Memories of seeing my Dad’s boxed copy of “Doctor DOS” sitting on the bookshelf next to his 286 PC are forever burned into my brain. Using DR DOS and XTree on that computer was my first taste of PC usage. Prior to that I’d only been allowed to use the family Atari 800. Years later, when Wolf3D hit the scene, I finally managed to convince him to let me upgrade it to MS-DOS 6, install a VGA card, and upgrade to 4MB of RAM.
