Pixelated font as on Texas Instruments calculators

Question

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 08 '11 at 09:47
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 08 '11 at 10:02
If you're bound to using e.g., pdflatex, you should specify that in your question. — Torbjørn T., Dec 08 '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 08 '11 at 10:08
I wonder how much effort has been devoted in the past to achieve the opposite effect... :) — Federico Poloni, Dec 08 '11 at 13:06
You're right ! :-) But for pupils, this kind of back to the past feature is very efficient. — projetmbc, Dec 08 '11 at 13:13
There is this font from the Font Catalogue, but while it is available on CTAN, it isn't in either TeXlive or MikTeX. Perhaps not exactly what you're after though. — Torbjørn T., Dec 08 '11 at 13:26
Consider using a regular monospace font instead. Frame it, maybe use a slashed zero variant, and you get a realistic calculator screen effect. A pixel font will just make the reading harder and stress the reader's eyes. — Andrey Vihrov, Dec 08 '11 at 19:33

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.

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 08 '11 at 10:49

There's also a pixelated font that includes the math characters that would be needed: http://tibasicdev.wikidot.com/83lgfont – Jake Dec 08 '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 08 '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 08 '11 at 15:20
