Quicken 6.0 for DOS dropped in 1993 and was basically the go-to personal finance software before everyone was doing online banking. If you were managing a checkbook in the ‘90s, you probably used Quicken—or knew someone who did. It gave regular people the ability to track expenses, balance accounts, and run reports without needing a finance degree. It built on previous versions with tighter budgeting tools, better category tracking, and faster performance, all in that classic DOS interface with keyboard shortcuts for everything. This was the version that really locked Intuit in as the top dog in personal finance software before Windows took over the scene.
