[COFF] Terminology query - 'system process'?

[steve jenkin]

Noel,

Adding a little to your observation on how fast CMOS microprocessors took over.

Wasn’t just DEC and IBM who were in financial trouble in 1992:
 - the whole US minicomputer industry had been hit.

DEC did well to just survive, albeit only for another 5 years before merging with HP.
