C64 S-Vid AV cable works on Genesis!

Hey guys I made this cool discovery today. The S-Video/Mono AV cable from a C64 works on a Sega Genesis! The model 1 (larger) Genesis uses an 8-pin DIN just like the C64 but what are the chances that out of the 8-pins in there the 2 we need (composite video and mono audio) just so happen to be in the right spot? Well they are! Sort of, don't match the colors. My C64 has a yellow, red and white jack (yellow and red being S-Video split) and out of these the yellow = mono audio and the white = composite video. So its backwards on the TV but it works great!

I still think this is amazing. The Genesis uses 5 of the 8 pins. 3 for R, G, B, 1 for Composite and 1 for Mono audio (the original Model 1 Genesis doesn't output stereo audio out the back, only out the Headphone jack or SegaCD expansion port) but the fact the 2 of the 8 pins are where we need them is lucky!

So there you go, many of us have a C64 and many of us have a good old classic Model 1 Genesis and perhaps like me you had AV cables for it all along and never knew it!

My own old AV out cable (DIN5 though) will work with a MD1 same way, audio comes from where video is supposed to and video comes from where audio is supposed to. My cable has stereo support, and 2nd audio line will have only +5V in it (I think, don't remember anymore).

i knew it worked somewhat i have a plug that has 4 rcas comming out of it i guess the middle pin is ground and the others are the centers of the other rca jacks so it is kind of lucky or maybe it is just a form of standard on certain monitors

Turbo Duo/PC Engine and various midi DIN cables also work. Back when there was a shortage of quality Duo video cables I ordered a bunch of midi cables, cut off the unused cords and color labeled them with stickers. They actually produced a slightly clearer picture than the set of old Duo cables I had been using. :p

The Neo Geo din cable will work on the Genesis as well.

Right, I can use the same cable on my TI-99, Atari 8-bits, Genesis, SMS model 1, C64, Vic 20, and C128.

The sound for the computers doesn't match the Genesis, though, it's another video output. 800XL pinout.

Is there any way to and would it actually work to take the two S-video components out on the C64 cable and wire them into a proper S-video cable end to get S-video directly out of the Gen I?

Its an S-Video cable for the C64. The C64 puts out the Chroma/Lumen over two separate RCA leads. The Genesis doesn't output S-Video at all. This is useful to me personally as I didn't have a Genesis AV cable to begin with so I was happily surprised to find the extra C64 cables I had lying around worked! No this doesn't gain you S-Video or anything over the stock Genesis AV cable but it was free for me and beats using RF!

I don't have the hardware to test it, but can the Gen be hooked to an RGB monitor, sonce the pins are there??

MN12BIRD, it sure does beat RF. Now, how to make it output VGA...
