Subject: Re: 0.35 Micron Pentiums vs. others

This issue remains unresolved after a week.  I have learned only that
there is supposedly no fab in Malaysia and that 0.35 micron is being used
in several U.S. plants.  I would like further clarification on the
process being used in the Phillipines, Ireland and Israel.

I am surprised about the easy question that was not answered, concerning
the difference between gold and black top Pentiums.  Also, am I correct
in understanding that no one knows how to tell from looking where a given
Pentium was fabbed?  I find this unbelievable.

Please keep this thread going.
