       <Steve>	Is too.  Tell me something a 64-bit processor will do
       <Steve>  more slowly than a 32 bit processor.  (I can think of

                NOPE. I didnn't ask this question. What I asked about
                was if the Red Hat LInux for Sun's Sparc would also
                be a 64-bit OS - which Jim T. kindly answered that it
                was just 32-bit.

     Yep. I'm not running any native *64-bit* application, Ted. How
did you guess that?  :-)

     I read once in a magazine that 64-bit OS will be a boon to IC
design engineers in their circuit simulations. I think it has some-
thing to do with addressing "memory space" ( not sure about this 
term ). With 32-bt OS, they have to logically divide the circuit and
do the simulations on a number of separate machines. Now, with 64-bit
OS, they can do it on just a SINGLE machine. Armed with a VERY cheap
64-bit Linux and one of the ALPHAs or SPARCs, don't you think that 
someday, IC design engineers TOO will telecommute, just like software
programmers, doing their simulations at home?  :-)
