Don't know about that. But I do know that Ken Olsen was involved in magnetic logic -- it's his thesis subject -- which is at the basis of core rope ROM memory design. There's a reference to his work in one of the 1960s era papers about core rope memory. (It names "Olsen" without first name but I assume there weren't two Olsens at that lab doing that work.)
