Does anyone have or know where I can get old updates? (before 2.05) I would like them for testing.

You can e-mail TI, and they will send which ever one you requested. I did that for AMS 2.05

Could we ask TI to e-mail us 2.09?

<me>Or</me> you can download it from their site.

Along with a 9MB program TI-Connect? No thanks.

Or from here: http://epsdownload.ti.com/ download/delivery.asp? bn=2708522&fn=1&NAME=OS209.89u. delete spaces.

-W-

Which is, in fact from, TI.

Thanks

What e-mail address would we use to ask them? How big are the OS files? Are they less than 6.0MB? I have a plan...

Think: Does your calculator HAVE 6 MB flash mem? No? Then I doubt it has enough mem to have a 6 MB OS on it.

(It is a little less than 1 MB. Don't ask how they fit it on your calculator.)

How do they fit a 1 mb file on my calculator?


(P.S. I have 2.09 and i think it works fine. I never had 2.08 cause of all the problems people were talking about.)

The calculator has 2M of flash ROM

I'm not sure about the 68K ROMS, but the 83+ OSes come in IntelHEX encoded files (meaning they are more then twice as big as they are on-calc). I've even seen OS files that had a license agreement in about ten languages in it, then the file gets really huge.

So that's why those 16K apps all come in different sizes...

Not really. If 16 kb of raw hex is IntelHEX encoded, it's always exactly the same size. Also, I've never seen an *app* with a copyright inside (doesn't mean they don't exist of course, but surely most just have the app data).
The reason 16 kb apps come in different sizes is because they are not 16 kb. The way the Flash chip works, and how TI OS executes apps, they always have to take up a multiple of 16 kb of flash. That means no matter if it's actually only 1 byte, or exactly 16384 bytes, it will always take up 16 kb, when on the calc. The computer file on the other hand, only has the data of the app, so the size differs with the actual size.
Note: your typical app would ideally be close to, but just under, 16 kb in size (so you won't waste a lot of space). Due to IntelHEX, that becomes roughly 40000 bytes. If you see a .8xk file that's under 40000 bytes, it more than likely is a 16 kb app.

All of the TI apps on the TI resource CD that came with my calculator contained copyright details (the only com up if installed via the old software, though).
Also, some of my apps show up in Windows Explorer as being 58K or so, but are only 16K ones. Why didn't TI use a 8K ROM paging system :( It would free up so much space on my measly 160K (as of speaking, I have 2K free ROM... not good!)

Ah, that explains it then, I only took a look at the ROM on the CD, not the apps.
They couldn't use a 8 kb page system as that would have meant a complete overhaul of the entire design of the calc (AFAIK, all the 8x calcs use a memory model based on 4 times 16 kb). The problem is that if you've got 8 kb pages, then you'll have two app pages in one "memory page", meaning that the app won't know beforehand if its code starts at $4000 or $6000 which would really complicate programming.

Do you mean 68K apps?

No, not 16K as in MC16000 (does it even exist?), but as in an App that fills a single ROM page, which (on the 83+, at least), is about 16KB in size.

I knew it was one of the two, it just seamed like you ment proc type. Oh well.

On the 68k it is very different-Go into MEM and check whether the Apps size is an (octal!) multiple of 16k after you force Garbage Collect.

When it gets to the calc it's 67665 (or something like that once the unnecessary localizations are deleted).
