Also, the sentence starting "The VAX instruction
set well revered would later on influence" needs restructured. The paragraph after
the bullet points has more of the same error.
You could say that the designers of the 68000 were influenced by the
PDP-11, but I do not think you could say the same thing about the VAX.
When the 68000 design was started, the VAX was still well under wraps.
I can see no reason why DEC would have let the Motorola guys see the
developing architecture.
Anyway, in the mid/late 1970s, heavily microcoded very CISCy
architectures were pretty much the design route of choice. It was
everywhere. It is very difficult to pin down influences.
