If you go to
Space Quest.net , I believe you can download the movie from the SQ Collection where Barry T. Smith goes to Sierra and interviews people (very funny!). One of the people he interviews is (supposedly) one of the legal staff at Sierra, and she starts naming all the people/companys that have brought a lawsuit against them. When she comes to the Duracell/Energizer thing, she says "...Duracell, or was that Eveready?"
