I bought a camera from helmetcam.com for $250 (includes camera lens, battery, mic and recharger) and have mounted the camera on my helmet, my front fender and my rear fender. Images are awesome! It mounts using heavy duty velcro which has been tested to 200mph (so they say). I've tested it to 150mph with no problems. It is a worthwhile investment in fun.
I am guessing your Super8 doesn't have a USB port on it. You need to go to Radio Shack and buy an analog(RCA) to digital cord. Depending on what type of set up you have on your computer will determine what is on the opposite end of the cable. You can get one with RCA-USB or if you have a video card with external RCA plugs, you can just run RCA-RCA.
