The 1801 dual-chip was basically the "development version" of the 1802, and afaik was NEVER made as SOS. Afaik, NO ONE used it commercially. It's NOT speculative that 4000 CMOS were used in the Voyagers. It is in the design specs and documentation, which were worked on "WAY before" the 1802 was commercially available, especially when using it would have been "bleeding edge" development, which is NOT what NASA et al. did. "SOS technology was being developed at that time to be used for the military and space applications in some kind of secrecy, way before it was commercially available to the general public." is EXTREMELY speculative and most probably untrue.
