Michael Dell: Yeah. I wanted to see how it works, so I took it apart.  A good thing about the early personal computers is that they had completely kind of standardized chips, and so you could literally get a book about each chip and read what each pin did, and how signals were processed through the chip.  You could design your own circuits and you could modify them, and you could literally see exactly how the thing was working.  That was sort of the classroom for me. That was where I learned the basics of how these things worked.  Then I kind of became fascinated with, “Well, how could you improve it?” How could you make it do more things? How could you expand it? How could you make it go faster? How could you hook it up to other computers and let your imagination run wild?
