Yes, starting from OS 5.1.5, you can now connect and use a standard USB keyboard.  ;D

You need a male mini-USB type A to female USB type A adaptor.

At last ! we had to wait for 12 long years since the TI-84 Plus release in 2004... :P

Critor will probably explain it here better/in more details soon, but in the meantime, here are a few words about something cool :)

It turns out a TI-Planet member saw that a few days ago "randomly" : for some reason Get() and Send() appear at the top of the 83PCE catalog. Those were not present in previous versions :)
Anyway, the CE online help mentioned this :P I asked the eGuide team about it a while ago but they didn't reply... No need anymore I guess.

And on a [probably very] related note, critor got a standard USB keyboard working with the CE:

I think @CVSoft will be happy about this :P

Also nice Critor :)


I'm now finished documenting the USB Qwerty keyboard, as seen by the TI-84 Plus CE :

The yellow keys are the ones whose main behaviours (main function or function accessible via the Shift key) really differ from what's written on them.
There are only 8 of them. :)

The functions accessible via the Alt or Ctrl keys aren't hard to memorize at all, as they are just the two remaining functions associated with the matching key on the TI-84 Plus CE keypad. :)

Have fun ! ;)

Azerty and TI-83 Premium CE versions are available too.

If you need to fix some things, or to adapt for other keyboard layouts like the german Qwertz, get the source document :

Thanks critor for this pic. By different behavior do you mean for exanple that Shift will not do the same thing as on the calc keypad, or just that the names are different?


For example, the 'num lock' key behaviour has nothing to do with its description, triggering the 'clear' key from the calculator keypad.

Shift doesn't trigger any key on the calculator. It's a silent key modifier.
What it does is specified in orange on each key.

Maybe they use macs. On apple keyboards, there is a delete key instead of numlock.


Quick question: What does the second cable the TI 84+ CE comes with do?
Does this qualify as a signature? 
The answer is "Sure."

DJ Omnimaga

If you mean the small cable, then it's to link two calculators together.


Does this qualify as a signature? 
The answer is "Sure."
