The first computer I purchased arrived at my home with two operating systems: DOS and Windows 3.1. Most full-fledged programs ran in DOS, including nearly every game in the early 1990s. Besides pool, the game I played most during my college years was called Links Golf which ran in DOS. Without Links I’m convinced my GPA would be at least a half grade higher. I offset my Links addiction by installing WordPerfect for DOS which allowed me to write reports from home instead of the school’s computer lab
