Co., Everett, WA Lines: 18 I had occaision to open my c64 up at one time and pry up the metal cover over the video circuitry. It turns out that this cover serves not only as a shield for EMI but also as a heat sink for the VIC II (video controller). There is a dab of heat sink compound on the VIC that makes thermal contact with the metal shield. My c64 had only a tiny dab of heat sink compound. Since I feared it would not make contact when I closed the case, I got a tube of the stuff and put a generous dollop on the top of the chip. The result was that my c64 has noticably sharper video now, presumably due to the fact that my video controller is running cooler. Now, I can't recommend you dissassemble your computer just for fun, but if you are having trouble with ugly video you might try this. -- Kurt Guntheroth John Fluke Mfg.
