AV output! I'm not 100% sure I have a spare SC-3000 AV cable I want to spare, thought. You can butcher a SMS one probably. Cassette requires a jack-to-jack leads. Any cassette drive with audio I/O would work.
I was just wondering, I have come across an SC-3000 and I am considering buying it, but according to the owner the TV/Game switch is broken. How would one go about fixing that, I assume it's not the same set up as the SMS? I need to learn more about this sort of thing, pardon my ignorance I am also sorry if I shouldn't post here, I didn't want to start a new thread for something so trivial , so sorry for the OT.
