One of my family friends is a programmer, so when I got into filk, I started collecting computer related songs to share with her. Do-It-Yourself, also known as Mainframe, is a catchy little song about building your own computer from the things you find at home. You can tell Bill Sutton had fun with this song. The snark about the computer companies that were around at the time is smirk-tastic. Especially the cracks on IBM. This came from his tape: Past Due. It's an old song, and I only know about half of the references in the chorus, but it's entertaining anyway.
