Fortunately, one of my C64's is in fact a doorstop, so I have no qualms about salvaging it. If we were talking about, say, my working ColecoVision, heads would roll before I'd take it apart...
I love my ColecoVision too. My friends and I wasted hours with Donkey Kong and Buck Rodgers on it last spring. Greatest system ever. I just need to find more games for it now.
Although I'm anxiously awaiting the arrival of my atari 2600 that I just ordered.
