can't come up with a definition either. Maybe anything smaller than the smallest
mainframe and bigger than the biggest PC?
People who know about this stuff just
"know".
Agreed.
I recall there was a semi-serious list at some point (possibly here,
maybe on a.f.c.):
If you can lose a screwdriver in it, it might be a micro.
If you can lose a voltmeter in it, it might be a mini.
If you can lose a 'scope on a cart in it, it might be a mainframe.
There was more to it. Fuzzy memory.
Back around 1980, the criteria DoD used:
under USD 100K - micro
under USD 1M - mini
over USD 1M - mainframe
this was based on purchase price, since many systems were leased.
Just about every industry had its own criteria - usually an arbitrary
definition by either the bean counters or <mis>management.
