I believe my answer was correct with respect to programs labelled "SPICE".
You were correct that the research work was at "one of the California
universities" (U. Cal. Berkeley), and it's true that a Ph.D. thesis was
involved. The PhD thesis was not the grandfather of SPICE; rather, it was
a summary report about the development of SPICE. The thesis is dated 1973,
the same year SPICE1 was released to the public.
Your timeframe is off. Early 1970s, not mid to late 60s. CANCER, SPICE's
ancestor, was very late 60s to early 70s.
In that time, and especially in the 60s, MOS was an uncommon technology.
Far more electronic circuits used BJT transistors than MOS. The benchmark
circuits that were developed with SPICE (included in Dr. Nagel's thesis)
were quite BJT-centric. Back then MOSFETs may have had more analog
applications, than digital.
