[mod.computers.vax] SID

JEllsworth@HI-MULTICS.ARPA (09/02/86)

I've been informed that the low 16 bits from the SID are what should be
looked at when determining the "unique system ID"

The format is:

     0-15  unique sid
    16-22  CPU top rev level
    23     RIght or Left CPU
    24-31  CPU type


So it seems we have some code that is looking at more than the the
low-order bits....
