Its a good way to waste a couple of math classes 2003-12-14 11:42 pm Anonymous mirageOS is not an OS, it’s just a shell… 2003-12-15 12:08 am Anonymous I remember programming, in ASM, for my TI-83 when I was in high school, about 7 years ago. 2003-12-15 12:23 am Anonymous I spent 180 bucks on my TI-92+, why on earth would I want to do this? Only if it kept all the functions but made things a bit easier to navigate. Granted there have been better hacks for it out there, like overclocking it to ~25mhz, or doubling the memory in it. I know I have had it churn problems for 1/2 hour before, those things would have been nice. 2003-12-15 1:15 am Anonymous Everyone knows that the best use of Programable calculators is to bring notes into engineering exams so you don’t have to learn everything. Too bad I can’t afford one. 2003-12-15 1:37 am Anonymous why, typicaly there is a sheet provided with equations or you can make one. Also the time to put stuff in a calculator isn’t worth it. Also good number of my engineering exams don’t allow calculators, so no luck there either. And besides, I want to think most people are honest, then again I do no some that arn’t. But I rather fall by trying the honest way then pass cheating. I may not have he best grades but at least i earned them and no my stuff compaired to those with better grades. 2003-12-15 1:44 am Anonymous I was a Sr in HS 7 years ago, and I too remember messing around with my TI-85, playing various z80 asm games, and disking around with asm programming – I learned a lot about assembler from it 2003-12-15 2:24 am Anonymous I don’t think my girlfriend would have been too happy if I swapped the OS on her calc.. :o) She has a 89, I just have my old 83.. It (almost) gives me a correct answer every time.. 2003-12-15 3:32 am Anonymous A while back I was a lab TA. I remember a couple of students goofing around on their calculator at the end of one lab, so I asked them what was so interesting. … I’d never seen p0rn on a TI until then. 2003-12-15 1:10 pm Anonymous Notes: There have been other OS before this one running on the TI92+, some of them even with windowing and multitasking support like e.g. Prosit. http://clapcrest.free.fr/revol/ti68k/prosit/shots.html Also check out the website of the TI-Chess Team at http://tict.ticalc.org/ Under “Projects” you’ll find a pretty nice 3d-engine, a very good chess and many other interesting things, as well as some nice programming tutorials for the TI. 2003-12-15 11:31 pm Anonymous Is there anything like an alterative OS for the 83Plus? My wife has an “extra” one of those I could play with, as long as I didn’t get caught. 🙂 -Bob 2003-12-16 6:52 am Anonymous Yeah i have a TI83 too. I never liked the damn thing but it was required for math lessons. I’ve found some software on the site for it. Quite a lot. But i already had software for it… anyway, perhaps you find something useful on it? 2003-12-16 2:50 pm Anonymous This is an expensive toy, but still, kinda cool, since it takes up so little space. I wonder if any of the BIG OSes are watching.
