There have been rumors going around about being able to increase the available archive memory on your 83+ series calculator. As it turns out, this is true.
Hmm. I disassembled the source code, but I don't know what many of your equates are. The best thing I can say so far is that the program seems to mark unused or swap pages part of the archive. I guess the instability occurs when the OS tries to use a swap page that it also thinks is archive.
Oh, I actually solved it? Cool. I figured I only had part of it, and someone else would build on what I said.
Anyway, you set the solved date to March. Might want to change that.
On with the puzzles! :)
DO NOT LOAD THAT ON TICALC!!!!!!!!!!!!!!
I nearly destroyed my calculator trying that last year. I deleted an app without thinking, and it went into an infinate Defrag. I spent days trying to figure out how to fix it (I don't even remember what I did that worked). I did some combination of 3rd party OS's, self-tests, and sending TI-OS's to the calculator and it finally worked. I emailed the author to take it down, but he never responded.
Harm can come of it if you do a garbage collect. Mine was borked pretty bad. I also have a quote by BM (the maker of PongOS):
"(I'm constantly hearing about people who are trying to "expand their archives" by means of some bug in TIOS that makes it think there's 64k additional space. You certainly could store more data if you added illegal archive sectors. But you would also crash the thing pretty badly at the next garbage-collect. So don't do it. If you have an app sector that you want to convert into archive, you can erase that sector.)"
Now the question is would it be possible to do this with the extra ram that se/84 calcs have... and have it be more stable.
No, because this bug utilizes flash rom, not ram. Now, if you could upgrade the rom chip so that the calculator really does have 64k more rom, this bug might work AND be stable. But, I'm no good at soldering and working with circuits, so I'll leave experimentation to someone who knows more and has a calculator to spare.
Then how did mine get screwed up so bad?
I tested this program and it sent my 84SE into a garbage collect loop. now, after hours, the calculator is still garbage collecting, and there's no way to stop it, even if i pull the batteries.
Is there any way i dont know to stop it without taking apart the OS and stuff?
