Am I the only one who thinks phrases like "that one typewriter font you get with Windows" are too vague to be much good? This may sound like a stupid question, but you know people exist that can't call Courier by name... or did I mean Courier New? Imagine talking about SCI font resources. You'd think "0.fon" is always the thick one, but it's not; Conquests of the Longbow, Quest for Glory 1 VGA, and Space Quest 4 have a thin squarish font, Police Quest 3 has the smaller common font (usually 3 or 4) as its 0, and Space Quest 1 has a stylish thin serif. So you can't just refer to 0.fon and always be understood as meaning the thick one. (Did you know that the 0.fon in LSL3 is the same as always, but with an LSL3 logo added?)
But if you say "Times New Roman", you know the type.
I'd like to humbly suggest giving these various SCI fonts proper family names for discussion in the community. For example, the five most common fonts could be Sierra System, Serif, Sans, Small, and Debug. Fonts that appear mostly if not exclusively in Space Quest could be Wilco -- SQ4 60 and 61 could be Wilco Serif and Wilco Serif Outline.
Thus, most SCI games have Sierra System, but some replace it with Sierra Square, or even Sierra Small.
