Only works with [H], but works with all strings. I've seen it on every OS, for every variant of 83/84 I've had access to.

Interesting.

The TI-OS hides some strange stuff

hmm a glitch i know of in 2.43(i think) involves only being able to select one y equation in y=  each time you press another one it turns the first one off  no clue how to trigger it though


workaround :ram reset

Thats not an fPart glitch, its a cube root glitch.  Try storing the cube root of 64 to a list, and then go and view it in the list editor, it should look like 3.999999999999 or the like.  fPart see's this, and due to rounding on the home screen, displayed the decimal part (.99999999) as a 1.  There is a way around it by calling round() on the cube root function

This effect is also apparent when doing high precision calculations such as Log(6)/Log(2) and can be atributed to round off errors :(

I've had it by repeatedly adding 1/3.  It took me an hour to find the error in my code.

To see a number to its full precision, use that variable in the solver.


This is a really nice thread.

Here's the infamous OS 1.13 PRGM menu scrolling glitch in action. As you will see, I did a RAM clear prior triggering it, and the programs I have on my calc are Illusiat 8, 9, 10, 12, Mana Force and Metroid Pure. None were ran. Look what happens if I create a new/edit a program then from there select a program from the PRGM/EXEC menu!

If you thought by programming in pure BASIC, you were always safe, think again!

EDIT: And now, as 2nd screenshot, the infamous Equ>String( glitch present on OS 1.14 or older, even on the older 83 from 1996!

=O

Wow!  Those are some epic glitches.  This first one looks to be really irksome.
The second one is just insane.  Wow.  DJ, what button did you press to get the crazy scrolling inverted odd text?  Was it graph?  Was it down?

Wow...
*ZTrumpet can't believe that Ti failed that hard-Even without programs you could FREEZE your calc...

See the first page of this topic, the glitch involving Equ>String should explain what to do to trigger it. Do not try on a real calc, though, in case

The Equ>String( glitch is a pretty bad one.
But provides awesome screen shots to laugh on TI mainly because it is present in that many versions of TI-OS.

Thanks!  Does it brick, RAM Clear, or Mem Clear?  Edit: Never mind: the first post explains it. :)

idk how bad it can get on 1.12 through 1.14. I heard stories about the glitch being much worse on older 83s and 83+ OSes, tho
