Hadn't heard of a Nat SemiCon CPU before. Sounds like it was a

Nope - a micro. See:

National also had a PACE (16 bit) and SC/MP (8-bit) micros. I used the PACE
for a few years in the mid-late '70s. I liked the instruction set but it was
a little on the slow side (16-bit data word with only an 8-bit ALU). It was a
takeoff of the DataGeneral, IIRC.
