought me for my birthday in 1989! It has always worked. I stored it in a dry loft of my barn. My son made his fix mix cd and wanted to have a player in the living room. Now, it will power up, open and close and the display all work, but the cd will not spin. Is there a fix for it?

Didn't know this existed until a couple months ago here on Reddit. Found this fx-600 NOS in TX on Mercari. Like a 40yr old time machine!

I still think there would be a market for a large display desktop scientific. Just the difference between a 991CW and the Graph Light is better, but needs to be bigger! Will compare it when I get home. Why do the accountants have 100s of desktop calculators to choose from and we have only 4 1986-1988 Casios? Lol.
