 When ""Polarstar"" systems and a new naming convention were introduced, the VAX 8800 was renamed to VAX 8820N to distinguish it from the VAX 8820 ""Polarstar"".After the name adjustments and upgrading to full SMP capability, the former VAX 8700 and VAX 8800 models became VAX 88x0 machines, where "x" represented the number of CPUs, i.e.VAX 8810, 8820, 8830 and 8840.
