CN02302818 Worn Manual(s) My second calculator. A pleasure to use. I've kind of abused it physically with my tendency to tear everything apart and lack of proper skills at the time. Luckily I've managed to restore it to full working order.

The BASIC language has a lot more features than you'd find on a TI, like sprites for example. The ROM has a couple games as easter eggs.

Belonged to my dad.
I 0196 C 13613630 4.0 Fair My first ever graphing calculator. This is the machine I learned to program on.

Belonged to my uncle.
I 0998 pre-A VS041684 2.09 Good 2021-02 I don't use this much since I got a V200 shortly after. It's pretty clear that the interface was designed for the 92-series form factor, so it feels a little clunky to use, although I'd still take this over the Nspire every day of the week.

Bought from a Greek seller on ebay, might have been owned by a French person before judging by the single program that was on it.
P 1109 K 2428002247 3.10 Good 2021-04 My daily driver, I love this thing. Gorgeous design.

Bought from a Serbian seller on ebay. It came with some popular 68k games already loaded.
P 0611 C 2068012410 3.1 CAS Fair 2013 Boring machine, not a very practical calculator. The menus are annoying to navigate and the keyboard feels very crippled. I wish it didn't drain the battery to the point of not turning on so quickly. Older calculators with disposable batteries last forever.

I got it for my baccalaureate and did some ndless development on it.
S 0107 G 2355005976 2.43 (heavily patched) Fair Manual(s) 2010 My high school calculator. Fond memories of this machine. Was my main until I got 68ks.

Bought sealed from a German seller on ebay for much less than retail price.
I 0401 pre-A 1031001795 1.19 Broken 2013 Bad screen cable due to carelessness, further damaged while trying to repair. Unsure if it could be saved. It's the launch revision that drains fresh batteries within days.

Found in the schoolyard.
I 0803 A 1274V00330 1.19 Good Box, Manual(s), CD(s) 2014 Very pretty. It's been my daily driver for a while but I went back to the 84+ for the superior screen. Otherwise I prefer it in every way.

Found this gem complete in box on leboncoin and paid some 50 euro for it. The box was opened and weathered, but the contents were brand new.
It came with a few neat things like a transparent projection sheet of the calculator and a huge poster.
P 0510 G 2597029720 Fair 2013 Stupid model that shouldn't exist.

Bought off a schoolmate thinking I could use the screen to save the broken 83+SE. Turns out it's not compatible, and the screen is even worse anyway.
