In the 81 through 83 as well as 85 through 89, they have an additional port behind them for the viewscreen adapter. I don't know about the USB calcs, tho

My Calc is a TI-84 Plus Silver Edition, i got it in late 2006.
Ran the appropriate tests on it all of them passed, so I'm guessing my calc has 128K of RAM in it.
Anyways the serial number is S-1005D.

that means you are lucky and can use programs like TI-Boy and emu8x to the fullest!

tho, calc84 is working on a version of TI-Boy that will run on newer calcs, which I hear is progressing rapidly :D

Nice, you can use the current version of TI-Boy SE  (and a few other programs mentionned in this thread) :D

Welcome here by the way :)

Hi, I just thought I'd say that I have a Ti84+ SE and the serial is P-0508M . I do not have the extra ram. I know you have pretty much settled on which calculator have and don't have it but I don't think any more info hurts.

Hey and welcome on the forums! :) And no problem. Although now we have figured that calculators past letter G have missing RAM pages, it would be good to see in the future what some calcs with further letters (if any) has to offer inside. It would be weird if TI suddently decided to put more RAM pages in again. X.x

I have a really old 84PBE... BOOT code 1.02, serial thing S-0305B.  It definitely has the extra pages.

However.

I'm not sure if something screwed up on my end or if it's TI's random things that they do for little or no reason...but it only takes up to 10 apps (not counting the finance junk)...?  :wtf:

It's been like this as long as I've had it.

Thanks to the structure of the Flash memory, it's possible to have a substantial amount of "free archive space" yet be unable to install an app.  If memory is full when you try to archive something, the OS will show an error message telling you (a) the largest possible variable you could archive, and (b) the largest possible app you could install.  The two numbers may be quite different.

If you have more than 64k free and still can't install any apps, I don't know what else might be wrong.  Have you tried a full archive reset?

He did, he also tried an OS re-install. I wonder what happened to his calc...

Darl181 can you use all archive but with non-app files?

Just to recommend something that probably won't help, type up this ASM program and run it:
Code: [Select]
AsmPrgm
DB0217F5380921CD
9DEF0A45EF2E45F1
17300921D49DEF0A
45EF2E45DB211FF5
380921DF9DEF0A45
EF2345F11FD021E6
9DEF0A45EF2E45C9
54492D38332B0054
492D38342B285345
290054492D38342B
0024323120426974
20312053657400For a plain TI-84+ it should say
Quote
TI-84+(SE)
TI-84+
Just some reading from the ports that are supposed to give hardware type. Again, it probably won't help, but at least make sure it says what it's supposed to :D
Edit: I will upload a .8xp shortly if you don't want to have to type ;D
Edit 2: Here you go!

Thanks calcdude, will try.

It's correct.
Code: [Select]
TI-84+(SE)
TI-84+
DJ, I try to keep the archive as free as possible to avoid Garbage collects (which I get every two-three hours of use), but once I filled the archive to within 10K bytes about a month ago, when the game part of TWHG became an app.
