I fixed up a Nintendo 64 this past weekend. People of a certain age affectionately refer to it just as “the 64,” though to me, “the 64” refers to a computer with 64K of memory introduced in 1982. I have an inherent bias against almost anything that reminds me of 1997, but in spite of my biases, I found a number of things to like about the system after spending a few hours with it.
Commodore and Atari used an early implementation of s-video on their home computers in order to show off their computers’ advanced-for-their-time graphics. Many monitors sold for those computers featured compatibility with this feature, which was called “separated” or “y/c” composite or at the time. JVC called the feature “s-video” when they started using it on their SVHS camcorders starting in 1987, and JVC’s name stuck. Other companies followed suit, and s-video and the mini DIN plug became an industry standard.
Commodore and Atari used a different connector than JVC did, but all it takes to use s-video gear with those old monitors is a cable, which you can make with about $10 worth of parts from Radio Shack. Read more
It is less than obvious how to connect a Commodore 64 to a television, especially a modern television, and it’s even more difficult if your C-64 didn’t come with the cables or the manual.
There are, as it turns out, several ways to do it. The C-64 and 128 have an RCA jack on the back that matches the RCA jacks on most televisions, whether LCD or CRT. Confusingly, this isn’t the key. If you just plug a cable from the RCA jack into the RCA input on a TV, you won’t get a display.
