[...] but you needed to know 6809 or 68000 assembly to
create anything
new for the OS itself,
Wasn't that the norm at the time, though? As I recall one of the
things that really set UNIX apart from other operating systems up
until about the early 1990s was precisely how machine-independent it
was by virtue of (with the exception of the early versions) having
been written in something other than assembler.
