I really like the TI-89 Titanium, as it is very useful for higher level maths later on, and includes many helpful apps and features for other types of subjects. And Mario 68k. Although its implementation of lists and matrices is a bit odd, it is still a nice calculator to have.
Oh, and time to update my list a little:
TI83+
TI84+
TI84+CSE
TI89 Titanium
Woot woot: 3 more calculators since my last post here.
A TI-89 bundled with a TI-83+ I was trying to buy on eBay unfortunately went for 50 cents above my $13.30 bid last night. Granted, neither one was working, but both were in good cosmetic condition, so I think they were fixable. eBay can be a very good place to look for calculators, as long as you're (1) patient and (2) willing to snipe.
Just make sure that there's no missing columns on the screen. Those are super annoying and aren't directly repairable, and they tend to plague cheap eBay calculators.

Just had one my 89s going bad with this exact problem the other night It also seems they use the same kind of ribbon cable as the Voyage 200 which is impossible to repair.
You're really keeping up with all those TI-82s! I'm sorry now that I sold off about 10 to 12 TI-82s a year or so back; I will try to look through the ones I still have to see if there are any that would be useful to your OS-finding efforts.
I have a TI-84+ CSE. I also have a really nice scientific calculator that has 40 scientific constants stored on it. This calculator can also do 40 conversions. I also have a basic 4-function solar powered calc. I will post pics later. These last two are Casio.
Thanks to Shaun, my collection has gained some new additions:
- CBL 2, with some probes
- Casio CFX-9850G
- Casio CFX-9850GB Plus
- Casio FX-9750GB
The Casio CFX-9850G wouldn't turn on, but luckily, it was an easy fix. There's a small switch in the battery compartment that is physically turned off when the battery compartment is unscrewed, and prevents data loss when the main batteries are removed. I simply soldered across the contacts so that it's always on, even when the battery cover is removed, and voila, the calculator turned on.
I also have a pre-revision-A TI-84 Plus Silver Edition that will be making its way to Ivoah, from which I took photos of the mainboard. I haven't spotted anything particularly interesting yet, but the photo is below in case any other eagle-eyed EE finds anything. I have higher-resolution photos if needed.
