This font is derived from the x3270 font, which, in turn, was translated from the one in Georgia Tech's 3270tool, which was itself hand-copied from a 3270 terminal. I built it because I felt terminals deserve to be pretty. The .sfd font file contains a x3270 bitmap font that was used for guidance.

The format

This font was built with FontForge. You'll need it if you want to generate fonts for your platform. On most civilized operating systems, you can simply apt-get install fontforge, yum install fontforge or even port install fontforge. On others, you may need to grab your copy from http://fontforge.org/. I encourage you to drop by and read the tutorials.

Adobe Type 1, TTF, OTF and WOFF versions are available for download on http://s3.amazonaws.com/rbanffy/3270_fonts_1aeb375.zip for those who would just like to use them.

If you are running Windows, you'll probably need something like Cygwin, but, in the end, the font works correctly (with some very minor hinting issues).

Generating derived files

The script generate_derived.pe calls FontForge and generates PostScript, OTF, TTF and WOFF versions of the base font, as well as a slightly more condensed .sfd file with the base font narrowed to 488 units, with no glyph rescaling and its corresponding PostScript, TTF, OTF and WOFF versions.

Contributing

I don't think GitHub's pull-request mechanism is FontForge-friendly. If you want to contribute (there are a lot of missing glyphs, such as the APL set and most non-latin alphabets which most likely were never built into 3270 terminals), get in touch and we will figure out how to do it right.

Preserving history

I regard the history of electronic computing a very important part of our civilization's history. Consider donating to entities that help preserve it, such as the Computer History Museum (http://www.computerhistory.org/), the IT History Society (http://ithistory.org/) and many others around the world. If you have a historically significant piece of technology in your closet or garage, consider contacting a local technology or industrial-design-oriented museum for advice.

Known problems

Not all symbols in the 3270 charset have Unicode counterparts. When possible, they are duplicated in the Unicode space. The 3270-only symbols are at the end of the font.
