I received various reeponses.  The simplest is to look at your
/var/adm/messages because this number is reported at boot time.  Another
suggested I open the computer and look at the boards, but I am certain I
do not know enough to make sense out of raw hardware.  Another suggested
looking at the source of 'top' to see what it is doing. 

My /var/adm/messages file reports 16MB, but top still reports something
quite different.  I have not bothered to do the latter suggestions.
