Paul,

  There are a number of reasons. Lower speed support chips is one. But, just
as real is power and heat for the 21064. I think in the DEC 3000 Model 500 it
is running @23-25W of power. Which requires quite a bit of cooling. That is a
bit of a hurdle in compact desktop boxes (one which most vendors are having to
think about now...). 

  Cost is another factor. By using slower speed chips in entry level products
we can offer products at lower costs.

I hope that helps.

				Thanx,
				  AJ
