Thanks for welcoming me, Art_of_Camelot!

I shouldn't have dogged the 68k series so early on, then. I never went and took the time to explore the archives on ticalc, mostly because I never go there unless google directs me there with programs only found there. Apparently, the file hosting on that site is the preferred method of sharing things. I don't want a 68k series calc because I've got absolutely no money to speak of, ever, period. I want to get myself a nice calculator to continue my hobby, the nSpire seems the perfect fit. When I get a job that I can use for things other than things I need, I'll put a little money into the hobby if I still like calculators then. :) In that case, I will definitely get an 89, because obviously I was unaware how programmable they are!

I know enough about Axe that it's okay not to go in-depth. I use it to get something done quickly when Basic doesn't suit my needs. It's probably my favorite language :) I didn't know that Ion was executable natively, however, so I'll have to look into that because Ion rocks.

Few things: I either like to have a well documented calculator that everybody loves and knows lots about with lots of utilities written for it, or I like to be a pioneer in documentation for the calculator. I see that the 8x series and the 68k series have been beaten to death in that aspect. :) We don't know everything, but we know so much in comparison to any other calculator, I never have to test things for myself. I can just go to WikiTi.

The nSpire could always use someone like me to screw around and learn more about it! It's under-documented, but with a little push in the right direction, something could be done to make development a lot easier for it. The z80 series is the best all around, but I don't think the nSpire has been pushed to its limits like the 84+ has. So what makes a CAS better than a regular calculator?

^CAS Info.

I'm glad you realized that the 68k calc's aren't so bad. I perfectly understand that you now rather buy a Nspire first, and I'm fine with that. :)

I think that if you want to use the calculator for math-things, it would be a shame not to pay a bit extra to get the CAS, since I'm used to it on my TI-89, and when I go on a Z80 I fast notice I really miss it.

As I said I have a CX CAS, its better because it has math functions that the lesser calcs dont. It can expand things like binomials and you can do things like solve equations. It can do a lot more, I just dont have time to get into detail.

There are still some surprises in the TI-Z80 hardware: for instance, until recently, the community didn't know how to bypass some execution limits (the corresponding knowledge was gained when TI made a silly change which was soon worked around), and of course, the 84+CSE is appearing. There are fewer surprises in the TI-68k documentation. But indeed, the Nspire's hardware is relatively less well documented, and the platform hasn't been pushed to its limits.

The Nspire's CAS could do even more, through native code, which is possible on the TI-68k's CAS but not really on the Nspire. There has been little work in that area, besides me showing in 2011 that the code base hadn't changed much since the TI-92 in 1996, and Excale making a bit of progress through a Lua extension in 2012. We don't have enough insight into the calculator's document format, we only know that Ndless documents are not well-formed for the purposes of meaningful interaction with the CAS.

Not trying to sound biased, but the classpad's CAS is less buggy and more powerful than the nspire's. ;)

[Citation needed], please ;)
A fact is that the HP-49 CAS outclassed the TI-68k CAS in several areas, and another fact is that modern versions of the Nspire's CAS are buggy; but the Nspire's CAS contains several enhancements over the TI-68k CAS. Do you have a comparison of the CAS engines of the Classpad and Nspire similar to ti89vshp49.pdf ?

I'm going to be on at splotchy times and I may be out for several days at a time. Vacation. 8)

I don't have the comparison PDF although I must say, I want one! I don't think one exists though...

zStart has been around a while with it's nice execution limit workaround/exploit. I've been looking at his "speed increase tool" that takes off the delay set by TI lately and have wondered about actually having a setting that slows the calculator down significantly, for TASing (which WabbitEmu doesn't do justice for. Speeding the calculator up is even worse.). So, I know that there are some things which have, and some things which haven't, been discovered and/or documented. Universal flash access across all 83/84 calculators is also a relatively new thing!

The Ti84+ has a solver, but I find that I have to work with it before I can get what I want.

Well, I am intuitive enough to do some random stuff and logically assess information based off of it. Need help documenting the nSpire? :)

What is a ClassPad? I have heard of them and googled it, but I really DON'T know enough about them, not that I can ever get one until I have enough money.
 ---Even when I do, I'll be getting an 89 first. :) 68k series actually rocks, from what I can tell! They aren't crappy 84s, and they aren't that terribly different. They do have major differences that make them awesome, though, and they do require a hack (which makes me feel kinda cool to use it to program.) depending on the model. I won't rule them out, but I want a nSpire because I think it will be better. :)

I just want to say that it's very cool that you edit your posts, instead of double-posting(that's a rule here).
Many people don't do that, but you do so: Well Done! :D

Also, I find it cool that you changed your opinion about the 68k calculators. That means you admit you were "wrong", which many people will find hard to do. :)

I hope you have a nice vacation.

MirageOS had a slowdown feature which worked for programs that didn't mess with the interrupts. It was [On]+[Graph] or [On]+[Y=] or one of those buttons. The ClassPad is a Casio calculator that's got a touch screen. I think a color screen version is also in the works.

Stefan appreciates me and my forum etiquette! :) I tend to ramble, though! I stick my nose into things I know nothing about so I can learn more about those things. I watch for proper mechanics and comprehension. Forum posts are like my literature class, as I am home-schooled and don't do as many papers as other people do.

I find that my "wrong" opinion (Interesting how opinions can be, isn't it? ;) ) of the 68k series was simply an error in judgement. I formed a strong opinion far too early and without much knowledge at all. MirageOS has no such feature, at least none that I can tell! I have used it for years and recompiled it to my liking, even rewritten some of it with what little I know of ASM. I hacked Mario 1.2 today and made all enemies stop existing. The goal is counted as an enemy. Whoops. :P Is there a Mario 2.0? I heard there was.
ClassPads look crazy..

Are there PDF readers for the nSpires?

I don't think I can agree, I've never had problems with the CAS, and I'm not sure about it being more powerful, I'd have to try it first.

Not really. There is nothing to reads a true pdf, but you can convert your pdf as an image and open it with mViewer (which has a zoom feature and all ;)).
I own: 83+ ; 84+SE ; 76.fr ; CX CAS ; Prizm ; 84+CSE
Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

chickendude: I just edited the hex using several tools like calcsys and then resigned the app. I don't have the source, but I have found it before!
I had NO idea MirageOS had so many features :O This is amazing! I took this app apart and didn't know about this stuff :)
The CAS sounds like it is just MathPrint for nSpires?
Keep trying.

No, a CAS is capable of solving very complex math problems, all versions of Nspire have a much better, cleaner version of math print
