Question ELECTRICS - what happened?

Driving along, Porsche 930 with twin plug MSD ignition .... and sputter, miss....voltmeter reads under 8 volts.

Gets worse, more missing as if spark occurs only every 3 or so firing chances.
New battery added today and fires and runs - (former battery was 6 yrs old anyway so got a new Odyssey as a matter of course)

Alternator 100%? Was the battery providing all the energy and the alternator doing zip?

Not certain, haven't had an alternator go out on a car in years!
