I, perhaps, owe my career to DOS. As a kid, everyone relied on me to get their games, soundcard, and disk drives to work. Juggling IRQs HIMEM and CHKDSK. Soundblaster 16 forever!

It's surprise for me that there are still non-opensourced MS-DOS versions. Why keeping them closed? And I see no reason not to opensource early Windows versions (up to 2000).
