The circuit would be quite different, since there was no PAL version
of the MC1372 afaik.  On the other hand, I think Simon indicated
that his CoCo2 had composite video at the input to his modulator.
If that is true across the various models, then something like what
is done for the CoCo1 (i.e. no circuit or just an amplifier) should
work for them as well...?
