For pedagogical reasons, I would like to build one environment to display something like the screen of one Texas Instruments calculator.

What I'm looking for is a way to produce, via pdflatex, one pixelated font on Windows, Linux and also Mac OS.

Is it possible?

Well, as xelatex/lualatex with fontspec allow you to use TrueType fonts, you need only find a suitable font, I guess. – Torbjørn T. Dec 8 '11 at 9:47
The problem is that I can't use for the moment... – projetmbc Dec 8 '11 at 9:52
If you have some free time, you can make one yourself (since such font does not contain too much characters, and their shapes are "easy", this is probably less work than it might seem, and probably some fun, too ;) ) and draw it in tikz. In such a case, pdf(la)tex is enough. That said, a ready-made font is probably a better idea anyway. – mbork Dec 8 '11 at 10:02
If you're bound to using e.g., pdflatex, you should specify that in your question. – Torbjørn T. Dec 8 '11 at 10:03
I did a general tidy-edit on your post, but I also removed the dollar symbol in the interests of keeping this platform agnostic. – qubyte Dec 8 '11 at 10:08

I am absolutely no expert on this, but couldn't you use this howto on using ttf fonts in pdftex, and this pixelated font to achieve your goal?

Update: There is even a site over at Ti which gives you the fonts for the keys of all the Ti calculators, if you need to explain in the text which keys are to be pressed.

Thanks for the links. – projetmbc Dec 8 '11 at 10:49
This has all the ingredients of a good solution, but as it stands it's more of a comment. You should complete it... – qubyte Dec 8 '11 at 10:49
There's also a pixelated font that includes the math characters that would be needed: tibasicdev.wikidot.com/83lgfont – Jake Dec 8 '11 at 10:50
@Arne : the problem is that I would like to find an easy way to do that so as to share my environment with other users... – projetmbc Dec 8 '11 at 13:14
@projetmbc Package up the LaTeX file and the font in a compressed (zip, tar.gz, 7z, tar.bz) archive and send that out? – Canageek Dec 8 '11 at 15:20
