I don't know much about Sequent architecture, but I am interested in their
parallel/MP capabilities.  I was hoping someone could answer some questions for
me.  ...
 1- What are the naming conventions of the machines, specifically what is the
  difference between 1S27, 1S81, 4S81 models.  Is there a way to distinguish
  between models with X cpu's vs. Y cpu's.
 2- Do CPU upgrades come in batches of 2 CPUs at a time (i.e. colocated on a 
  single board ?) ?
 3- Just how symetric is the OS... How much of it needs to be on only one
  processor at a time ? I belive that it would be impossible to control a system
  where all processors have concurrent access to critical low level tables with
  out some sort of latching (therefore serial processing).
 4- Any other configuration and performance observations would be appreciated.

Please e-mail your comments to keep the bandwidth down.
