Know It? DOS 5.0 Volume 1

Know It? DOS 5.0 Volume 1 is, as you might expect, a quiz game on the MS-DOS operating system, specifically version 5.0, although I suspect most of the questions would still apply to later versions. The quiz game is presented in text mode, and just asks you multiple choice questions, one after another, playing a little PC speaker ditty after you answer, until you eventually call it quits. It's interesting that the game concentrates so much on MS-DOS 5.0, since only a few months after this game's release 6.0 was released, which would quickly eclipse the older version.
