	"I feel the 88k has a slight edge by not having the internals
	of the pipeline visible to the compiler."

A decent 88k compiler will still keep its eye on pipeline internals or
the performance of its generated code will be poor.  The obvious
example is a load;store with no intervening instructions, which wastes
at best two cycles and at worst a dozen or more.

The 88k scoreboard hold system just allowed 88k developers to get
started with stupid compilers while awaiting good compilers.  And boy,
have I seen some stupid compilers ...
