So "physics" is perfomed 4 times before the screen is updated.
This also applies to computer programs. Thus, your argument is invalid :3

Not that it matters much, but since I took the time to make it I may as well post it here in case anybody wants it. Here's my attempt at perspective-correcting the image: (maybe useful for screen measurements)

Uhu, but the refresh rate is about 60-90Hz

Because I'm pessimistic and skeptical, I suspect it will have poor compatibility and be locked down. If it is based on a Z80 running software based on the TI-84+ OS, it will probably come with BOOT 1.04, which will feature 8192-bit encryption---not just signing---, and will take approximately half an hour to validate.

I'll try to determine the resolution using photoshop

A color screen on a Z80? Isn't the TI-84+ slow enough already?

Read the other posts. It's probably a nspire in disguise.

Uh, even if it is, then it would not be using a Z80, would it? Because the Z80 is like maxed out in the 84+

-- EDIT: Oh nvm, " if the z80 processor stayed the same" - didn't read the "if"

At the time of this writing, nobody has sufficient definite information about the calculator, I'm afraid...

An 83+ with higher resolution and non-shitty LCD would be awesome, much more exciting in my opinion than a hampered nSpire packaged as an 84+. I really doubt they'd take asm compatibility away from an 83+, i would totally get one if that's what it turns out to be!

I'm betting it just runs a similar OS to the 84+, and really has an ARM processor. I wouldn't call that 'hampered' though, in the same way I wouldn't call a desktop running CLI linux hampered. A smaller OS leads to faster math.

TI still has the option of upping to clock rate of the CPU to at least 20 MHz; supposedly, they experimented with clock speeds of up to 25 MHz on the TI-83+SE, which was, for the young folks, the beta version of the TI-84+/SE.

I also second the idea of it being based on the Nspire, with the OS user interface rewritten to look like the UI of the TI-83+ series so that it's more familiar to teachers, who are of course the people TI actually markets graphing calculators too.

And maybe they'll just decide to stick a second Z80 in there for graphical purposes.

20 mHz is deathly slow nowadays, though. It would be far easier for them to base it off of the nspire architecture, with a new OS.

On a side note, I hope it is based off the nspire, because that would mean it would be fairly easy to port the linux launcher to it!

Oh, and the fact that it's running a higher resolution, color screen means that it's almost definitely not running the old 84+ emulator. If it is, I will be.....displeased.
