this joystick to usb connection maker guide?

i have an ancient Saitek megagrip VIII joystick and it has one of those 15 pin connectors. my problem is... either i kick the port out of the front of my old computer and try and fit it into my new computer or i build a connector (buying a new joystick is out of the question because im cheap like that)
so, are there any guides on making an adapter like thing that will change the 15 pin (DSUB i think it is) joystick output into a USB connector
i have the USB as i have an old data cable for my mobile phone, and the rest is in the joystick
cheers
