I believe you're thinking of the term 'microcomputer', which describes a computer the size of what we would now call a PC and is no longer in common use. I was unable to find the word 'microsystem' in any dictionary; if it was in common use as recently as 30 years ago, it seems unlikely that I would not be able to find any trace of it today. Therefore, I reiterate my assertion that 'microsystem' is a silly word that the people at Sun made up for their company name, until proven otherwise :) Wikipedia does have an entry for 'microsystem'[1], but it says the term is not generally used in the United States and does not seem to have anything to do with what we're talking about (much more recent category of technology than existed at the time that Sun was founded).
