What a waste of processors!  If you are looking for a 4 MIP unix
machine you should consider the ELXSI machine.  It starts out in a 
ONE processor config that runs 4 MIP and progress to a 10 CPU machine
that runs at 40 MIPS!  (yes, a 100% gain for each proccessor).  The
one cpu machine is upgradable a cpu at a time through 10.  As far as
pricing goes, I can't recall details.  

By the way, this machine runs a System V port.


* I have no link to ELXSI, except as an interested bystander....

	There are several reason why I would chose a multiprocessor machine
(such as the Sequent Balance 8000 or the Flex/32).  The first and most important
to me is reliability.  A multiprocessor machine such as the Balance 8000 is 
redundant.  That translates to a greater uptime factor.  Second it encourages
parallel processing in the design phase of a project.  I mean, you can't use
the old  'there's only on processor arguement'.

Now for why I responded.  For most timesharing/development activities a multi-
processor system is better that a uniproccessor system.  This becomes more
apparent when you have a large (what ever that means) number of users doing
different things.  In a non master/slave system, processors will handle
jobs simultaneously rather than serially.

Second, the Elxsi 6400, while being a dream machine for me, is ECL (emitter-
coupler logic) based machine.  That means high power consumption and (in my
experience) higher rate of failure than TTL (transistor-transistor logic)
based machines. I speak from a positions of a person who did (last year) a
evaluation of machines to challenge our Vax 11/780s at a previous job.

Note an important difference between these two machines:  the Sequent
machine exists and has been delivered to customers.  The Encore box, last
I heard, was still vaporware.

Any users on the net actually using the Sequent box?  If so I would
greatly appreciate hearing your views and opinions on this machine,
by mail please. I'll summarise if I get more than 2 responses.
