The word "single" in this case means "one" or "only". It is necessary here because is it used to emphasize that that one course alone helped to create multiple typefaces and proportionally spaced fonts on the Mac and other computers. You could drop the word "single" here, but it would take away the emphasis of that course being the one course that led to Steve Jobs' invention of this. Here's a few examples of "single" in similar contexts: Ex: She is the single most important person in my life. Ex: The good weather is the single reason I'm living here.
