TI Calculators / Flash apps for TI-89 series
« on: July 29, 2017, 04:32:26 pm »
Just wondering, why is it that on ticalc.org there's so few Flash apps for the TI-89 (Titanium)/TI-92 Plus/Voyage 200? Are they like super hard to write or something? They seem much more user-friendly than ASM.

Other Calculators / Anyone know of an archived version of that "Fun Number Theory Facts" thread?

You know that thread where the signing key for the TI-83 Plus was revealed? It was called "Fun Number Theory Facts". I've been unable to find an archived version of it. Here's the link to the thread, which is now broken. Looking on web.archive.org gives me most of the thread, but the earliest version has the OP removed.

HP Calculators / What's wrong with my HP 49g+?
« on: July 13, 2011, 09:38:38 pm »
I was fooling around with the built-in assembler on my 49g+, and ran this program:

!ASM
LDR R0,[R1]
@

It reset and the memory was cleared, but it was suddenly very slow. I did a soft reset (ON+F3) to see if that would help, but now the screen is blank. I tried leaving the batteries (including the memory backup battery) out overnight, and that didn't work. I also tried following the instructions at http://www.hpcalc.org/hp49/pc/rom/ under "If it fails:" in case the firmware was erased, but no menu appeared.

More than a month later, I tried turning it on, and it appeared to work fine. I was able to perform several soft resets. Eventually, however (the next day) it started getting very slow again, and now the screen is blank again. What should I do?

To reproduce what I did (at your own risk!):

256 ATTACH "!ASM
LDR R0,[R1]
@" ASM EVAL

Casio Calculators / Why does the diagnostic menu popup say "factory use only"?
« on: July 10, 2011, 08:53:17 pm »
When you press the key combination to trigger the diagnostic menu (calc off, hold OPTN+EXP+AC/ON) the following popup appears:

=DIAGNOSTIC MODE=
Factory Use Only!

 Press : [EXIT]

The way it says it's for factory use only, coupled with the fact that it tells you to press EXIT and gives no indication on how to open the actual menu (F1, 9) makes me think Casio has some reason why they wouldn't want the end user entering the diagnostic menu. Why would this be? Sure, it clears the main memory, which could be an inconvenience, but as soon as you press F1 it asks you to confirm.

Casio Calculators / About 6 months since the PRIZM was released and not many threads?
« on: July 10, 2011, 03:47:14 am »
How big is the PRIZM hacking community compared to that of, say, the TI nSpire? Or the TI-89 a similar amount of time after that was released?
I don't see many threads in this section of the forums; there's only 2 pages. And there also aren't many games available. Does anyone have any idea why this is? I just bought my PRIZM today, so I may seem like a noob.
