OK.
I can state for sure, categorically, absolutely, postively, certainly, without
question, leaving nothing whatsoever to chance, beyond the shadow of a doubt,
that the 21066 has a slow memory bus. After all, it is code named the LCA
(Low Cost Alpha).
(Though it runs Linux much faster than my dog. On the other hand, I can't
get it to beg, shake, roll over, or fetch sticks; I've only taught it to play
dead.)
Cheers,
Eric
