Oh man, QBasic was the first programming language I ever encountered and started playing around--what great times!

At the time (I was probably 11 or so) I knew that it was important to learn to write serious stuff, and knew that an operating system was probably "serious stuff," and so I thought it might be a good learning experiment to write an operating system in QBasic. Needless to say I was missing a few links in how "serious stuff" was written back then, but it sure was a fun intro!
