A 84 Plus, a 83 Plus and 4 emulated calculators.

I thought I could post my own humble collection too, so here it is, all of them showing PI:

- Casio fx-92 Spéciale Collège
- No brand, SY-100E
- Casio Graph 100+ USB
- HP XPander (working, very rare prototype of a calculator that has never made it to production)
- HP 48gII (prototype. It's running a TCP/IP stack which you can try out: http://5.196.110.164/)
- HP 50G (with a 64 MB SD Card)
- TI-80
- TI-82 (old model)

Also not shown, a Casio fx-92 Collège 2D modified to run like a fx-500ES.

Soon, I'll get a Casio CFX-990GC and a Casio FX-6910G.

I also got some cables for those calcs and also some documentation about the HP48 series (http://tgz.fr/calcs/docs.jpg). All those calc run on AA, AAA or CR batteries, no rechargeable Li-ion crap.

I have my trusty and only ti84+ silver edition. I will not throw it away even if i get a color calc (which wont be before I go to college).

LONG LIVE THE TI84+SE!!!!!!!

Just added a TI 2500 DATAMATH Version 1 to my TI collection. Found it in an antique store for $5. It had the power supply with it, so I looked around the store for a socket to try it. I plugged it in and it powered on. I tried each key, but the 5 and 6 keys didn't work so I put it back on the shelf and continued to look around the store. I didn't find anything else, so I went back to where it was and picked it up. When I got home I looked on the Internet to see that it was made in 1972 and also that the 2500 was the first Calculator made/sold by TI. I'm glad I went back and got it. I got the 5 key to work just by constantly pressing it, but no luck yet for the 6 key. I opened the battery compartment and there's a hard wired 6 pack of batteries in it. They're really corroded, so I'll have to clean them off. I can get them out, but they're soldiered together and connected to the calculator by 2 short wires.

Don't mess with those rechargeable batts without properprotection. Those are Ni-CD batteries and they are very toxic because the contain cadmium. Also, please post a photo of that calc. I am curious to see it. I also a casio fx 300sa solar-charged calc from when my father was in hi school.I recently got a cheap calc for scool use only: a citizen sr260n.

CalcMax; Here's a picture of my TI 2500.

Beautiful.

Here's my collection (in order of acquisition):

Graphing:
TI-83+ Silver Edition
TI-89 Titanium (HW4)
TI-83+
TI-84+ Silver Edition

Non-Graphing:
TI-30XS MultiView

Accessories:
TI Keyboard
TI Calc to PC cable
Unit to unit cable

(I'll add a picture later.)

I have only two graphing calculators in my possession right now. The first one I got is a TI-73 Explorer calculator, with appearance similar to the TI-83 series of calculators (which I 'borrowed' from my school). The second calculator is a TI-84 Plus Silver Edition calculator (I purchased it from Amazon in 2014). I will take pictures of them and post them here when I can.

What is happening to your TI-85 graphing calculator?

That's just the game that's running on it.
(also, try not to double post, edit you last post instead of making a new one if nobody has posted since your last post )

So are the edges of the screen being distorted by the game, or is this what they call the "leaky LCD" problem? I don't think assembly programs could cause screens to have wavy edges as seen on the TI-85 calculator.

No, from what can see, that is just a program running on the calculator, and sure assembly programs can literally display whatever they want on the screen, so asm preogrammers cna make the edges of the screen funky if they please.

That's cool, I did not know assembly programs could make the edges of the screen wavy and the screen look ghostly.

First of all, the TI-85 has a wider screen than most TI graphing calculators, so the "wavy"ness you see is just more image on the sides of the screen. Second, it's "ghosty" because the colors are inverted, and third, instead of black and white like most calcs, it's display is blue and white.

Well, um, compared to everyone else's collections, mine is terribly modest:

TI-84+CSE

And, well, yeah, that's it 😊.

Woah, that 73E that Ivoah has is running the TI83+ OS??????????? THAT must have been done by the semi-legendary Chameleon program!
Also, where the hell do you get a big calc screen? the ti viewscreen seems cool! I want one for my 84+se, but I doubt it will work ...

Hmmmmmmm... I think my one and only, trusty 83+ wins!

Its odd that I haven't posted in this topic before, but apparently I haven't, so here goes.
TI-84 Plus, TI-84 Plus CE (black)
Various non- graphing calculators scattered around the house.
Numerous Micro USB cables, two unit-unit USB cables, one 2.5 mm unit-unit link cable.
I think thats it.
