Detached Solutions Releases MirageOS v1.0 for TI-83+
Posted by Eric on 26 July 2000, 08:13 GMT

MirageOS v1.0w00t. That's all I have to say. Wait, no it isn't. The newly formed Detached Solutions, made up of various members of the TCPA, has released both their new website and their long-awaited shell, MirageOS, for the TI-83+. What's so good about MirageOS, you ask? Well, for starters, it's a FLASH application. It contains a gargantuan number of features for both users and programmers, and supports both Assembly and BASIC programs. It even includes TI-82 emulation for Ash and CrASH.

You can download this uberleet shell here or visit its home page here. In addition, a huge number of ports and new programs for MirageOS have either been released or are currently in the works.

MirageOS contains a huge number of features that are quite revolutionary to TI calculators. A sampling of these is below:

  • MirageOS supports many different program formats, including MirageOS-specific, Ion, BASIC, TI-OS ASM, Ash, and CrASH. With MirageOS, you'll be able to run more of the programs you need from one shell.
  • MirageOS gives the option of many external interfaces. It provides four built-in GUIs, but you can also have a command line interface if you'd like too. This means that you can make MirageOS look however way you want it.
  • One of my personal favorites is the tasker interrupt, which allows MirageOS to perform many functions while Ion and MirageOS programs are executing. For example, you can use a hotkey to change the contrast, quit and save the game immediately (e.g. teacher key), speed up the game, and even take screenshots of programs.
  • MirageOS contains excellent documentation for both users and developers. You can view its user manual here and see its Developer Notes here.

These are just a sampling of the features included in MirageOS. As you can see, Detached Solutions has obviously spent a huge amount of time on this great new shell, so be sure to check it out ASAP. Also be sure to visit MirageOS's Home Page. Congratulations to Detached Solutions!

This looks like a great prgm (except that i dont know how to get ti82 prgms on my 83+). I have been waiting for a program like this for a long time. Good job.

P.S. I love the password dealy thingy. Now my friends cant screw with my calc if i press on (to turn off) and leave the room.

To get 82 progs to your calc, just send them like any other 83+ program. The Graphlink software is filtered only to see 83+ programs so just in the filename box, type *.82p then hit enter and you'll see all the 82 programs ;)

Thanks, that is easier than renaming all the files with .82p to .8xp extensions

My TI-83+ program will not let me put the Mirage program on my 83+ even. It says it is in an invalid format. Can you help me.

well... i guess since it got deleted, i'll post again... just wanted to say, this is a kick ass shell, and i give endless thanks to everyone involved in the making it :)

nice job guys. I'll check it out (now that my 83+ is back in my hands (don't ask. I'm not to happy either)).

too bad I couldn't get my site up soon enough to help release it.

yeah, basically my admin/host screwed me up. since he knows I'm "younger" (16 isn't bad, is it?) my pages get shuffled to the bottom of the stack...

no graphics...no design...paid for incase they are done though. ack...

plus I spend to much time replying to posts =) j/k

but watch www.megahelp.org...it should be up and running BEFORE school starts...

Steve
ps: uh..dangit. I forgot...it actually had to do with MirageOS....

Hey, I can't seem to get it on my calc. If I tell my Graph-Link program to look for *.8XK*, it says "Invalid Format". If I change the file name to *.8XV*, it still says "Invalid Format". Would somebody please help me, because I think this looks like a great Shell.

Not to demean Mirage OS, but are you trying to say that it is more significant than Fargo, the 82 assembly hack (ASH, CRaSH and Jason Todd's original shell), or even Virtual TI. The 83+ runs native assembly code and it runs flash software without a shell. Besides Joe W. already made his ION shell for this calculator.

I think you are refering to OS-82. I haven't used it myslef, but from looking at the screen shots, CrASH and ASH are much better. It would seem to be that through evealution things get better. I have used ION though and I can personally says that MirageOS is much better than ION. I am hoping the next version will ruduce the 7k ram needed for emulation though. Other then that, MirageOS is clearly the better choice.

I included it since OShell 82, by Jason Todd, was the first capapble assembler shell for the 82. Of course CRaSH is the best shell on the 82 now, and Mirage OS is probably the best one for the 83+. But they weren't the first shell, so in essence, they were not as significant as that of the pioneers.

WARNING!!!

As you may know MirageOS uses an AppVar to store user data, folder structure etc. It should be known that when MirageOS is run this AppVar is unarchived and when you exit it is archived. This writes to the flash, which has a limit of writes.

I think I'll just set the record straight here. First, the appvar is *not* unarchived and rearchived whenever MirageOS is run. We were very concious about keeping Flash writes as low as possible, so the only time the the appvar is written to is the first time you run the application, and when you change options. (And it's not even when you change an individual option, it's when you quit the options screen, *if* you've changed any options, that it's rewritten).
In addition to that fact, we added an option to Mirage to allow those of you worried about your flash to keep writes to flash at near zero. If you goto Miscellaneous Options and uncheck the "Allow Write-Back In Archved Progs" option, no programs will be rewritten to your archive. If you do this, high scores will not be saved in archived programs, but it will *greatly* reduce the number of writes to flash, and speed up loading and unloading time.
I hope this clears up the confusion and stops everyone from worrying about their Flash.

Does anyone have actual statistics as to how much the FLASH can be used? I have a feeling that it is more durable than people realize. I saw something on an HP calculator site about their FLASH memory calc, and it said (I think) that their FLASH would last through several years of nonstop writes. Imagine the batteries wasted! If you have statistics, please post them. I'm curious.

According to AMD (who makes the Flash chip) it should take at least 1,000,000 erasures. According to TI, 100,000. As far as I know, an erasure counts as whenever the calculator garbage collects. That means you've got quite a while before your flash wears out :) Although I suppose it's better to be safe than sorry.

Of course an erasure counts as a complete erasure... meaning every byte of the flash... Its unlikly that a COMPLETE erasure ever happens... I wouldnt worry too much about flash wear...

I have written to the Flash RAM just about everyday for a year. It still works, so I guess it will never die. Who can give out some Flash information for assembly programmers?

Jeese... what are ya'll so worried about??? Dan said that the Flash could handle 100,000-1,000,000 complete erasures... this means that by the time you actually DO destroy your flash, the 92+ will cost about as much as the 83+ and there will be a new calculator that will be as revolutionary as the 92+ is now. So stop worrying so much and use that Flash ROM... it makes everything so much easier.

Sorry, I just get edgy when it even vaguly looks like my flash is being written to. Sorry :(
