Pulling the batteries out has no effect on flash. It is the same as forcing a RAM clear by holding DEL in while you insert a battery.

Darl, I believe that your problem is that you are simply out of memory. The reason that this is not apparent though is that you have 76k left. But that 76k is not continuous. Flash is made up of sectors, and each sector is made up of 4 pages that each contain 16,384 bytes. When you archive something, it is fine if it crosses a page boundary, but it cannnot cross a sector boundary. So that 76k that you see is free is actually just the little bits and pieces left at the end of your sectors.

The reason that you managed to up your limit to 12 is that during all your memory shifting, you managed to get the programs to fit better in your sectors. Imagine trying to fill several large boxes with smaller boxes, obviously, if you do it haphazardly, you will not get as many to fit as you could if you tried some sort of strategy.

Now to make the most of what you have left. If you really want to squeeze all the space out of the calculator that you can, here is what you can do:
1. Send all you programs to your computer (apps don't matter)
2. Make sure your variable archive is clean (a reset Vars wouldn't hurt)
3. Sort them by size.
4. Send them back biggest to smallest
Hopefully, doing this will make the programs fit into the sectors in the most efficient way and you will be able to maybe fit 16 apps on. But don't forget, you only unlock an extra sector for apps when you manage to not use another 65,536 byte sector because apps and programs cannot exist in the same sector.

Have you tried taking out all the batteries, including the backup, for at least 6 hours? That resets a lot of things, including Flash memory (more than a reset does)
That is wrong. Flash is non-volatile memory, meaning that it does not require a power source to retain its information. If you've gotten flash messed up enough that the unit cannot boot, the only way to clear it is via the boot self test.

Have you tried contacting Ti-cares?
They might help. :P

I understand that flash is divided...but thanks anyways.

Now I have Axe 0.4.8 on the calc ;D but the OS still won't send.
You know how in tilp, if you get an error a window pops up with the sign on the left, and the explanation on the right?  Well, I get that when I try to send the OS, but without an explanation.  Just the red sign.
I tried the del thing, so the calc says, "install operating system now", and I tried to send the OS then.  Whoever speaks tilp can interpret this: "Msg: using basic mode while being in boot mode."  ???

You can resend the OS without using the DEL trick (unless the OS was already too corrupted to start up normally)

Tilp refuses to send the OS where it worked before.

What happens if you try to compile an app with Axe? Does that allow you over 6 apps?

Acually, I haven't tried that recently, but when I was working on TWHG it would throw some random error when I tried to compile and it would make >10 apps.

This is weird. I really hope it's not a broken flash chip or something. On my calc I got weird issues too, but not this bad. Compiling apps on my 83+ freezes the calc or puts junk in the Y= menu and doesn't create the APP.
