Opening a calc?
« on: February 14, 2011, 12:33:00 am »
I've had problems with various keys sticking (arrow keys, clear, a few others) and I've been trying to figure out how to fix it.
I saw an image on google a while back (of course, I can't find it now that I'm looking for it :P) and it looks like I can get to the key hardware by opening it.
I can easily get the screws out, but how do you open the case?  I don't want to make some sort of stupid mistake trying to open it, and there's doubtlessly others a ton more experienced at this than I am.
It's an 84, black edition.

Black edition  ??? I have never heard of this. Anyways make sure you get the screw out underneath the backup battery and then there are four clips holding the case together(two on each side). Use a knife or something and carefully pull apart the clips. It might take awile but eventually they will come off.

Once open be careful with the keyboard because the keys like to fall out and stuff and also you won't find a real z80, but instead TI's version one.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

Okay, thanks
So I pry it at the corners...
@z80man there's silver edition which is gray and the normal, which is black, so black edition.

Black edition= TI84+ (non se is black)

Yes, but be careful. Just read the instructible or google "take apart a TI 84+"

I don't know about a BE, but for an SE, there are 5 clips holding the case together: one on top, two at the sides of the LCD, and two near the Log and * keys.  It doesn't take much force; just stick something thin (a guitar pick works well) in between the two halves of the case and push them apart until the clip pops open.  Once you have 4 of the 5 clips open, the case will just fall apart.

Also, for an SE, be sure to remove the keypad cover first.

Yeah, I have a BE :(
Someday, I plan on having an SE, but I'd have to get it on ebay or something b/c of the lack of extra RAM (which I've gotten really used to)
[offtopic]It turns out that not all BE's are really black... :o

ooh. things like this can be hard to open, and can also snap if not careful, it will require some significant amount of force in the right direction

But yeah it's hard to open these calcs, even the 83+. Also you need the right screwdriver and right size, to not break the screws top.

Yeah, in my math class they lended out those pink ones...nobody in their right mind would steal those :P
Some of them actually have 2.53.  :o
Most are 83PBE's tho...there's a few 82s floating around as well

Yeah when I went to hi school all they had were TI-82s. Students usually had a TI-80, 82 or 83+. I was the only one to have a 83+SE and very few people had a 83 non +.

Now with doorsCS7 a ram clear really does do nothing. My free ram is always 22 kb+ now!

I use omnicalc...dcs7 is just way too large. :P
It works a good part of the time, and if that fails, there's axe backup, and when that fails, there's msd8x.
I'm prepared for this stuff and I "backup my progress often" ;)

I find DCS size to be fine on a 84+/SE calc, because you got at least 480 KB, but in your case you don't even have that much memory on yours, so when you develop in Axe that doesn't leave you much room for other apps. X.x (especially that you got so many projects and games)
