MonospaceTypewriterDZ is Manfred Klein's fantastic MonospaceTypewriter font modified for programming usage. The original font does not distinguish betweeen 0 and O, so a dot has been added to 0, hence the name DZ(Dotted Zero)
MonospaceTypewriter provides good readability while being a rather slender typeface. It has a “retro” personality but not too much to be a distraction.
