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 series 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. If you are running Debian or Ubuntu and you don't want to mess with building your font files, you can simply apt-get install fonts-3270 (It's available from the Debian (https://packages.debian.org/sid/fonts/fonts-3270) and Ubuntu (http://packages.ubuntu.com/zesty/fonts-3270) package repos at https://packages.debian.org/sid/fonts/fonts-3270 and http://packages.ubuntu.com/xenial/fonts/fonts-3270, although the packaged version may not be the latest version, but it's good enough for most purposes. For those who don't have the luxury of a proper system-managed package, Adobe Type 1, TTF, OTF and WOFF versions are available for download on http://s3.amazonaws.com/3270font/3270_fonts_b3b4b7d.zip (although this URL may not always reflect the latest version).
