TI-84 Plus OS
« on: August 04, 2010, 07:10:08 pm »
Currently I have the 2.40 OS. I didn't get 2.53MP because of the issues with it, but I am considering upgrading to 2.43. Are there any good/bad things to upgrading to 2.43?

Not really, I don't think. But I'm pretty sure all the issues with 2.53 that we know about have been fixed in one way or another.

2.43 is probably the best 84 OS, with good compatibility.  ;)

none of the pretty-print and all that(which you can get elsewhere if you really want it and avoid the terrible-terrible speed decreases)

Good things about 2.43: compatible, fast, no(t that many) bugs.

Bad things: yeah, there's no prettyprint, as schmibs said, but it made 2.53 slow down (a lot).

Agreed: 2.43 is the best so far.

EDIT: In case you didn't download it, here it is to save you time.

Yup, OS 2.43 is the best, well except for OS 0.46. ;D

I have it now, and I applied the patches also  :D
Now I won't have to worry about ERR:VERSION!  :)

Wait, what? TI still has it on their website? I knew it was available from Web Archive, but I would have thought they would have gotten rid of it elsewhere.

I'm going to download it now, so if/when I get an 84+ I don't need to resort to other means if TI has gotten rid of it by then.

EDIT: What was OS 0.46? Was it the one that had experimental printing capabilities?

The userbars in my sig are links embedded links.

And in addition to calculator (and Python!) stuff, I mod Civilization 4 (frequently with Python).

Yup.  I think we got it because when TI updated to one of the OSes on their site they accidentally uploaded .46 for about a day.  We were lucky and got it. ;D

Didn't it only half-work or something, tho? If I remember, a lot of stuff were broken :P. I would be scared of installing this on a 84+ if I had one.

Slight bump.

I actually still use TI OS 2.22. For the simple reason that every OS since 2.30 had that "feature" of not connecting the dots on the graph screen when there is an asymptote at the cost of a 300% longer drawing time :P

Did that ever get "fixed" by anyone? I remember reading about why it was so slow and I saw suggestions to somewhat fix it, like changing Xres to 2 instead of 1. But that results in my sine functions having a slight dent into them =P
Unpretty Integrals
This program gives you a graphical representation of the "fnint(" function, which allows you to calculate definite integrals. It is extremely similar to the functionality MathPrint provides, minus the extreme bloat that slows your calculator down to a crawl.

I forgot. I think Xres was the solution but I don't remember if someone wrote a patch for that.

The slower drawing is an issue in many cases. Some people even use graphing functions in games.

Basically, the major differences between the OSes are:

2.21/2.22 Old OSes. Lack major USB support, but are fast with graphing, and (apparently not) stable.

2.30/2.40-2.43 Latest normal OSes. They all have USB support(ignoring the nspire versions of 2.42 and 2.45). They have the slowdown with graphing, but they're still really stable, and have the most compatibility with the most things. They also introduced push-to-test, a way for teachers to lock the calculator down for tests. You might want to keep this in mind, though I've yet to hear an actual example of a teacher using it.

2.53/2.54 These have mathprint, which in the few minutes I've used it, was the slowest glitchiest crappiest thing ever.

I'm personally running 2.41 on my 84+, but I see no reason to go for 2.43. I can't stand mathprint, though.

2.21 and 2.22 are far from stable. You shouldn't use them, ever. They have sequence graphing bugs (patched with http://brandonw.net/calcstuff/seqfix.zip if memory serves).
