I'm working on a circuit that can demodulate the NTSC output of an Apple //c to a YUV component signal. This is the basic concept of the circuit working, which currently only decodes the red difference signal, which is why the colour is lacking. I have run out of resistors needed to wire up the blue difference signal. I'm using MC1496 mod/demodulators.
I'm in a PAL region (Australia) and have a PAL //c without the composite module. This circuit should work unmodified with NTSC machines too.
More coming.
