That's the RF that doesn't work at all, or gives just some wavey lines, something like that (it's been years). Presumably because it's PAL output was choking my NTSC television set.
I'd be interested in hearing more about this hack to set the machine to NTSC. Last time I looked into it AFAIR it was some horribly complicated thing that involved soldering some pins, wires, etc., on the motherboard. Aagh why Commodore why couldn't you just put a jumper setting?? ;-)
Also can you give me more info on this "Pal on ntsc should always give a blackn white picture as should ntsc on pal," - is that just the way it is, or is there some logic in the video system behind it? Are you saying that if I had a genuine NTSC A1200 MB I'd get a color composite out on my NTSC video hardware?
Thank you very much.
