Mirage OS

MrPig 19 Oct 2010 00:49

I'm thinking about downloading something like Mirage OS or Doors CS on my calculator (a 84+SE with the new 2.53MP OS) but I don't know much about this stuff and would like your suggestions on what I should get, if anything, and maybe also explain a little what they actually do.

i suggest calcutil, although it is a lot less user-friendly than mirageos and somewhat unstable. maybe try noshell.

basically, the calcs dont know that the asm programs on your calc are asm, so they try to run them and fail. thus, people created "shells" that are sort of like virtual machines that make sure that the calculator knows that the programs are asm and thus treat them as asm programs. if you try ASMprgm(prgm<Name>), the calculator might not be able to do every command and thus crash because a bunch of the shells also have many definitions included in them that allow for amazing programming capabilities.

mirageos is the main shell people use. it has a nice gui with some interesting options

doors is quite new, and i think it is slightly better only because it shows every program, regardless whether or not it has the :" command as the first line (including it can produce some cool icons), and it will tell you whether or not it is an asm program or not (not that it really matters). and theres a mouse! although it can be a bit annoying at times

and get rid of OS 2.53! its terrible! get 2.4 or 2.43. the fastest one i believe is 2.20, but it had connectivity problems.

calcrypto explained what a shell does better than I could, so I will not go further on that. However, I find that using MirageOS is very easy to use, and the ability to choose which programs you want in it is very useful. Also, with it, you can lock your programs and give them to your friends (if they are BASIC) and they cannot edit them. ;)

But my question for you, calccrypto, is: Why should he get rid of OS 2.53MP? I use it, despite everyone saying not to, and I have encountered no problems (that weren't my fault) as of yet. You can easily change from MATHPRINT to CLASSIC just by going into the settings. Plus, my statistics teacher (when I had him last school year) still had 2.43 and I could do somethings that he could not (for example, RandIntNoRep)

2.53 crashed my calc like crazy. omnicalc, calcutil, and i think symbolic were not very compatible. maybe there is a thread somewhere in this site with all my complaints, but i know definitely that ticalc had an article about it
its also incredibly slow at graphing and showing the Y= screen

admittedly, i am a little biased, since i had been hoping for more programming commands, but the math commands are nice. the problem is that i dont use my calc much any more

If you are more interested in the math functions, then go ahead and stick with 2.53MP. But if you program on your calculator a lot, then I say you should get 2.43.

Also, correct me if I'm wrong, even if you set your calculator in CLASSIC mode, Basic programs still run slower compared to previous OS versions.

Re: Mirage OS

MrPig 19 Oct 2010 22:38

you're right, even in CLASSIC mode, there's still problems. I've been thinking about going back to the old OS. I tried out Omnicalc today and really liked it (i found a 2.53 compatible version, but there's still a lot of problems)

Re: Mirage OS

BlakPilar 19 Oct 2010 22:42

Well, I didn't really program anything complex when I had 2.43 (I didn't know about anything other than Disp and Input until my friend gave me Catalog Help) so I can't say that I've noticed a difference.

But now that you mention it calccrypto, yes, I do recall one time when Omnicalc MAJORLY crashed my calculator with 2.53MP. It cleared all of my RAM and Flash. As to the Y= screen, I think it goes "slower" than, say 2.43, because it graphs everything at the same time, rather than graphing Y1, then Y2, then Y3, etc.

So, for MrPig's sake, I recommend either MirageOS or Noshell. As to your operating system, you've seen our discussion, so it's up to you.

PS - Sorry for the late responses. I would've gotten back earlier, but I went out to dinner for my birthday =)

Well I've decided to downgrade my OS, but I can't find any way to do that. Any help?

Re: Mirage OS

patriotsfan 20 Oct 2010 02:09

You'll need to find a site that has 2.43. This is how I did it: use archive.org on the TI website and there will be a download link for the old page.

HAPPY BIRTHDAY!!! ♥

I have had problems with 2.53MP without having any shells. For some reason, I had it freeze and then I had to pull out my battery's. It was kind of like leaving an assembly program in a loop.

I only used it for about a week before I downgraded back to 2.43 because I like to program.

2.53MP is really only noticeably slow when it is displaying stuff.

Same here. I don't need all the fancy features and additional math functions I will hardly use, I just want speed.

Re: Mirage OS

MrPig 20 Oct 2010 02:25

I found a download on the TI site, but as soon as I finished putting it on my calculator, my computer got the blue screen of death. I shut it off and my computer and calculator are fine now, but i don't know what happened.

Re: Mirage OS

patriotsfan 20 Oct 2010 02:33

Hmmm, strange. You might have an old computer I guess. Well then, at least everything's fine and you installed the OS.

Haha, thanks burr and Xeda

I suggest getting Doors CS 7. It has a feature that allows you to run any program (made from any shell) directly from the homescreen (even if they're archived) so you don't have to download a bunch of shells to achieve full compatibility.
Plus, didn't development for MirageOS stop in like 2004?

As to what they do, I think calccrypto summed it up pretty well - they manage your programs, come with interesting little features, and allow programmers to do awesome things if they know how.

Re: Mirage OS

burr 21 Oct 2010 18:19

Doors CS 7 is a good shell, but I think it's bloated with a lot of unnecessary features. If Kerm trimmed it down to just the core features (kind of like a Doors CS lite), I think it would be more practical.

Re: Mirage OS

patriotsfan 21 Oct 2010 19:36

Personally for me Doors CS 7 is the best shell out there. The only complaint I have is that it takes up 3 app spaces. However, if you have a TI-84 calculator, then this shouldn't be an issue. In short, I seriously recommend Doors CS to everyone.

Re: Mirage OS

burr 21 Oct 2010 19:47

The 3 app spaces size is what I was referring to. All of the other application-based shells are just one app space.

Re: Mirage OS

BlakPilar 21 Oct 2010 20:23

I still think that MirageOS is better, one part of it being that you choose which programs can be seen in it instead of having every program shown. And like burr mentioned about others, MirageOS only takes up 1 app space. I have a TI-84+, and no, it is not a problem for me to have Doors CS 7, but I used to have a lot of games and things which were in my archive, so my flash space was valuable to me at the time.

Fair enough - I didn't realize that Doors CS takes up 3 app spaces. I have a TI-84+SE, so space isn't usually an issue.
