The traditional nomenclature is that you have one CPU (that's the one with
the keypad) and two expansion chassis.

Sometimes systems came with the diagnostics on paper tape (DEC paper tapes
are all marked on the leader with their function, if they start with the
letters XX then they are diagnostics so save them!)

So it seems there was some S100 stuff there too.

It is ok to store them in an unheated garage but it is not recommended that
you operate them over wide ranges of temperatures. Moving them to the
basement would be a Good Thing however and preserve your investment in time
and effort.
