Yes, the PDP-11 instruction set is very nicely orthogonal.  However,
that does *not* mean that making the 68k instruction set a superset
of it made it just as (or even more) orthogonal.  In fact, the 68k
instruction set has many non-orthogonal "extensions" which make it,
to my mind, less orthogonal than the PDP-11, and certainly not the
32-bit-PDP-11-extension I was expecting from all the advance hype.
I was happy to stick with my MACRO-11.
