My real answer is none of the above. I would like to see:
1 - A calculator with all functions and features of all calculators and some extra ones to compete with of brands/calculators.
2 - A excellent OS. Small, Efficient, Yet pretty, and functional.
3 - Good Software for both the calculator and computer. Again small, fast, and advanced. Assembly and BASIC debugger, emulator, a good IDE and fast, convenient linking software.
4 - Faster processor and more memory, not to the point of absurdity though.

More memory or an expansion slot might be nice. A color screen would only be good for graphing or the OS. A color or touch screen would be incredibly horrible idea. Think of the cost and innefectiveness of it. 1000 tic-tac-toe games for the 83 Plus... NOW IN COLOR! Or maybe you can not see the graph screen because your fingers are all over it or the resolution is horrible. Think of how hard it would be to program for any of those in any language. What would you take pictures of and for in a black-white/small bit gray scale/16 or less colors? A phone? Come now? Who would provide service, think of the size, the battery comsumption, the price? For any of these features!

I apologize for this poorly written comment, but hopefully I get something across. I can be more specific perhaps later?

I agree with your first four points.

There already is a *limited* assembly debugger for the TI-83+ called CHASM. It's a FlashApp, and it's pretty neat (except that you can only use HEX numbers and some larger addressing doesn't work).

Yeah, I've tried it but I don't like it.

It's not a debugger. Just an assembler.

Sorry. Pardon my confusion with this jargon.

Yeah... Like DEBUG.EXE is an assembler too... (Albeit crappy.)

Didn't some guy make a Pong game for the 83+ that had yellow and blue color on it???? it may have been a while ago, and i put it on my calc but it didn't do anything.

Rumor has it that you can overload the LCD driver or use interrupts and create at least blue pixels to my knowledge. I have not heard of yellow, or any way to "control" it in any shape or form.

i had that game once. it was kind of blue, more like the contrast was so high it appeared blue. and the paddle and ball could be called yellow if you wish. it was weird looking and i don't like pong anyways.

Yes, our esteemed news editor made that game that doesn't really deserve a featured program award.

yes, i made a Program called BlueLCD that changes the entire screen blue and after a while, looks like it's eating away the LCD. It's different from color pong, which does something like turning up the contrast. You can download BlueLCD from the link.

Not to be rude or anything, but I really do not feel like downloading it to check if you have the source, muchless run the program, but if you would not mind, would you divulge how you accomplished such?

END TRANSMISSION

Probably by screwing around with the calculator until he got something cool, and kept it. On my TI-82, I made the coolest program ever. Wanna see the ASM code?

#INCLUDE "CRASH82.INC"
.DB "Die",0

That's it... no return statement. It's actually very cool (if run on an emptied calculator, just with the shell) I guess it would differ from the other programs that you had on your calc.

Heh, interesting program indeed. If you have MirageOS on your 83 Plus, you can run 82 programs. A lot of people do not seem to know that. Anyhoo!

What's it do? Does whatever it does work in VTI?

I wouldn't run it too much. I ran it for 5 minutes on an 83+ once which was half broken. Now, the LCD driver is compleatly broken because of the Blue thing.

Yeah, when I had it on mine, I only ran it for about 20 seconds to show it to people...

Also, when you quit, you can see that the bottom of the screen slowly-ish changes back to normal, and if you then crank the contrast, that is is lighter than the top (which wasn't blue).

it doesn't break the LCD driver, because Swtaars left it runnning on a calc for 6 hours and he said it still worked fine afterwords.

<nonjerk-comment>Heh, you can not really break a driver. You might be able to corrupt it with a magnet or something lol. Stupid technicality. Ignore me. I am not trying to be a jerk or anything. I was just bored and found it funny.</nonjerk-comment>

It's impossible to break the DRIVER, unless you screw up the EEPROM :p

Now, you CAN screw up the actual LCD panel...

Yes, it's pong1, which was written by mv.

It doesn't work on my friend's TI-83+SE. When I installed it, it did funky things, and then kind of messed up.

*makes mental note to never install it on his TI-83+ SE*

What did it do to it?
