Re: Debian on Sparc
Ok my first statement was based on the present netra line and not the original models. My
exposure to sun did not come about until 4 years ago, so the hypersparc, microsparc sparcI
based systems are fairly new/old to me. The netra line from Sun now only uses the SME
Ultra Sparc II and not the ross/fijitsu clones. The older systems from what I gather are
not NEBS certified so the use of a clone CPU is allowed. I guess I am more interested
in the newer horsepower with dual/quad ultra sparcII's/III's, not saying that there is
anything wrong with the older models in question. My bad for the lack of clarification in
my initial statement.
Regards,
Mike
