OK, so ignition systems with ballast--either external resistor or
internal to coil--use points/condensers than can't handle 12V+
continuously (makes sense--the bean counters can save a few
shillings)? Don't Healey points switch 12V+ continuously?
My main point was that Healeys don't use any ballast--so that's
correct?

If you use a coil that requires an external ballast resistor on a
car with no external ballast resistor I can assure you that the
distributor will in fact care. A lot. The points are not designed
to switch full system voltage, and if there is not ballast resistor
in the system (external or internal) the excess voltage will lead
to excess arcing of the points and them burning out very quickly.
In the case of an electronic system will this cause issues? I
don't know as I am unfamiliar with the particular system being
discussed. On some electronic systems, you might pop a power
transistor.

Don't ballasted systems require two primary circuits; i.e. one for
starting (non-ballasted) and one for running (ballasted)? The
distributor won't care, as it switches the primary circuit--12V or
otherwise--to ground.
