This is why I collect, maintain and most importantly, make available at a whim many old consoles and computers. Anyone can experience the joy of instantly available basic, duck hunt, Mario paint and many other classic and historically significant games and programs more easily than even when I was a kid.
I use LG auto switchers to connect everything so anyone just has to turn on the equipment they want to use. On top of that I also have an av switch reversed so one can choose between the big screen or the crt.
